TGP Offers Pro-GR Gamma Ray-Shielding Glass
Lead Glass Provides Increased Protection for Hospital and Medical Facility Workers
KIRKLAND, Wash. - Every day in the United States, doctors, nurses and technicians
work with radioactive substances designed to diagnose or treat illness. While patients
benefit from nuclear medicine and imaging technologies, frequent and prolonged
exposure to radiation can be harmful for medical personnel.
To help protect medical workers, Technical Glass Products (TGP) is pleased to offer Pro-GR lead glass, an ultra-high lead content glass suitable for shielding gamma rays.
Gamma rays are generated during medical imaging such as PET (Positron Emission
Tomography) and CT (Computed Tomography) scans, which doctors use to diagnose or
evaluate the effects of treatments on a range of maladies from cancer to brain disorders. www.tgpamerica.com
Pro-GR lead glass contains approximately 70 percent lead oxide, which is equivalent to
the ultra-high lead content block glass used in nuclear power facilities. The product's
manufacturer - Nippon Electric Glass Company, LTD - has evaluated Pro-GR's
shielding capability for both primary and scattered gamma rays. Their test results indicate
that a 14.2 mm-thick piece of Pro-GR lead glass provides gamma ray shielding
comparable to a 5 mm-thick sheet of lead.
In addition to shielding medical workers from gamma rays, Pro-GR lead glass provides
needed visibility of medical imaging operations. It transmits 83 percent of visible light,
offering excellent visibility.
Pro-GR lead glass is available in 14.2 mm or 21.3 mm thicknesses, depending on
shielding requirements. It is available in sizes up to 42 by 60 inches.
Under a special arrangement with Nippon Electric Glass Company, LTD, TGP is pleased
to offer Pro-GR lead glass in the United States west of the Mississippi River.
