GLENWOOD, ILLINOIS, APRIL 25, 2005 . . . LANDAUER, INC. (NYSE symbol LDR)
reported today that net income for its second fiscal quarter ended
March 31, 2005 was $5,143,000, or $0.57 per diluted share, compared with
$4,839,000, or $0.54 per diluted share, in the same quarter in fiscal 2004.

Revenues for the quarter just ended were $19,706,000, or almost 8% higher
than revenues of $18,262,000 in the same period last year.  Higher domestic
radiation monitoring activities represented approximately $700,000 of
revenue growth for the quarter, where higher pricing, increased ancillary
service revenues and modest unit gains were realized.  International
radiation monitoring revenue growth of almost $350,000 resulted from a mix
of increased business activity in Europe, Asia and Brazil and a weaker U.S.
dollar.  The balance of revenue growth was attributable to sales of InLight
products and services in the U.S. and abroad.

Aggregate costs and expenses for the quarter just ended were $1,207,000
higher than a year ago.  Higher international costs for the quarter were
attributable to InLight sales activity, a weak U.S. dollar and the closure
of an unneeded facility north of Paris.  Domestic cost and expense
increases resulted from higher professional fees and outside services
related to Section 404 work and market research, as well as higher
depreciation and amortization expense.  Resulting operating income for the
second quarter of fiscal 2005 was $7,904,000 compared with $7,667,000 for
the same period a year ago.


RESULTS FOR SIX MONTHS ENDED MARCH 31, 2005
- -------------------------------------------

For the first half of fiscal 2005, Landauer reported net income of
$9,573,000, or $1.06 per diluted share, compared with $8,844,000, or $0.99
per diluted share, for the same period in fiscal 2004.  Revenues for the
first six months of the fiscal year were $38,031,000, or 81/2% higher than
$35,040,000 reported for the same period in fiscal 2004.  Domestic revenue
growth, representing almost $1,325,000 of the increase, resulted from
improved pricing and modestly higher volume for radiation measurement and
ancillary services.  International radiation monitoring revenues were
approximately $750,000 higher, the result of higher pricing, increased
international business activity and a continued weak U.S. dollar.  The
balance of revenue growth for the first six months of 2005, or
approximately $900,000, was attributable to sales of InLight products and
services in the U.S. and abroad.

LANDAUER, INC.                                                ADD 1


Aggregate costs and expenses thus far in fiscal 2005 were $2,393,000 higher
than a year ago.  Higher international costs represented the largest
component and, as for the current quarter, reflects the costs for InLight
sales, currency translation and the planned costs associated with closing
the redundant facility in France.  Other categories of costs that were
higher include depreciation and amortization, professional and outside
service fees, direct materials and other production related costs.
Resulting operating income for the first six months of fiscal 2005 was
$14,624,000 compared with $14,026,000 for the same period in 2004.

Year-to-date net other income was moderately higher than a year ago where
earnings of Nagase-Landauer, Ltd., the Company's joint venture in Japan,
were higher by $165,000 and net interest expense was higher by $106,000.
Income taxes for the first half of fiscal 2005 were higher than a year ago
as a result of higher income.  The effective tax rate for the current year
of 37.1% compares with 37.6% for the first half of fiscal 2004.


OUTLOOK FOR BALANCE OF FISCAL 2005
- ----------------------------------

Management's review of the 2005 business plan indicates that no change in
the outlook is warranted and that aggregate revenue growth for the year is
anticipated to be in the range of 7 - 8%. The Company's traditional
domestic and international revenue sources are expected to grow at a rate
of 5.5 - 6.5% with sales for the InLight product line contributing to the
balance of revenue growth.  Sources of domestic revenue growth are expected
to include pricing, moderate unit growth and increased sales of ancillary
services.  Pricing and increased unit volume are expected to contribute to
international revenue growth in 2005, although currency exchange rates may
impact results reported in U.S. dollars.  Costs and operating expenses for
fiscal 2005 are expected to grow at a rate slightly higher than revenues.
Net other income in fiscal 2005 is anticipated to be comparable to the year
just ended and minority interest should further decline, as a result of the
elimination of minority interest in LCIE-Landauer.  The effective income
tax rate for fiscal 2005 is expected to be comparable to 2004 at 37.4%.
Based on the preceding estimates, resulting net income for 2005 is
currently anticipated to be higher by 6 - 8% compared with fiscal 2004.
