RECORD RESULTS DRIVEN BY BALANCED PERFORMANCE

Revenues for the second fiscal quarter of 2010 were $31.8 million, a 28
percent increase compared with the $25.0 million reported for the second
fiscal quarter of 2009.  Domestic revenue increased 23 percent, or $4.3
million, on contribution from Global Physics Solutions of $3.4 million and
InLight product revenues.  International revenue increased 44 percent, or
$2.5 million, due to contributions from acquired companies of $1.8 million,
organic growth and the strengthening of most foreign currencies against the
dollar.

Cost of sales for the second fiscal quarter of 2010 was $11.8 million, a 41
percent increase compared with the $8.4 million reported for the second
fiscal quarter of 2009.  The primary factor contributing to the increase
was $3.2 million of increased cost from acquired companies. The gross
margin declined to 63 percent from 66 percent in the year ago period,
primarily due to the lower margin contribution of the Medical Physics
segment.   Selling, general and administrative costs for the second fiscal
quarter of 2010 were $8.4 million, a 26 percent increase compared with the
$6.7 million reported for the second fiscal quarter of 2009. The primary
factor contributing to the increase was approximately $1.5 million of
increased spending from acquired companies.

During the second quarter of fiscal 2009, the Board of Directors approved
changes to the Company's retirement benefit plans to transition from a
defined benefit philosophy for retirement benefits to a defined
contribution approach.  As a result of the changes, the Company recognized
$2.2 million ($1.5 million after-tax) of non-recurring pension curtailment
and transition costs.  In addition, the Company initiated a management
reorganization plan to strengthen selected roles in the organization
resulting in $0.5 million ($0.3 million after-tax) of reorganization
charges during the second fiscal quarter of 2009.

The effective tax rate for the second fiscal quarter of 2010 increased to
34 percent compared with 31 percent for the second fiscal quarter of 2009.
The increase is due primarily to the non-recurrence of the favorable
resolution of uncertain tax positions during the 2009 quarter.  Net income
for the fiscal quarter ended March 31, 2010 was $7.8 million, an increase
of 44 percent compared with $5.4 million for the second fiscal quarter of
2009.  The resulting diluted earnings per share for the second fiscal
quarter of 2010 were $0.83 compared with $0.58 for the second fiscal
quarter of 2009.  Excluding the effect of acquisition costs, net income for
the second fiscal quarter of 2010 was $7.9 million, or $0.84 per diluted
share.  Excluding the effect of the pension curtailment and transition
costs and the reorganization charges, net income for the second fiscal
quarter of 2009 was $7.2 million, or $0.77 per diluted share.

For the six months ended March 31, 2010, revenues increased 25 percent to
$59.0 million compared to $47.4 million at this time last year.  The gross
profit margin was 63 percent versus 67 percent from last year's six-month
period ended March 31, 2009.  Selling, general and administrative expenses
for the first half of fiscal 2010 increased 23 percent to $16.2 million
compared with $13.2 million in fiscal 2009.  In conjunction with the
acquisition activity during fiscal 2010, the Company incurred $1.7 million
($1.2 million, after-tax) of acquisition and reorganization costs.
Year-to-date net income was $12.9 million, an increase of 12 percent from
$11.6 million in the prior year period.  Earnings per diluted share were
$1.38 compared with $1.24 for the same period last year.  Excluding the
effect of acquisition and reorganization costs, net income for the first
six months ended March 31, 2010 was $14.2 million, or $1.52 per diluted
share.  Excluding the effect of the pension curtailment and transition
costs and the reorganization charges, net income for the first six months
of fiscal 2009 was $13.4 million, or $ 1.43 per diluted share.

SOLID FINANCIAL POSITION

Landauer ended the second fiscal quarter of 2010 with total assets of
$139.9 million and negative working capital of $0.1 million, due to the
current liability classification of $16.8 million in outstanding
borrowings.  The debt is classified as current, based upon management's
projection to retire the debt from operating cash flow within the next
twelve months.  The debt was incurred to support the acquisitions completed
during the fiscal first quarter of 2010.  Cash provided by operating
activities was $9.7 million, a decline of $5.4 million from the first half
of fiscal 2009.  The decline is due primarily to the reduction in the
benefit from prepaid taxes, and other timing related changes in the
components of working capital.


FISCAL 2010 OUTLOOK

Landauer's business plan for fiscal 2010 includes projections currently for
aggregate revenue growth for the year to be in the range of 25 to 30
percent.  Fiscal 2010 acquisitions are expected to contribute 20 to 23
percent of the growth.  The business plan includes expense spending of $2.5
to $3.5 million to support the completion of the Company's systems
initiative.  The Company projects a net income increase in the range of 4
to 8 percent, excluding the impact of acquisition and reorganization costs
in fiscal 2010 and the fiscal 2009 after tax impact of pension curtailment
and transition costs and reorganization costs of $1.8 million.
