SECOND FISCAL QUARTER FINANCIAL OVERVIEW AND BUSINESS SEGMENT RESULTS

Revenues for the second fiscal quarter of 2011 were $32.3 million, a 2
percent increase compared with the $31.8 million reported for the second
fiscal quarter of 2010.  Cost of sales for the second fiscal quarter of
2011 were $11.6 million, a 2 percent decrease compared with the $11.8
million reported for the second fiscal quarter of 2010.  The gross margin
increased to 64 percent from 63 percent in the year ago period.  Selling,
general and administrative costs for the second fiscal quarter of 2011 were
$8.7 million, a 4 percent increase compared with the $8.4 million reported
for the second fiscal quarter of 2010.

Operating income for the second fiscal quarter of 2011 was $11.9 million, a
4 percent increase compared with operating income of $11.4 million for
fiscal 2010.  Other income for the second fiscal quarter increased 18
percent to $0.5 million.

The effective tax rate was 34.6% and 33.6% for the second fiscal quarter of
2011 and 2010, respectively.  Net income for the second fiscal quarter
ended March 31, 2011 was $8.0 million, an increase of 2 percent compared
with $7.8 million for the second fiscal quarter of 2010.  The resulting
diluted earnings per share for the second fiscal quarter of 2011 were $0.85
compared with $0.83 for the second fiscal quarter of 2010.  Earnings before
interest, taxes, depreciation and amortization ("EBITDA") were $14.2
million, a 7 percent increase compared with $13.3 million a year ago.  The
increase was due primarily to revenue growth, lower product costs based on
revenue mix and favorable equity earnings of joint ventures for the second
fiscal quarter of 2011.  A reconciliation of net income to EBITDA is
included in the attached financial exhibits.

RADIATION MONITORING SEGMENT

Radiation Monitoring revenues for the second fiscal quarter of 2011
declined 3 percent, or $0.8 million, to $27.5 million.  Of the decline,
$0.7 million is due to the previously reported change in the supply
relationship between Landauer and Nagase Landauer, which converted its
customer base from Luxel to the InLight technology during fiscal 2010.
Nagase Landauer no longer purchases service badges from the Company.  The
historical Luxel badge revenues were partially replaced by a royalty
arrangement, resulting in no corresponding impact on net income.  Without
the Nagase Landauer impact, domestic Radiation Monitoring revenues declined
6 percent, or $1.2 million, driven by lower non-recurring InLight equipment
sales, primarily to the Canadian government agency responsible for
occupational monitoring and radiation emergency preparedness for the
citizens of Canada.  International Radiation Monitoring revenues increased
14 percent, or $1.0 million, on organic growth in most regions and the
strengthening of most foreign currencies against the dollar.

Radiation Monitoring gross margin for the second fiscal quarter of 2011
increased to 71 percent from 68 percent in the year ago period, primarily
due to the decline in lower margin sales to Nagase Landauer.  Selling,
general and administrative costs for the second fiscal quarter of 2011
increased 3 percent, or $0.2 million, to $7.4 million.  The increase is due
primarily to the strengthening of most foreign currencies against the
dollar.  Operating income, inclusive of the impact of acquisition related
transaction and reorganization costs, for the second fiscal quarter of 2011
increased 2 percent, or $0.2 million, to $12.1 million compared with
operating income of $11.9 million for fiscal 2010.

MEDICAL PHYSICS SEGMENT

Medical Physics revenues for the second fiscal quarter of 2011 increased 40
percent, or $1.4 million, to $4.8 million on $0.7 million of organic growth
and $0.7 million due to the impact of acquired companies.  The gross margin
increased to 23 percent from 22 percent in the year ago period.  Selling,
general and administrative costs for the second fiscal quarter of 2011
increased 11 percent, or $0.1 million, to $1.3 million due to the
annualized impact of acquired companies.  Operating loss for the second
fiscal quarter of 2011 was $0.2 million, compared with an operating loss of
$0.4 million for fiscal 2010.

FISCAL SIX MONTHS FINANCIAL OVERVIEW AND BUSINESS SEGMENT RESULTS

Revenues for the first six months of fiscal 2011 were $60.8 million, a 3
percent increase compared with the $59.0 million reported for the same
period in fiscal 2010.  Cost of sales for the first six months of fiscal
2011 were $22.7 million, a 3 percent increase compared with the $22.0
million reported for the same period in fiscal 2010.  Gross margins were 63
percent each for the first half of fiscal 2011 and 2010, respectively.
Selling, general and administrative costs for the first six months of
fiscal 2011 were $17.9 million, a 10 percent increase compared with the
$16.2 million reported for the same period in fiscal 2010.

In conjunction with Landauer's acquisition activity, the Company incurred
$0.2 million and $1.7 million ($1.2 million, after-tax) of acquisition
related transaction and reorganization costs for the first six months of
fiscal 2011 and 2010, respectively.  Operating income for the six months
ended March 31, 2011 was $20.0 million, a 4 percent increase compared with
operating income of $19.2 million for the same period in fiscal 2010.
Other income for the first six months of fiscal 2011 increased 19 percent
to $1.1 million.

The effective tax rate was 33.2% and 34.8% for the first half of fiscal
2011 and 2010, respectively.  The decline in effective tax rate was due
primarily to the realization of R&D tax credits in fiscal 2011 recognized
with the passage of tax legislation in December 2010 and the
non-deductibility of certain acquisition related costs in fiscal 2010.  Net
income for the six months ended March 31, 2011 was $13.8 million, an
increase of 7 percent compared with $12.9 million for the six months ended
March 31, 2010.  The resulting diluted earnings per share for the first
half of fiscal 2011 were $1.47 compared with $1.38 for the same period in
fiscal 2010.  Earnings before interest, taxes, depreciation and
amortization ("EBITDA") were $24.4 million, a 6 percent increase compared
with $23.0 million a year ago.  The increase is due primarily to the $1.4
million reduction in acquisition related transaction and reorganization
costs for the first half of fiscal 2011.  A reconciliation of net income to
EBITDA is included in the attached financial exhibits.

RADIATION MONITORING SEGMENT

Radiation Monitoring revenues for the first six months of fiscal 2011
declined 4 percent, or $2.0 million, to $51.4 million.  Of the decline,
$2.1 million is due to the previously reported change in the supply
relationship between Landauer and Nagase Landauer, the Company's
unconsolidated joint venture in Japan.  Without the Nagase Landauer impact,
domestic Radiation Monitoring revenues declined 4 percent, or $1.4 million,
and international Radiation Monitoring revenues increased 11 percent, or
$1.5 million, on organic growth in most regions and the strengthening of
most foreign currencies against the dollar.

LANDAUER, INC. - ADD 3


Radiation Monitoring gross margin for the six months ended March 31, 2011
increased to 70 percent from 67 percent in the year ago period, primarily
due to the decline in lower margin sales to Nagase Landauer.  Selling,
general and administrative costs for the first six months of fiscal 2011
increased 5 percent, or $0.8 million, to $15.1 million.  The increase is
due primarily to costs to replace the Company's IT systems and increased
spending to support international revenue growth.  Operating income,
inclusive of the impact of acquisition related transaction and
reorganization costs, for the six months ended March 31, 2011 increased 4
percent, or $0.9 million, to $20.7 million compared with operating income
of $19.8 million for the same period in fiscal 2010.

MEDICAL PHYSICS SEGMENT

Medical Physics revenues for the first six months of fiscal 2011 increased
67 percent, or $3.8 million, to $9.3 million on $1.4 million of organic
growth and $2.4 million due primarily to the annualized impact of acquired
companies.  The gross margin was 23 percent each for the first six months
of fiscal 2011 and in the year ago period.  Selling, general and
administrative costs for the first six months of fiscal 2011 increased 46
percent, or $0.9 million, to $2.8 million.  The increase is due to the
impact of acquired companies.  Operating loss for the six months ended
March 31, 2011 was $0.7 million, compared with an operating loss of $0.6
million for the same period in fiscal 2010.

SOLID FINANCIAL POSITION

Landauer ended the second fiscal quarter of 2011 with total assets of
$157.1 million.  Due to the current liability classification of $18.3
million in outstanding borrowings incurred to support the acquisitions
completed during the first fiscal quarter of 2010, the Company had negative
working capital of $5.0 million.  The Company believes projected operating
cash flow and available borrowing under its current credit arrangements
provide adequate liquidity to meet its current and anticipated obligations.

Cash provided by operating activities for the six months ended March 31,
2011 was $16.9 million, an increase of $7.1 million from the first half of
fiscal 2010 due primarily to the changes in the components of working
capital.

FISCAL 2011 OUTLOOK

Landauer's current business plan for fiscal 2011 anticipates consolidated
revenue for the year to be in the range of $120 to $126 million, including
$4 to $8 million in sales to the U.S. military and first responder markets.

Military and first responder market sales are dependent on military and
other governmental appropriations and approvals which have yet to be
obtained.  There can be no assurance that such appropriations and approvals
can be obtained in fiscal 2011 or that orders will result immediately
following any such appropriation or approval.  The business plan
anticipates spending of $10 to $12 million to support the completion of the
Company's systems initiative, with $2 to $3 million being expensed in the
current fiscal year.  Based upon the above assumptions, the Company
anticipates reported net income for fiscal 2011 in the range of $24 to $26
million.

USE OF NON-GAAP FINANCIAL MEASURES

In evaluating the Company's financial performance and outlook, management
uses EBITDA.  EBITDA is a non-GAAP measure.  Management believes that such
measure supplements evaluations using operating income, net income, and
diluted earnings per share and other GAAP measures, and is a useful
indicator for investors.  This indicator can help readers gain a meaningful
understanding of our core operating results and future prospects without
the effect of non-cash items and the Company's ability to generate cash
flows from operations that are available for taxes, capital expenditures,
and debt repayment.  Investors should recognize that these non-GAAP
measures might not be comparable to similarly titled measures of other
companies.  These measures should be considered in addition to, and not as
a substitute for or superior to, any measure of performance, cash flows or
liquidity prepared in accordance with accounting principles generally
accepted in the United States.
