Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	1 . Summary of Significant Accounting Policies Description of Business Landauer, Inc., together with the subsidiaries through which businesses are conducted (the “Company”), is a leading global provider of technical and analytical services to determine occupational and environmental radiation exposure, the leading domestic provider of outsourced medical physics services, and a provider of radiology related medical products. The Company operates in three primary business segments: Radiation Measurement; Medical Physics; and Medical Products. Additional information regarding the Company’s segments is contained in Note 1 6 . Basis of Presentation and Consolidation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of the Company, its subsidiaries and variable interest entities in which the Company has a controlling financial interest. All intercompany balances and transactions have been eliminated in consolidation. Entities in which the Company does not have a controlling financial interest, but is considered to have significant influence, are accounted for on the equity method. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents include all unrestricted cash and highly liquid investments with an original maturity of three months or less, primarily short-term money market instruments. Restricted Cash Restricted cash represents funds that are restricted to satisfy designated current liabilities. As of September 30, 2014, the Company’s restricted cash represented deposits from an international customer that were held from the Company subject to the achievement of specified conditions. This balance was included in “Other current assets.” The Company successfully fulfilled the conditions in October 2014 and the funds were released and no longer restricted. Receivables, Net of Allowances Receivables, principally trade accounts receivable, are generally due within 30 to 90 days and are stated at amounts due from customers, net of an allowance for sales returns and doubtful accounts. The Company performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness, as determined by a review of their current credit information. We continuously monitor aging reports, collections and payments from customers, and a provision for estimated credit losses is maintained based upon the Company’s historical experience and any specific customer collection issues that have been identified. While such credit losses have historically been within our expectations and the provisions established, we cannot guarantee that the same credit loss rates will be experienced in the future. The Company writes off accounts receivable when they are determined to be uncollectible. Inventories Inventories primarily include the components associated with dosimetry devices, which are stated at lower of cost or market utilizing a first-in, first-out method. Long-lived Assets Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Plant, equipment and internal use software are depreciated on a straight-line basis over their respective estimated useful lives. Dosimetry devices, principally badges, and the accompanying software are amortized on a straight-line basis over their estimated useful lives. Expenditures for maintenance and repairs are charged to expense as incurred, and renewals and betterments are capitalized. The following table provides a summary of estimated useful lives by asset category: Estimated Useful Lives Buildings and improvements 30 years Internal software 5 - 10 years Equipment 3 - 8 years Dosimetry devices 30 months - 8 years Long-lived assets, including definite-lived intangible assets, are reviewed for impairment whenever events or changes in business circumstances indicate that the carrying value of the assets may not be fully recoverable. The Company performs undiscounted operating cash flow analyses to determine if an impairment exists. For purposes of recognition and measurement of an impairment for assets held for use, the Company groups assets and liabilities at the lowest level for which cash flows are separately identifiable. If an impairment is determined to exist, any related impairment loss is calculated based on fair value. Impairment losses on assets to be disposed of, if any, are based on the estimated proceeds to be received, less costs of disposal. The Company also reviews the estimated remaining useful lives of long-lived assets whenever events or changes in business circumstances indicate the lives may have changed. Equity in Joint Ventures Entities in which the Company does not have a controlling financial interest but is considered to have significant influence are accounted for on the equity method. Under the equity method, a company records its share of net income or loss of an investment based on its percentage ownership. Additional information regarding the Company’s equity in joint ventures is contained in Note 6 . Goodwill and Other Intangible Assets Goodwill and other indefinite-lived intangible assets must be assessed for impairment annually or more frequently if events or changes in circumstances indicate that such assets might be impaired. Triggering events include, but are not limited to a current period operating or cash flow loss; a product, technology or service introduced by a competitor; or a loss of key personnel. Goodwill impairment testing first requires a comparison between the carrying value and fair value of a reporting unit with associated goodwill. Carrying value is based on the assets and liabilities associated with the operations of that reporting unit. The Company estimates the fair value of the reporting units using the income approach and the market approach. If the Company believes that the fair value of a reporting unit exceeds its carrying value by a substantial margin, the Company may perform a qualitative analysis instead. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not to be impaired and the second step of the impairment test is unnecessary. If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination, and the fair value of the reporting unit was the purchase price paid to acquire the segment. The impairment test for an indefinite-lived intangible asset other than goodwill consist s of first assessing qualitative factors, such as company, industry and economic trends. If determined to be necessary, the next step compares the fair value of the intangible asset to its carrying amount. If the carrying amount exceeds the fair value, an impairment loss is recognized for the difference. Additional information regarding the Company’s goodwill and other intangible assets is contained in Note 7 . Long-term Investments The Company had long-term investments of $3,509 and $3,734 at September 30, 2015 and 2014, respectively that are held in a Rabbi trust for benefits under the Company’s deferred compensation plan. Under the plan, participants designate investment options to serve as the basis for measurement of the notional value of their accounts. The investments, classified as trading securities, include a money market fund and mutual funds that are publicly traded. Trading securities are carried at fair value with unrealized gains and losses included in earnings. The fair values of the shares or underlying securities of these funds are based on quoted market prices. The Company had long-term investments of $1,763 and $2,382 at September 30, 2015 and 2014, respectively, consisting of fixed income mutual funds classified as available-for-sale securities. Available-for-sale securities are carried at fair value with unrealized gains and losses, net of tax, reported in other comprehensive income. The cost of securities sold is based on the specific identification method. The investments are valued based on the net asset value of the underlying securities as provided by the investment account manager. The investments are not restricted or subject to a lockup and may be redeemed on demand. Notice within a certain period of time prior to redemption is not required. Long-term investments are included in other long-term assets. Revenue Recognition and Deferred Contract Revenue The majority of the Radiation Measurement revenues are realized from radiation measurement services and other services incidental to radiation dose measurement. The measuring and monitoring services provided by the Company to its customers are of a subscription nature and are continuous. The Company views its business in the Radiation Measurement segment as services provided to customers over a period of time and the wear period is the period over which those services are provided. Badge production, wearing of badges, badge analysis, and report preparation are integral to the benefit that the Company provides to its customers. These services are provided to customers on an agreed-upon recurring basis (monthly, bi-monthly, quarterly, semi-annually or annually) that the customer chooses for the wear period. Revenue is recognized on a straight-line basis, adjusted for changes in pricing and volume, over the wear period. Revenues are recognized over the periods in which the customers wear the badges irrespective of whether invoiced in advance or in arrears. Many customers pay for these services in advance. The amounts recorded as deferred contract revenue in the consolidated balance sheets represent customer deposits invoiced in advance during the preceding twelve months for services to be rendered over the succeeding twelve months, and are net of services rendered through the respective consolidated balance sheet date. Management believes that the amount of deferred contract revenue fairly represents the remaining business activity with customers invoiced in advance. Other services incidental to measuring and monitoring augment the basic radiation measurement services that the Company offers, providing administrative and informational tools to customers for the management of their radiation detection programs. Other service revenues are recognized upon delivery of the reports to customers or as other such services are provided. The Company sells radiation measurement products to its customers, principally InLight products, for their use in conducting radiation measurements or managing radiation detection programs. The Company recognizes Radiation Measurement segment product revenues upon shipment or delivery of goods when title and risk of loss pass to customers. The Company, through its Medical Physics segment, offers full scope medical physics services to hospitals and radiation therapy centers. Services offered include, but are not limited to, clinical physics support in radiation oncology, commissioning services, special projects support and imaging physics services. Delivery of the medical physics services can be of a contracted, recurring nature or as a discrete project with a defined service outcome. Recurring services often are provided on the customer’s premises by a full-time employee or fraction of a full-time employee. Revenue is recognized for recurring services on a straight-line basis over the life of the contract unless there is another discernable pattern as the services are rendered. Revenue is recognized for fee for service projects when the service is delivered. Contracted services are billed on an agreed-upon recurring basis, either in advance or arrears of the service being delivered. Customers may be billed monthly, quarterly, or at some other regular interval over the contracted period. The amounts recorded as deferred contract revenue represent amounts invoiced in advance of delivery of the service. Management believes that the amount of deferred contract revenue fairly represents remaining business activity with customers invoiced in advance. Fee for service revenue is typically associated with much shorter contract periods, or with discrete individual projects, and revenue is recognized upon completion of the project and customer acceptance thereof. Additional medical physics services under the full scope offering of the medical physics practice groups comprising the Medical Physics segment include radiation center design and consulting, accreditation work and quality assurance reviews. The Company, through its Medical Products segment, offers high quality medical consumable accessories used in radiology, radiation therapy, and image guided surgery procedures. The Medical Products segment recognizes revenues upon shipment or delivery of goods when title and risk of loss pass to customers. The amounts recorded as deferred contract revenue in the consolidated balance sheets represent invoiced amounts in advance of delivery of the service, and are net of services rendered through the respective consolidated balance sheet date. Deferred contract revenue was $13,904 and $14,750 , respectively, as of September 30, 2015 and 2014. Concentrations of credit risk with respect to accounts receivable are limited due to the high credit quality of the Company’s major customers, as well as the large number and geographic dispersion of smaller customers. The large diversified customer base results in no single customer representing greater than 5% of revenue. The Company routinely reviews outstanding customer balances and records allowances for bad debts as necessary. Research and Development The cost of research and development programs is charged to selling, general and administrative expense as incurred and amounted to $4,579 , $ 5,813 and $ 4 ,121 in fiscal 2015, 2014 and 2013, respectively. Research and development costs include salaries and allocated employee benefits, third-party research contracts and supplies. Advertising The Company expenses the costs of advertising as incurred. Advertising expense, primarily related to product shows and exhibits, amounted to $1,023 , $ 1,191 and $ 1,339 in fiscal 2015, 2014 and 2013, respectively . Income Taxes The Company files income tax returns in the jurisdictions in which it has sufficient presence. The Company estimates the income tax provision for income taxes that are currently payable, and records deferred income tax assets and liabilities for the temporary differences in tax consequences between the financial statements and tax returns. The Company records a valuation allowance in situations where the realization of deferred income tax assets is not more likely than not. The Company recognizes the financial statement effects of its tax positions in its current and deferred income tax assets and liabilities when it is more likely than not that the position will be sustained upon examination by a taxing authority. Additional information regarding the Company’s income taxes is contained in Note 9 . Stock-Based Compensation The Company measures and recognizes compensation cost at fair value for all share-based payments, including stock options. The Company has not granted stock options subsequent to fiscal 2005. Awards of stock options in prior fiscal years were granted with an exercise price equal to the market value of the stock on the date of grant. The fair value of stock options was estimated using the Black-Scholes option-pricing model. Expected volatility and the expected life of stock options were based on historical experience. The risk free interest rate was derived from the implied yield available on U.S. Treasury zero-coupon issues with a remaining term, as of the date of grant, equal to the expected term of the option. The dividend yield was based on annual dividends and the fair market value of the Company’s stock on the date of grant. Compensation expense was recognized ratably over the vesting period of the stock option. Subsequent to fiscal 2005, key employees and/or non-employee directors have been granted restricted share awards that consist of performance shares and time vested restricted stock. Performance shares represent a right to receive shares of common stock upon satisfaction of performance goals or other specified metrics. Restricted stock represents a right to receive shares of common stock upon the passage of a specified period of time. Upon the adoption of the Company’s Incentive Compensation Plan in February 2008, the fair value of performance shares and restricted stock granted under the new plan is based on the Company’s closing stock price on the date of grant. Compensation expense for performance shares is recorded ratably over the vesting period, assuming that achievement of performance goals is deemed probable. Compensation expense for restricted stock is cliff vested and recognized ratably over the vesting period. The Company also retains the discretion to make additional awards to executives at other times for recruiting or retention purposes. Stock-based compensation for these awards can be either cliff or graded vested depending on the agreement, and recognized ratably over the vesting period. Forfeitures of awards are estimated at the time of grant and stock-based compensation cost is recognized only for those awards expected to vest. The Company uses historical experience to estimate projected forfeitures. The Company recognizes the cumulative effect on current and prior periods of a change in the forfeiture rate, or actual forfeitures, as compensation cost or as a reduction of cost in the period of the revision. Foreign Currency Translation Financial statements of foreign subsidiaries are translated into U.S. dollars using period-end exchange rates for assets and liabilities and weighted-average exchange rates for revenues and expenses. Adjustments resulting from translating net assets are reported as a separate component of accumulated other comprehensive loss within common shareholders’ equity as currency translation adjustment. Recent Accounting Pronouncements Adoption of Accounting Standards Updates In April 2014, the Financial Accounting Standards Board (“FASB”) issued revised guidance to reduce the diversity in presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. This requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred income tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions listed in the guidance. This guidance was adopted by the Company in the first quarter of fiscal 2015. The adoption of this guidance did not have a material impact on the Company’s results of operations, financial position and liquidity. In November 2014, the FASB issued new guidance on accounting for pushdown accounting in the event of a business combination. This update provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. This guidance was adopted by the Company in the first quarter of fiscal 2015. The adoption of this guidance did not have a material impact on the Company’s results of operations, financial position and liquidity. In April 2014, the FASB issued new guidance related to the definition of a discontinued operation and requires new disclosure of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. This new guidance is effective for annual periods beginning on or after December 15, 2014 and interim periods within those years. The Company early adopted this guidance beginning in the fourth quarter of fiscal 2015. The adoption of this guidance did not have a material impact on the Company’s results of operations, financial position and liquidity. Accounting Standards Not Yet Adopted In May 2014, the FASB issued new guidance for recognizing revenue from contracts with customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In July 2015, the FASB deferred the effective date of the new revenue standard by one year. Public companies would now be required to adopt the new guidance for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The FASB decided to allow earlier adoption of the new revenue standard, but not earlier than the original effective date. This guidance is effective for the Company in the first quarter of fiscal 2019. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In June 2014, the FASB issued new guidance on accounting for share-based payments requiring a specific performance target to be achieved in order for employees to become eligible to vest in the awards when that performance target may be achieved after the requisite service period for the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period for which the requisite service has already been rendered. This guidance is effective for the Company in the first quarter of fiscal 2017. Early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In August 2014, the FASB issued new guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of doubt about the entity’s ability to continue as a going concern. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. This guidance will be effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity. In January 2015, the FASB issued new guidance on accounting for unusual and infrequently occurring items, which eliminates the concept of extraordinary items. An unusual and infrequently occurring item will no longer be classified as an extraordinary item and segregated from ordinary operations in the income statement, but will be shown as a component of income from continuing operations or separately disclosed in notes to the financial statements. This guidance is effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity. In February 2015, the FASB issued amended guidance on the model used to evaluate whether certain legal entities should be consolidated. This guidance is effective for the Company in the first quarter of fiscal 2017. Early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In April 2015, the FASB issued new guidance on the presentation of debt issuance costs. This update requires a company to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with the presentation of debt discounts. Currently, debt issuance costs are presented as a deferred asset. The recognition and measurement requirements will not change as a result of this guidance. The update requires retrospective application and represents a change in accounting principle. This guidance is effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity . In July 2015, the FASB issued new guidance on simplifying the measurement of inventory. This update requires a company to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective for the Company in the first quarter of fiscal 2018, and should be applied prospectively with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity . In September 2015, the FASB issued new guidance on business combination provisional adjustments during the measurement period. The new standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined and sets forth new disclosure requirements related to the adjustments. This guidance is effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In November 2015, the FASB issued new guidance on the presentation of deferred income taxes. This update requires a company to present deferred tax liabilities and assets as noncurrent in a classified statement of financial position rather than the current requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts. This guidance is effective for the Company in the first quarter of fiscal 2018, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity .

Fair Value Measurements [Abstract]
Fair Value Measurements	2 . Fair Value Measurements The Company estimates the fair value of assets and liabilities in accordance with the framework established by the authoritative guidance for fair value measurements. The framework is based on the inputs used in valuation, gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions. The level in the fair value hierarchy within which the fair value measurement is reported is based on the lowest level input that is significant to the measurement in its entirety. The three levels of the hierarchy are as follows: · Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date . · Level 2 – Inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data . · Level 3 – Unobservable inputs for the asset or liability used to measure fair value that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Financial assets measured at fair value on a recurring basis are summarized below: Fair Value Measurements at September 30, 2015 (Dollars in Thousands) Level 1 Level 2 Level 3 Asset Category Cash equivalents $ $ - $ - Mutual funds - - Available-for-sale securities - - Total Financial Assets at Fair Value $ $ $ - Fair Value Measurements at September 30, 2014 (Dollars in Thousands) Level 1 Level 2 Level 3 Asset Category Cash equivalents $ $ - $ - Mutual funds - - Available-for-sale securities - - Total Financial Assets at Fair Value $ $ $ - Following is a description of each category in the fair value hierarchy and the financial assets and liabilities of the Company that were included in each category at September 30, 201 5 and 201 4 , measured on a recurring basis. The Level 1 financial assets were comprised of investments in trading securities, which are reported in other long-term assets. The investments are held in a Rabbi trust for benefits under the Company’s deferred compensation plan. Under the plan, participants designate investment options to serve as the basis for measurement of the notional value of their accounts. The investments include a money market fund and mutual funds that are publicly traded. The fair values of the shares or underlying securities of these funds are based on quoted market prices. The Level 2 financial assets are long-term investments consisting primarily of fixed income mutual funds classified as available-for-sale secu rities. These investments are reported in other long-term assets. The investments in fixed income mutual funds are valued based on the net asset value of the underlying securities as provided by the investment account manager. The investments are not restricted or subject to a lockup and may be redeemed on demand. Notice within a certain period of time prior to redemption is not required. The Company’s long term debt is classified as Level 2. The carrying amount of the Company’s long-term debt approximated fair value as the stated interest rates were variable in relation to prevailing market rates. The Company recorded a liability for contingent consideration during the second quarter of fiscal 2014 related to the acquisition of ilumark and the launch of its new medical products. The liability was recorded at f air value , which was determined using a discounted cash flow model based on assumptions and pr ojections relevant to revenues. A discount rate of 11% was used and payments are projected to occur in fiscal 2016 and 2017. The contingent consideration liability is classified as Level 3. The Company had no material assets or liabilities that were measured at fair value on a non-recurring basis during the fiscal year ended September 30, 2015. As discussed in Not e 7, the C ompany completed an impairment test for Medical Products goodwill and long-lived assets as of June 30, 2014 when it became apparent that anticipated revenue and profitability trends in our IZI Medical Product s reporting un i t were not being achieved to the extent forecasted . There were no transfers between fair value hierarchy levels during these periods.

Disposition Of Business	4 . D isposition of Business The Company divested its radon business on September 30, 2015, and received cash proceeds of approximately $7.0 million, net of cash assumed by the acquirer and net of cash paid for transaction expenses. Approximately $0.7 million of transaction expenses were paid subsequent to the closing of the divestiture and were recorded in other accrued expenses on the Consolidated Balance Sheet as of September 30, 2015. The Company recognized a $1.0 million pre-tax gain on sale from the disposition of this business. In conjunction with this transaction, the Company released $1.4 million of foreign currency translation losses previously recorded in accumulated other comprehensive loss, resulting in a $0.4 million net loss on the disposition of business. The Company has evaluated whether this divestiture qualifies as a discontinued operation pursuant to FASB Accounting Standards Codification 205-20 “Discontinued Operations.” The Company has concluded that the transaction should not be reported as a discontinued operation and is not material to the Company’s financial results.

Income (Loss) Per Common Share [Abstract]
Income (Loss) Per Common Share	5. Income (Loss) per Common Share Basic net income (loss) per share was computed by dividing net income (loss) available to common stockholders for the period by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share was computed by dividing net income (loss) available to common stockholders for the period by the weighted average number of shares of common stock that would have been outstanding assuming dilution from stock-based compensation awards during the period. Unvested stock-based compensation awards that contain non-forfeitable rights to dividends are treated as participating securities and included in the computation of earnings per share pursuant to the two-class method. The Company’s time vested restricted stock is a participating security. The following table sets forth the computation of net income (loss) per share for the years ended September 30: (Dollars in Thousands, Except per Share) 2015 2014 2013 Basic Net Income (Loss) per Share: Net income (loss) attributed to Landauer, Inc. $ $ $ Less: Income allocated to unvested restricted stock - Net income (loss) available to common stockholders $ $ $ Basic weighted average shares outstanding Net income (loss) per share – Basic $ $ $ Diluted Net Income (Loss) per Share: Net income (loss) attributed to Landauer, Inc. $ $ $ Less: Income allocated to unvested restricted stock - Net income (loss) available to common stockholders $ $ $ Basic weighted average shares outstanding Effect of dilutive securities - Diluted weighted average shares outstanding Net income (loss) per share – Diluted $ $ $ In periods where losses are recorded, inclusion of potentially dilutive securities in the calculation would decrease the loss per common share and, therefore, these securities are not added to the weighted average number of shares outstanding. The computations of diluted net loss per common share for fiscal 2014 did not include the following outstanding shares of restricted stock as well as the effects of options to acquire common stock as the inclusion of these securities would have been antidilutive: 2015 2014 2013 Effect of dilutive securities - -

The Company has three segments: Radiation Measurement; Medical Physics; and Medical Products. The Company completed a quantitative assessment for the Radiation Measurement, Medical Physics and Medical Products reporting segments as of September 30, 2015 using the income approach and the market approach, and the estimated fair value of these reporting segments significantly exceeded their carrying values. The discount rates used in this valuation ranged from 11% to 13% . The accumulated impairment charge as of the beginning of the year and end of the year September 30, 2015 is $64.1 million as explained below. The Company completed an impairment test for the Medical Products segment as of June 30, 2014 when it became apparent that anticipated revenue and profitability trends in Medical Products were not being achieved to the extent forecasted. Based on the testing performed, the Company recorded a non-cash impairment charge of $62.2 million, of which $41.4 million related to goodwill and $20.8 million related to intangible assets for the fiscal year ended September 30, 2014. The tax benefit associated with the goodwill impairment charge was $15.3 million, and the tax benefit associated with the intangible assets charge was $7.7 million. During the third quarter of fiscal 2013, the Company performed an impairment analysis with respect to the carrying value of the goodwill in the Medical Products reporting unit. Based on the testing performed, the Company recorded a non-cash goodwill impairment charge of $22.7 million. The tax benefit associated with this charge was $8.5 million. Intangible assets for the years ended September 30 were as follows: 2015 (Dollars in Thousands) Gross Carrying Amount Accumulated Amortization Net Carrying Amount Accumulated Intangibles Impairment Charge Customer lists $ $ $ $ Trademarks and tradenames Licenses and patents Other intangibles - Intangible assets $ $ $ $ 2014 (Dollars in Thousands) Gross Carrying Amount Accumulated Amortization Net Carrying Amount Accumulated Intangibles Impairment Charge Customer lists $ $ $ Trademarks and tradenames Licenses and patents Other intangibles - Intangible assets $ $ $ $ The Company assumed customer lists relating to business combinations of $0 and $711 during fiscal 2015 and 2014, respectively.

Income Taxes	9 . Income Taxes The components of pretax income for the years ended September 30 were as follows: (Dollars in Thousands) 2015 2014 2013 Pretax income: U.S. $ $ $ Foreign Total pretax income $ $ $ The components of the provision for income taxes for the years ended September 30 were as follows: (Dollars in Thousands) 2015 2014 2013 Current: U.S. Federal $ $ $ State and local Foreign Current tax provision $ $ $ Deferred: U.S. Federal $ $ $ State and local Foreign Deferred tax provision $ $ $ Income tax provision $ $ $ The effective tax rates for the fiscal years ended September 30, 201 5 , 201 4 and 201 3 were 29.4% , 39.0% and (18.1%) , respectively. The decrease in the fiscal 2015 effective tax rate was primarily due to the retroactive enactment of the research and development credit for calendar year 2014 in the first fiscal quarter of 2015, the mix of earnings between jurisdictions with differing tax rates and the realization of an unrecognized tax benefit . The following is a reconciliation of the U.S. federal statutory rate of 35.0 % to the effective income tax rate: 2015 2014 2013 U.S. Federal statutory rate State and local taxes net of Federal tax benefit -4.9% Effect of foreign affiliates -4.4% -20.7% Earnings of unconsolidated affiliates -3.2% -26.4% R&D credit -0.4% -9.5% Domestic production activity deduction -0.8% -8.3% Partnership income -1.3% Provision to return adjustments -0.9% -0.4% -16.4% Meals and entertainment -0.3% Change in deferred rate Uncertain tax positions -1.6% -0.3% Other -0.8% Effective income tax rate -18.1% The tax effects of temporary differences that gave rise to deferred income tax assets and liabilities consisted of the following at September 30: (Dollars in Thousands) 2015 2014 Deferred tax assets: Pension accrual $ $ Compensation expense Transaction costs Medical insurance claims Retirement plans Accruals not currently deductible NOLs and attributes Intangible asset amortization Cumulative translation adjustment Other Deferred tax liabilities: Depreciation Software development Other Net deferred tax asset $ $ The Company believes that the realization of deferred tax assets is more likely than not based upon the expectation the Company will generate the necessary taxable income in the future periods. Therefore, no valuation allowances have been provided. The Company has provided for U.S. deferred income taxes and foreign withholding tax in the amount of $ 347 on undistributed earnings not considered permanently reinvested in its non-U.S. subsidiaries . The Company has no indefinite reinvested foreign earnings and profits . As of September 30, 201 5 , 201 4 and 201 3 , permanently reinvested cumulative undistributed earnings attributable to certain foreign operations were approximately $0 , $0 , and $13,085 , respectively. The change in the indefinitely reinvested cumulative undistributed earnings from fiscal 2013 to fiscal 2014 is due to the Company no longer asserting indefinite reinvestment of any foreign earnings and profits. As of September 30, 201 5 , the Company ’ s U.S. income tax returns for fiscal 201 3 and subsequent years remained subject to examination by the Internal Revenue Service ( “ IRS ” ). During fiscal 2015, the Company received a no change audit letter from the IRS officially closing the audit of fiscal 2012. State income tax returns generally have statute of limitations for periods between three and four years from the date of filing. The Company is currently undergoing a state income tax audit. The Company does not expect the audit to have a material impact on its consolidated financial statements. The Company is not currently under audit in any foreign jurisdictions. The Company’s foreign operations have statute of limitations on the examination of tax returns for periods between two and six years. The Company operates in numerous taxing jurisdictions and is subject to regular examinations by various U.S. federal, state, local and foreign jurisdictions for various tax periods. The Company’s income tax positions are based on research and interpretations of the income tax laws and rulings in each of the jurisdictions in which it does business. Due to the subjectivity of interpretations of the income tax laws and rulings in each jurisdiction, the differences and interplay in tax laws between those jurisdictions, as well as the inherent uncertainty in estimating the final resolution of complex tax audit matters, the Company’s estimates of income tax liabilities may differ from actual payments or assessments. Accounting for uncertainty in income taxes requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company records a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on its tax return. To the extent that the Company’s assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. A reconciliation of gross unrecognized tax benefits, exclusive of interest and penalties, is as follows: (Dollars in Thousands) 2015 2014 2013 Balance at beginning of year $ $ $ Tax positions related to current year: Gross increases Tax positions related to prior periods: Gross increases Decreases related to lapse of statute of limitations Balance at end of year $ $ $ The total amount of unrecognized tax benefits, net of federal benefit that, if recognized, would affect the effective tax rate was $1,274 , $ 1,840 and $ 1,362 , as of September 30, 201 5 , 201 4 and 201 3 , respectively. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. As of September 30, 201 5 and 201 4 , the gross amount of interest and penalties recorded was $316 and $ 375 , respectively. The Company’s unrecognized tax benefits are primarily due to intercompany allo cations between jurisdictions. The amount of unrecognized tax benefits and the related interest and penalties expected to reverse within the next fiscal year is estimated to be approximately $ 636.

Employee Benefit Plans [Abstract]
Employee Benefit Plans	1 2 . Employee Benefit Plans The Company sponsors postretirement benefit plans to provide pension, supplemental retirement funds, and medical expense reimbursement to eligible retired employees, as well as a directors’ retirement plan that provides for certain retirement benefits payable to non-employee directors. Following is a description of these benefit plans. Defined Contribution Plans The Company sponsors a 401(k) retirement savings plan covering substantially all Radiation Measurement U.S. full-time employees as well as substantially all of the employees of the Company’s Medical Physics and Medical Products segments. The Company also maintains a supplemental defined contribution plan for certain executives, which allows participating executives to make voluntary deferrals and provides for employer contributions at the Company ’s discretion. The plans are qualified under applicable sections of the Internal Revenue Code and allow employees to contribute a portion of their pre-tax income in accordance with specified guidelines. The Company matches a percentage of the employee contributions up to certain limits. Amounts expensed for Company contributions under these plans during the fiscal years ended September 30, 201 5 , 201 4 and 201 3 were $1,784 , $ 1,723 and $ 1,699 , respectively. Defined Benefit Plans Historically the Company provided, to substantially all full-time employees in the U.S., a qualified noncontributory defined benefit pension plan to provide a basic replacement income benefit upon retirement. For key executives, the basic benefit was augmented with a supplemental executive retirement plan to address U.S. tax law limitations placed on the benefits under the qualified pension plan. The supplemental plan is not separately funded and costs of the plan are expensed annually. The qualified noncontributory defined benefit pension plan and the supplemental executive retirement plan were frozen in fiscal 2009 and future benefit accruals under such plans ceased. The Company formerly maintained a directors ’ retirement plan that provide d certain retirement benefits for non-employee directors. The directors ’ plan was terminated in January 1997 and benefits accrued under the retirement plan we re frozen. The Company also maintains an unfunded retiree medical expense reimbursement plan. Under the terms of the plan, which covers retirees with ten or more years of service, the Company reimburses retirees to age 70, or to age 65 in accordance with plan changes effective October 1, 2005, for (i) a portion of the cost of coverage under the then-current medical and dental insurance plans if the retiree is under age 65, or (ii) all or a portion of the cost of Medicare and supplemental coverage if the retiree is over age 64. The assumptions for health-care cost ultimate trend rates were 6 % for those younger than 65, and 5 % for those 65 and older. The Company recognizes the over- or underfunded status of its defined benefit pension and postretirement plans on its balance sheet and recognizes changes in the funded status, as the changes occur, through comprehensive income. The Company uses its fiscal year end, September 30, as the measurement date for its plans. The following tables set forth the status of the combined defined benefit pension plans and the postretirement medical plan, as pension benefits and other benefits, respectively, at September 30. Pension Benefits Other Benefits (Dollars in Thousands) 2015 2014 2015 2014 Change in benefit obligation: Benefit obligation at beginning of year $ $ $ $ Service cost - - Interest cost Actuarial (gain) loss Benefits paid Benefit obligation at end of year Change in plan assets: Fair value of plan assets at beginning of year - - Actual return on plan assets - - Employer contributions Benefits paid Fair value of plan assets at end of year - - Funded status at end of year $ $ $ $ Pension Benefits Other Benefits (Dollars in Thousands) 2015 2014 2015 2014 Amounts recognized in consolidated balance sheets: Current liabilities – accrued pension and postretirement costs $ $ $ $ Noncurrent liabilities – pension and postretirement obligations Net amount recognized $ $ $ $ Amounts recognized in accumulated other comprehensive income (loss): Net loss (gain) $ $ $ $ Net amount recognized in accumulated other comprehensive income (loss) $ $ $ $ As of September 30, 201 5 and 201 4 , the accumulated benefit obligation for all defined benefit pension plans was $39,049 and $ 38,976 respectively. Information for pension plans with an accumulated benefit obligation in excess of plan assets as of September 30 is set forth in the following table: (Dollars in Thousands) 2015 2014 Projected benefit obligation $ $ Accumulated benefit obligation Fair value of plan assets The components of net periodic benefit cost that were amortized from Accumulated Other Comprehensive Income were as follows: Pension Benefits (Dollars in Thousands) 2015 2014 2013 Interest cost $ $ $ Expected return on plan assets Amortization of net loss Net periodic benefit cost $ $ $ Other Benefits (Dollars in Thousands) 2015 2014 2013 Service cost $ $ $ Interest cost Amortization of net gain Net periodic benefit cost $ $ $ Other changes in plan assets and benefit obligations recognized in other comprehensive income, pre-tax, were as follows: Pension Benefits (Dollars in Thousands) 2015 2014 2013 Net loss (gain) $ $ $ Amortization of net loss Total recognized in other comprehensive income (loss) Total recognized in net periodic benefit cost and other comprehensive income (loss) $ $ $ Other Benefits (Dollars in Thousands) 2015 2014 2013 Net (gain) loss $ $ $ Amortization of net gain Total recognized in other comprehensive income (loss) Total recognized in net periodic benefit cost and other comprehensive income (loss) $ $ $ The estimated pre-tax amount in accumulated other comprehensive income expected to be recognized in net periodic benefit cost over the next fiscal year for pension benefits is a net loss of $ 553 . The estimated pre-tax amount in accumulated other comprehensive income expected to be recognized in net periodic benefit cost over the next fiscal year for other benefits is a net gain of $ 39 . During fiscal 2014, the Company adopted the RP-2014 mortality tables and the Mortality Improvement Scale MP-2014 published by the Society of Actuaries’ Retirement Plans Experience Committee. The adoption of the updated mortality tables and the mortality improvement scale increased the Company’s pension liability more than $3 million. Assumptions The weighted-average discount rate used to determine benefit obligations at September 30, 2015 was 4.15% , 3.80% , 4.06% and 2.98% for Pension, Key Executive SERP, Manager SERP and Directors plans, respectively, which all fall under “Pension Benefits” in this footnote. The weighted-average discount rate used to determine benefit obligations under “Other Benefits” was 3.43% at September 30, 2015. The weighted-average assumptions used to determine net periodic benefit cost for years ended September 30 were as follows: Pension Benefits Other Benefits 2015 2014 2013 2015 2014 2013 Discount rate Expected long-term return on plan assets na na na Rate of compensation increase na na na na na na The expected long-term rate of return of plan assets is based on historical and projected rates of return for current and planned asset classes in the plan’s investment portfolio. Based on the target asset allocation for each asset class, the overall expected rate of return for the portfolio was developed and adjusted for historical and expected experience of the active portfolio management results compared to the benchmark returns and for the effect of expenses paid from plan assets. The Company reviews this long-term assumption on an annual basis. Assumed health care cost trend rates at September 30 were as follows: 2015 2014 Health care cost trend rate assumed for next year Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) Year that the rate reaches the ultimate trend rate Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in assumed health care cost trend rates would have the following effects as of September 30, 201 5 . (Dollars in Thousands) 1-Percentage- Point Increase 1-Percentage- Point Decrease Effect on aggregate of service and interest cost $ $ Effect on postretirement benefit obligation $ $ Contributions The Company, under IRS minimum funding standards, has no required contributions to make to its defined benefit pension plan during fiscal 201 6 . Estimated Future Benefit Payments The following benefit payments, which reflect expected future service as appropriate, are expected to be paid: (Dollars in Thousands ) Pension Benefits Other Benefits 2016 $ $ 2017 2018 2019 2020 Years 2021-2025 Plan Assets The Company’s pension plan weighted-average asset allocations by asset category at September 30 were as follows: Plan Assets at September 30, Asset Category: 2015 2014 Fixed income Equity securities Cash equivalents Total Plan assets for the qualified defined benefit pension plan include marketable equity securities, corporate and government debt securities, and cash and short-term investments. The plan assets are not directly invested in the Company’s common stock. The supplemental executive retirement plans and the directors’ retirement plan are not separately funded. The plan’s investment strategy supports the objectives of the plan. These objectives are to maximize returns in order to meet long-term cash requirements within reasonable and prudent levels of risk. To achieve these objectives, the Company has established a strategic asset allocation policy which is to maintain approximately one half of plan assets in high quality fixed income securities such as investment grade bonds and short - term government securities, with the other half containing large capitalization equity securities. The plan’s objective is to periodically rebalance its assets to approximate weighted-average target asset allocations. Investments are diversified across classes and within each class to minimize the risk of large losses. Additional information regarding fair value inputs and hierarchy is contained in N ote 2 . Plan assets measured at fair value on a recurring basis are summarized below: Fair Value Measurements at September 30, 2015 (Dollars in Thousands) (Level 1) (Level 2) (Level 3) Asset Category: Money market accounts $ $ - $ - Debt securities: Domestic - - International - - Equity securities: Domestic - - International - - Total assets at fair value $ $ - $ - Fair Value Measurements at September 30, 2014 (Dollars in Thousands) (Level 1) (Level 2) (Level 3) Asset Category: Money market accounts $ $ - $ - Debt securities: Corporate bonds - - Government bonds - - Equity securities: Domestic - - International - - Total assets at fair value $ $ - $ -

Segment Information [Abstract]
Segment Information	1 6 . Segment Information During fiscal 2014, t he Company changed the presentation of its reporting segments to separately disclose certain ‘corporate expenses’ that had previously been reported within the Radiation Measurement segment. As a result, the current segment disclosures reflect three reporting segments ( Radiation Measurement, Medical Physics and Medical Products ) and one functional group ( Corporate ) . The factors for determining the reportable segments reflect specific markets and the products and services offered combined with the nature of the individual business traits, as well as key financial information reviewed by management. The Radiation Measurement segment provides analytical services to determine occupational and environmental radiation exposure. These services are provided internationally primarily to hospitals, medical and dental offices, universities, national laboratories, and nuclear facilities. Radiation Measurement activities include the manufacture of various types of radiation detection monitors, the distribution and collection of the monitors to and from customers, and the analysis and reporting of exposure findings. In addition to providing analytical services, the Radiation Measurement segment sells dosimetry detectors and reading equipment. The Medical Physics segment provides therapeutic and imaging physics services to domestic hospitals and radiation therapy centers. Service offerings include clinical physics support, equipment commissioning, accreditation support and imaging equipment testing. These professional services are provided to customers on-site by skilled physicists. The Medical Products segment provides medical consumable accessories used in radiology, radiation therapy, and image guided surgery procedures. Medical products range from consumables used with MRI, CT, and mammography technologies to highly engineered passive reflective markers used during image guided surgery procedures. The Company primarily evaluates performance of the individual segments based upon, among other metrics, segment operating income or loss. Segment operating income or loss is segment revenues less segment cost of sales and segment selling, general and administrative expenses. Corporate expenses for shared functions, including corporate management, corporate finance and human resources, are recognized in the Corporate functional group. In addition, acquisition and reorganization costs are not allocated to the segments. Information about net other income, including interest income and expense, and income taxes is not provided at the segment level. As the Company’s business model evolves in increased complexity, management may determine it necessary to change this reporting practice to reflect any appropriate allocations.

Summary Of Significant Accounting Policies [Abstract]
Description of Business	Description of Business Landauer, Inc., together with the subsidiaries through which businesses are conducted (the “Company”), is a leading global provider of technical and analytical services to determine occupational and environmental radiation exposure, the leading domestic provider of outsourced medical physics services, and a provider of radiology related medical products. The Company operates in three primary business segments: Radiation Measurement; Medical Physics; and Medical Products. Additional information regarding the Company’s segments is contained in Note 1 6 .
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of the Company, its subsidiaries and variable interest entities in which the Company has a controlling financial interest. All intercompany balances and transactions have been eliminated in consolidation. Entities in which the Company does not have a controlling financial interest, but is considered to have significant influence, are accounted for on the equity method.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all unrestricted cash and highly liquid investments with an original maturity of three months or less, primarily short-term money market instruments.
Restricted Cash	Restricted Cash Restricted cash represents funds that are restricted to satisfy designated current liabilities. As of September 30, 2014, the Company’s restricted cash represented deposits from an international customer that were held from the Company subject to the achievement of specified conditions. This balance was included in “Other current assets.” The Company successfully fulfilled the conditions in October 2014 and the funds were released and no longer restricted.
Receivables, Net of Allowances	Receivables, Net of Allowances Receivables, principally trade accounts receivable, are generally due within 30 to 90 days and are stated at amounts due from customers, net of an allowance for sales returns and doubtful accounts. The Company performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness, as determined by a review of their current credit information. We continuously monitor aging reports, collections and payments from customers, and a provision for estimated credit losses is maintained based upon the Company’s historical experience and any specific customer collection issues that have been identified. While such credit losses have historically been within our expectations and the provisions established, we cannot guarantee that the same credit loss rates will be experienced in the future. The Company writes off accounts receivable when they are determined to be uncollectible.
Inventories	Inventories Inventories primarily include the components associated with dosimetry devices, which are stated at lower of cost or market utilizing a first-in, first-out method.
Long-lived Assets	Long-lived Assets Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Plant, equipment and internal use software are depreciated on a straight-line basis over their respective estimated useful lives. Dosimetry devices, principally badges, and the accompanying software are amortized on a straight-line basis over their estimated useful lives. Expenditures for maintenance and repairs are charged to expense as incurred, and renewals and betterments are capitalized. The following table provides a summary of estimated useful lives by asset category: Estimated Useful Lives Buildings and improvements 30 years Internal software 5 - 10 years Equipment 3 - 8 years Dosimetry devices 30 months - 8 years Long-lived assets, including definite-lived intangible assets, are reviewed for impairment whenever events or changes in business circumstances indicate that the carrying value of the assets may not be fully recoverable. The Company performs undiscounted operating cash flow analyses to determine if an impairment exists. For purposes of recognition and measurement of an impairment for assets held for use, the Company groups assets and liabilities at the lowest level for which cash flows are separately identifiable. If an impairment is determined to exist, any related impairment loss is calculated based on fair value. Impairment losses on assets to be disposed of, if any, are based on the estimated proceeds to be received, less costs of disposal. The Company also reviews the estimated remaining useful lives of long-lived assets whenever events or changes in business circumstances indicate the lives may have changed.
Equity in Joint Ventures	Equity in Joint Ventures Entities in which the Company does not have a controlling financial interest but is considered to have significant influence are accounted for on the equity method. Under the equity method, a company records its share of net income or loss of an investment based on its percentage ownership. Additional information regarding the Company’s equity in joint ventures is contained in Note 6 .
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and other indefinite-lived intangible assets must be assessed for impairment annually or more frequently if events or changes in circumstances indicate that such assets might be impaired. Triggering events include, but are not limited to a current period operating or cash flow loss; a product, technology or service introduced by a competitor; or a loss of key personnel. Goodwill impairment testing first requires a comparison between the carrying value and fair value of a reporting unit with associated goodwill. Carrying value is based on the assets and liabilities associated with the operations of that reporting unit. The Company estimates the fair value of the reporting units using the income approach and the market approach. If the Company believes that the fair value of a reporting unit exceeds its carrying value by a substantial margin, the Company may perform a qualitative analysis instead. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not to be impaired and the second step of the impairment test is unnecessary. If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination, and the fair value of the reporting unit was the purchase price paid to acquire the segment. The impairment test for an indefinite-lived intangible asset other than goodwill consist s of first assessing qualitative factors, such as company, industry and economic trends. If determined to be necessary, the next step compares the fair value of the intangible asset to its carrying amount. If the carrying amount exceeds the fair value, an impairment loss is recognized for the difference. Additional information regarding the Company’s goodwill and other intangible assets is contained in Note 7 .
Long-term Investments	Long-term Investments The Company had long-term investments of $3,509 and $3,734 at September 30, 2015 and 2014, respectively that are held in a Rabbi trust for benefits under the Company’s deferred compensation plan. Under the plan, participants designate investment options to serve as the basis for measurement of the notional value of their accounts. The investments, classified as trading securities, include a money market fund and mutual funds that are publicly traded. Trading securities are carried at fair value with unrealized gains and losses included in earnings. The fair values of the shares or underlying securities of these funds are based on quoted market prices. The Company had long-term investments of $1,763 and $2,382 at September 30, 2015 and 2014, respectively, consisting of fixed income mutual funds classified as available-for-sale securities. Available-for-sale securities are carried at fair value with unrealized gains and losses, net of tax, reported in other comprehensive income. The cost of securities sold is based on the specific identification method. The investments are valued based on the net asset value of the underlying securities as provided by the investment account manager. The investments are not restricted or subject to a lockup and may be redeemed on demand. Notice within a certain period of time prior to redemption is not required. Long-term investments are included in other long-term assets.
Revenue Recognition and Deferred Contract Revenue	Revenue Recognition and Deferred Contract Revenue The majority of the Radiation Measurement revenues are realized from radiation measurement services and other services incidental to radiation dose measurement. The measuring and monitoring services provided by the Company to its customers are of a subscription nature and are continuous. The Company views its business in the Radiation Measurement segment as services provided to customers over a period of time and the wear period is the period over which those services are provided. Badge production, wearing of badges, badge analysis, and report preparation are integral to the benefit that the Company provides to its customers. These services are provided to customers on an agreed-upon recurring basis (monthly, bi-monthly, quarterly, semi-annually or annually) that the customer chooses for the wear period. Revenue is recognized on a straight-line basis, adjusted for changes in pricing and volume, over the wear period. Revenues are recognized over the periods in which the customers wear the badges irrespective of whether invoiced in advance or in arrears. Many customers pay for these services in advance. The amounts recorded as deferred contract revenue in the consolidated balance sheets represent customer deposits invoiced in advance during the preceding twelve months for services to be rendered over the succeeding twelve months, and are net of services rendered through the respective consolidated balance sheet date. Management believes that the amount of deferred contract revenue fairly represents the remaining business activity with customers invoiced in advance. Other services incidental to measuring and monitoring augment the basic radiation measurement services that the Company offers, providing administrative and informational tools to customers for the management of their radiation detection programs. Other service revenues are recognized upon delivery of the reports to customers or as other such services are provided. The Company sells radiation measurement products to its customers, principally InLight products, for their use in conducting radiation measurements or managing radiation detection programs. The Company recognizes Radiation Measurement segment product revenues upon shipment or delivery of goods when title and risk of loss pass to customers. The Company, through its Medical Physics segment, offers full scope medical physics services to hospitals and radiation therapy centers. Services offered include, but are not limited to, clinical physics support in radiation oncology, commissioning services, special projects support and imaging physics services. Delivery of the medical physics services can be of a contracted, recurring nature or as a discrete project with a defined service outcome. Recurring services often are provided on the customer’s premises by a full-time employee or fraction of a full-time employee. Revenue is recognized for recurring services on a straight-line basis over the life of the contract unless there is another discernable pattern as the services are rendered. Revenue is recognized for fee for service projects when the service is delivered. Contracted services are billed on an agreed-upon recurring basis, either in advance or arrears of the service being delivered. Customers may be billed monthly, quarterly, or at some other regular interval over the contracted period. The amounts recorded as deferred contract revenue represent amounts invoiced in advance of delivery of the service. Management believes that the amount of deferred contract revenue fairly represents remaining business activity with customers invoiced in advance. Fee for service revenue is typically associated with much shorter contract periods, or with discrete individual projects, and revenue is recognized upon completion of the project and customer acceptance thereof. Additional medical physics services under the full scope offering of the medical physics practice groups comprising the Medical Physics segment include radiation center design and consulting, accreditation work and quality assurance reviews. The Company, through its Medical Products segment, offers high quality medical consumable accessories used in radiology, radiation therapy, and image guided surgery procedures. The Medical Products segment recognizes revenues upon shipment or delivery of goods when title and risk of loss pass to customers. The amounts recorded as deferred contract revenue in the consolidated balance sheets represent invoiced amounts in advance of delivery of the service, and are net of services rendered through the respective consolidated balance sheet date. Deferred contract revenue was $13,904 and $14,750 , respectively, as of September 30, 2015 and 2014. Concentrations of credit risk with respect to accounts receivable are limited due to the high credit quality of the Company’s major customers, as well as the large number and geographic dispersion of smaller customers. The large diversified customer base results in no single customer representing greater than 5% of revenue. The Company routinely reviews outstanding customer balances and records allowances for bad debts as necessary.
Research and Development	Research and Development The cost of research and development programs is charged to selling, general and administrative expense as incurred and amounted to $4,579 , $ 5,813 and $ 4 ,121 in fiscal 2015, 2014 and 2013, respectively. Research and development costs include salaries and allocated employee benefits, third-party research contracts and supplies.
Advertising	Advertising The Company expenses the costs of advertising as incurred. Advertising expense, primarily related to product shows and exhibits, amounted to $1,023 , $ 1,191 and $ 1,339 in fiscal 2015, 2014 and 2013, respectively .
Income Taxes	Income Taxes The Company files income tax returns in the jurisdictions in which it has sufficient presence. The Company estimates the income tax provision for income taxes that are currently payable, and records deferred income tax assets and liabilities for the temporary differences in tax consequences between the financial statements and tax returns. The Company records a valuation allowance in situations where the realization of deferred income tax assets is not more likely than not. The Company recognizes the financial statement effects of its tax positions in its current and deferred income tax assets and liabilities when it is more likely than not that the position will be sustained upon examination by a taxing authority. Additional information regarding the Company’s income taxes is contained in Note 9 .
Stock-Based Compensation	Stock-Based Compensation The Company measures and recognizes compensation cost at fair value for all share-based payments, including stock options. The Company has not granted stock options subsequent to fiscal 2005. Awards of stock options in prior fiscal years were granted with an exercise price equal to the market value of the stock on the date of grant. The fair value of stock options was estimated using the Black-Scholes option-pricing model. Expected volatility and the expected life of stock options were based on historical experience. The risk free interest rate was derived from the implied yield available on U.S. Treasury zero-coupon issues with a remaining term, as of the date of grant, equal to the expected term of the option. The dividend yield was based on annual dividends and the fair market value of the Company’s stock on the date of grant. Compensation expense was recognized ratably over the vesting period of the stock option. Subsequent to fiscal 2005, key employees and/or non-employee directors have been granted restricted share awards that consist of performance shares and time vested restricted stock. Performance shares represent a right to receive shares of common stock upon satisfaction of performance goals or other specified metrics. Restricted stock represents a right to receive shares of common stock upon the passage of a specified period of time. Upon the adoption of the Company’s Incentive Compensation Plan in February 2008, the fair value of performance shares and restricted stock granted under the new plan is based on the Company’s closing stock price on the date of grant. Compensation expense for performance shares is recorded ratably over the vesting period, assuming that achievement of performance goals is deemed probable. Compensation expense for restricted stock is cliff vested and recognized ratably over the vesting period. The Company also retains the discretion to make additional awards to executives at other times for recruiting or retention purposes. Stock-based compensation for these awards can be either cliff or graded vested depending on the agreement, and recognized ratably over the vesting period. Forfeitures of awards are estimated at the time of grant and stock-based compensation cost is recognized only for those awards expected to vest. The Company uses historical experience to estimate projected forfeitures. The Company recognizes the cumulative effect on current and prior periods of a change in the forfeiture rate, or actual forfeitures, as compensation cost or as a reduction of cost in the period of the revision.
Foreign Currency Translation	Foreign Currency Translation Financial statements of foreign subsidiaries are translated into U.S. dollars using period-end exchange rates for assets and liabilities and weighted-average exchange rates for revenues and expenses. Adjustments resulting from translating net assets are reported as a separate component of accumulated other comprehensive loss within common shareholders’ equity as currency translation adjustment.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adoption of Accounting Standards Updates In April 2014, the Financial Accounting Standards Board (“FASB”) issued revised guidance to reduce the diversity in presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. This requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred income tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions listed in the guidance. This guidance was adopted by the Company in the first quarter of fiscal 2015. The adoption of this guidance did not have a material impact on the Company’s results of operations, financial position and liquidity. In November 2014, the FASB issued new guidance on accounting for pushdown accounting in the event of a business combination. This update provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. This guidance was adopted by the Company in the first quarter of fiscal 2015. The adoption of this guidance did not have a material impact on the Company’s results of operations, financial position and liquidity. In April 2014, the FASB issued new guidance related to the definition of a discontinued operation and requires new disclosure of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. This new guidance is effective for annual periods beginning on or after December 15, 2014 and interim periods within those years. The Company early adopted this guidance beginning in the fourth quarter of fiscal 2015. The adoption of this guidance did not have a material impact on the Company’s results of operations, financial position and liquidity. Accounting Standards Not Yet Adopted In May 2014, the FASB issued new guidance for recognizing revenue from contracts with customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. In July 2015, the FASB deferred the effective date of the new revenue standard by one year. Public companies would now be required to adopt the new guidance for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The FASB decided to allow earlier adoption of the new revenue standard, but not earlier than the original effective date. This guidance is effective for the Company in the first quarter of fiscal 2019. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In June 2014, the FASB issued new guidance on accounting for share-based payments requiring a specific performance target to be achieved in order for employees to become eligible to vest in the awards when that performance target may be achieved after the requisite service period for the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period for which the requisite service has already been rendered. This guidance is effective for the Company in the first quarter of fiscal 2017. Early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In August 2014, the FASB issued new guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of doubt about the entity’s ability to continue as a going concern. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. This guidance will be effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity. In January 2015, the FASB issued new guidance on accounting for unusual and infrequently occurring items, which eliminates the concept of extraordinary items. An unusual and infrequently occurring item will no longer be classified as an extraordinary item and segregated from ordinary operations in the income statement, but will be shown as a component of income from continuing operations or separately disclosed in notes to the financial statements. This guidance is effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity. In February 2015, the FASB issued amended guidance on the model used to evaluate whether certain legal entities should be consolidated. This guidance is effective for the Company in the first quarter of fiscal 2017. Early adoption is permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In April 2015, the FASB issued new guidance on the presentation of debt issuance costs. This update requires a company to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with the presentation of debt discounts. Currently, debt issuance costs are presented as a deferred asset. The recognition and measurement requirements will not change as a result of this guidance. The update requires retrospective application and represents a change in accounting principle. This guidance is effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity . In July 2015, the FASB issued new guidance on simplifying the measurement of inventory. This update requires a company to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective for the Company in the first quarter of fiscal 2018, and should be applied prospectively with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity . In September 2015, the FASB issued new guidance on business combination provisional adjustments during the measurement period. The new standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined and sets forth new disclosure requirements related to the adjustments. This guidance is effective for the Company in the first quarter of fiscal 2017, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its results of operations, financial position and liquidity. In November 2015, the FASB issued new guidance on the presentation of deferred income taxes. This update requires a company to present deferred tax liabilities and assets as noncurrent in a classified statement of financial position rather than the current requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts. This guidance is effective for the Company in the first quarter of fiscal 2018, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its results of operations, financial position and liquidity .
