Basis Of Presentation And Consolidation [Abstract]
Basis Of Presentation And Consolidation	(1) Basis of Presentation and Consolidation  As used herein, the terms “Company,” “Landauer,” “we,” “us,” and “our” refer collectively to Landauer, Inc. and its subsidiaries through which its various businesses are conducted.  The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements.  The consolidated financial statements 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.  The preparation of the interim consolidated 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 interim consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  We believe that we have included all normal recurring adjustments necessary for a fair presentation of the results for the interim period. Operating results for the three and nine months ended June 30 , 201 7 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 201 7 .  These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 201 6 (the “Form 10-K”) and other financial information filed with the Securities and Exchange Commission (the “SEC”). The September 30, 201 6 balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP.  The accounting policies followed by the Company are set forth in the Form 10-K, and there have been no changes to the accounting policies for the nine-month period ended June 30, 2017 .  

Recent Accounting Pronouncement

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	(2) Recent Accounting Pronouncements  Accounting Standards Adopted  In June 2014, the Financial Accounting Standards Board (“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. The Company adopted the updated standard in the first quarter of fiscal 2017 with no significant impact on its financial statements.  In April 2015, the FASB issued new guidance on a customer’s accounting for fees paid in a cloud computing arrangement (“CCA”). Under the new standard, customers will apply the same criteria as vendors to determine whether a CCA contains a software license or is solely a service contract. The Company adopted the updated standard prospectively in the first quarter of fiscal 2017 with no significant impact on its financial statements.  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 that adoption of this guidance will have on its results of operations, financial position and liquidity. To date, the Company has formed a committee to evaluate the impact and is in the initial stages of evaluation.  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 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.  In February 2016, the FASB issued new guidance on the accounting treatment for leases. This guidance will require all leases with durations greater than twelve months to be recognized on the balance sheet of the lessee. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. This guidance is effective for the Company in the first quarter of fiscal 2020, although early adoption is permitted. The Company is currently evaluating the impact that adoption of this guidance will have on its results of operations, financial position and liquidity.  In March 2016, the FASB issued new guidance to improve the accounting for share-based payments. This standard makes several modifications to Topic 718 related to the accounting for forfeitures, employer tax withholding on share-based compensation and the financial statement presentation of excess tax benefits or deficiencies. The guidance also clarifies the statement of cash flows presentation for certain components of share-based awards. The standard is effective for the Company in the first quarter of fiscal 2018, although early adoption is permitted. The Company is currently evaluating the impact that adoption of this guidance will have on its results of operations, financial position and liquidity.  In June 2016, the FASB issued new guidance to introduce a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The update is effective for the Company in the first quarter of fiscal 2020, although early adoption is permitted. The Company is currently evaluating the effect that this update will have on its financial statements and related disclosures.  In August 2016, the FASB issued an Accounting Standards Update (“ASU”) to provide cash flow statement guidance for certain cash receipts and payments, including (a) debt prepayment or extinguishment costs; (b) contingent consideration payments made after a business combination; (c) insurance settlement proceeds; (d) distributions from equity method investees; (e) beneficial interests in securitization transactions and (f) application of the predominance principle for cash receipts and payments with aspects of more than one class of cash flows. The update is effective for the Company i n the first quarter of fiscal 2018. The Company is currently evaluating the effect that this update will have on its financial statements and related disclosures.  In November 2016, the FASB issued amendments to current guidance related to the classification and presentation of changes in restricted cash in the Statement of Cash Flows. The update is effective for the Company in the first quarter of fiscal 2019, and early adoption is permitted. The Company is currently evaluating the impact that this update will have on its financial statements and related disclosures.  No other new accounting pronouncement issued or effective during the fiscal year had, or is expected to have, a material impact on the Consolidated Financial Statements.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	(3) Fair Value Measurements  The Company estimate s 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 int o 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 t he 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 – I nputs 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 June 30, 2017  (Dollars in Thousands) Level 1 Level 2 Level 3  Asset Category  Cash equivalents $ 554 $ - $ -  Mutual funds 4,397 - -  Total financial assets at fair value $ 4,951 $ - $ -   Fair Value Measurements at September 30, 2016  (Dollars in Thousands) Level 1 Level 2 Level 3  Asset Category  Cash equivalents $ 453 $ - $ -  Mutual funds 3,687 - -  Total financial assets at fair value $ 4,140 $ - $ -  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 June 30, 2017 and September 30, 2016, 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 Company’s long-term debt is classified as Level 2. The carrying amount of the Company’s long-term debt is the approximated fair value, as the stated interest rates were variable in relation to prevailing market rates.

Income Taxes [Abstract]
Income Taxes	(8) Income Taxes  The effective tax rates for the three months ended June 3 0 , 2017 and 2016 were 27.5% and 31.3% , respectively. The de crease in the effective tax rate was primarily due to the mix of taxable earnings between jurisdictions with differing tax rates and the release of uncertain tax positions relative to pretax earnings. The effective tax rates for the nine months ended June 30 , 2017 and 2016 were 32.5% and 31.2% , respectively. The increase in the effective tax rate was primarily due to the mix of earnings between jurisdictions with differing tax rates and tax law changes that impacted the timing of recognition of certain credits in the prior year. The Company believes it is reasonably possible that $135 of unrecognized tax benefits will be realized in fiscal year 201 8.
