Thermoluminescent Dosimeters (TLD)

Dade Moeller offers Mirion TLDs which are based on state-of-the-art technology. These small, lightweight dosimeters come preloaded and are easy to wear. TLDs offer the advantage of precise response and long wear periods due to their resistance to environmental factors such as moisture and humidity.

All processing is fully automated, reducing the chance of human error and misidentification. Proprietary algorithms provide for exceptionally accurate dosimetry. Reports are computer generated with exposure histories automatically updated. Dosimeters come pre-loaded, eliminating the need for tedious badge loading.

TLDs respond accurately to beta, gamma, X-ray and neutron radiations. The response of each element is corrected by the application of its own unique element correction factor. Both TLDs allow for the reporting of deep, lens of eye and shallow doses.

Application

Any occupational worker with potential exposure to gamma, X-ray, beta and/or neutron radiation.
Nuclear medicine facilities, imaging centers, research diagnostic centers and all employees with potential exposure to gamma, X-ray and beta.

Nuclear power plant workers, research laboratories, hospitals, universities and industrial applications.
