GLENWOOD, ILLINOIS, APRIL 22, 2004 ... LANDAUER, INC. (NYSE symbol LDR)
reported today that net income for its second fiscal quarter ended
March 31, 2004 was $4,839,000, or $0.54 per diluted share, compared with
$3,030,000, or $0.34 per diluted share, in the same quarter in fiscal 2003.

Revenues for the quarter just ended were $18,262,000, or 8.4% higher than
revenues of $16,846,000 in the same period a year ago.  Higher domestic
revenues provided the majority of growth for the quarter, where improved
pricing, expanded ancillary and report revenues and modest unit gains were
realized.  Revenue growth also benefited from a continued weak U.S. dollar,
as well as increased business activity in Europe, Asia and Brazil.

Aggregate costs and expenses for the quarter just ended were $1,459,000
lower than a year ago.  Impacting the year-to-year comparison is
recognition in the second quarter of 2003 of an impairment charge of
$2,750,000 related to Landauer's Aurion service, offset by lower incentive
compensation expense in the amount of $400,000, resulting in a net
reduction in prior year operating income of $2,350,000.  Other costs in the
current quarter increased at a slightly higher rate than revenues,
primarily for international costs and expenses, salaries and benefits, and
professional fees.  Resulting operating income for the second quarter of
fiscal 2004 was $7,667,000, an increase of $2,875,000 compared with the
same period in 2003.

RESULTS FOR SIX MONTHS ENDED MARCH 31, 2004
- -------------------------------------------

For the first half of fiscal 2004, Landauer reported net income of
$8,844,000, or $0.99 per diluted share, compared with $6,839,000, or $0.77
per diluted share, for the same period in fiscal 2003.  Revenues for the
first six months of the fiscal year were $35,040,000, or 8.7% higher than
$32,238,000 reported for the same period in fiscal 2003.  Domestic revenue
growth, representing almost two-thirds of the increase, resulted from
improved pricing and modestly higher volume for measurement and reporting
services.  Higher international revenues resulted from a weak U.S. dollar
and some pricing and unit gains in most foreign markets.

Aggregate costs and expenses for the first half of fiscal 2004 were
$366,000 lower than a year ago.  As above, the comparison with a year ago
is impacted by recognition in 2003 of an impairment charge of $2,750,000,
offset by lower year-to-date incentive compensation expense of $350,000,
for a net reduction in 2003 operating income of $2,400,000.  Other costs
during the first half 2004 increased by approximately 10%, particularly for
salaries and benefits, international costs and expenses and professional
fees.  Resulting operating income thus far in fiscal 2004 was $14,026,000,
an increase of $3,168,000 compared with the same period in 2003.

LANDAUER, INC.                                                ADD 1



Year-to-date other income was $130,000 higher than a year ago with most of
the increase resulting from higher earnings of Nagase-Landauer, Ltd., the
Company's joint venture in Japan.  Income taxes for the first half of
fiscal 2004 were higher than a year ago as a result of higher income.  The
effective tax rate for the current year at 37.6% was slightly higher
compared to the first six months of fiscal 2003.


OUTLOOK FOR BALANCE OF FISCAL 2004

Landauer's business plan and outlook anticipates that revenue growth for
the year is expected to be in the range of 6-8%, evenly distributed among
the Company's traditional revenue sources.  Domestic revenue growth is
expected to occur as a result of pricing, moderate unit growth and
increased sales of ancillary services and products.  International revenue
growth is expected to benefit from a continued weak U.S. dollar, although
the impact of currency translation will likely diminish over the balance of
the year, as year-to-year exchange rate comparisons moderate.
Additionally, international revenue growth is expected to result from
higher pricing and increased units.

Aggregate costs and operating expenses for fiscal 2004 are expected to be
comparable to fiscal 2003 levels, reflecting the absence of a $2.8 million
non-cash impairment charge that occurred in 2003, offset by higher costs in
2004.  Any change in the value of the U.S. dollar relative to major foreign
currencies, however, may impact both revenues and costs for most non-U.S.
operations with only modest impact on operating income.  Net other income
in fiscal 2004 is anticipated to be comparable to a year ago and the
effective income tax rate for fiscal 2004 is expected to be 37.5%.
Resulting net income for 2004 is anticipated to be higher by 18 - 20%
compared with fiscal 2003.
