ENVIRONMENTAL TLD
Precision reliability to withstand the toughest
environmental stresses
Environmental dosimeters are well suited to monitor low-
level gamma radiation and withstand the most intense
environmental situations. This dosimeter is designed
for outdoor applications and may be used to measure
radiation for site characterization, at site boundaries for
regulatory compliance, and to monitor public exposure.
Issued reports provide easy comparison to ion chamber
results.
The Environmental TLD Dosimeter, encased in a holder
that protects against moisture, can be attached to fences,
gates, trees, or other objects in the environment for quick
access.
LEAK TEST
Reliable radiation source for leak testing
The Dosimetry Services Division provides complete Leak
Test kits for reliable testing of alpha, beta, or gamma
emitting radiation sources. Once completed, you will
receive a comprehensive report that lists each source
tested and the results in microcuries (μCi).
An instruction sheet provides step-by-step instructions.
