GLENWOOD, ILL.--NOVEMBER 9, 2009--LANDAUER, INC. (NYSE: LDR), a recognized
leader in personal and environmental radiation monitoring services, today
announced the completion of two acquisitions in accordance with its
long-term strategic priorities.

"We are pleased to announce the acquisitions of Global Physics Solutions,
Inc. (GPS) and Gammadata Matteknik AB (GDM)," said Bill Saxelby, President
and CEO of Landauer. "These acquisitions position Landauer to execute on
our long-term strategic priorities to drive competitive growth and pursue
strategic expansion.  These high quality companies complement Landauer's
competencies and the financial characteristics of our core business while
providing entrance into new market segments."


GLOBAL PHYSICS SOLUTIONS, INC. (GPS)

The acquisition of Global Physics Solutions, Inc. (GPS), completed on
November 9, 2009,  for $22 million in cash, initiates Landauer's strategic
expansion through the extension of services to ensure the safe utilization
of radiation in the healthcare setting.

Based in Texas with operations throughout the Midwest, GPS is the leading
nationwide provider of Medical Physics Services to hospitals and radiation
therapy centers.  Medical Physics Services is estimated to be a $1 billion
domestic market that includes clinical physics support, equipment
commissioning, accreditation support, imaging equipment testing and
educational services.  Medical physicists provide clinical and operational
support in the safe application of radiation for diagnosis and treatment of
patients.

Saxelby explained, "As we look to expand the scope of our core occupational
health monitoring business, the Medical Physics Services sector is
attractive to us because it is a service model that complements our core
business focus of radiation safety and exhibits attractive growth
characteristics. Global Physics Solutions is healthcare focused with the
same customers as Landauer, has regulatory support, and has a recurring
revenue model with high return characteristics. This large and expanding
market opportunity provides us with a substantial growth platform and the
current market is highly fragmented with no one company controlling more
than two percent of the market."

                                                      LANDAUER, INC.



"The GPS leadership team is excited to join Landauer," noted Len Wright,
President and CEO of GPS. "Landauer's leadership in radiation safety,
combined with our leadership in medical physics will provide a compelling
service offering to our shared customers."

Saxelby added, "We chose GPS not only because they are the largest company
in the market, but they are also recognized as thought leaders in the
industry and have been able to attract expert medical physicists and a blue
chip customer base. This move expands our leadership in the radiation
science and services arena and helps us better address the desire of the
medical community to understand the impact of increased utilization of
radiation in medical procedures on patient safety."

Landauer acquired GPS from DW Healthcare Partners, a leading private equity
firm focused exclusively on the healthcare industry. Robert W. Baird & Co
acted as financial advisors to Landauer on this transaction.


GAMMADATA MATTEKNIK AB (GDM)

The acquisition of Gammadata Matteknik AB (GDM) completed on November 2,
2009, for $6.7 million in cash, aligns with the company's competitive
growth objective through expansion of the company's international platform
with the leading European provider of radon measurement services. Radon is
a naturally occurring radioactive gas that can lead to the increased risk
of lung cancer. The World Health Organization recently recommended that
countries lower radon levels to control the presence of radon in homes and
commercial settings.

GDM has operations outside of Stockholm Sweden and provides measurement
services primarily in the Scandinavian region and throughout Europe. This
transaction will leverage the Company's recent acquisition of the Studsvik
dosimetry service in Sweden, now called Landauer Persondosimetri AB.

"The stability of our core businesses and strong cash flow we generate is
enabling us to execute on our three strategic growth priorities as
planned," explained Jonathon Singer, Chief Financial Office of Landauer,
Inc. "We remain committed to approaching any strategic expansion
opportunities in a thoughtful and measured manner, and are confident that
we will be able to build upon our success in the coming years."
