film badge


Definition A type of dosimeter that holds a film capable of absorbing radiation, which is used to monitor and quantify a radiation worker’s exposure to occupation-related x-rays and gamma-radiation. The badge may contain filters which shield parts of the film from certain types of radiation.

Note: The maximum radiation exposure allowed by NIOSH is 5000 mRad/year or 1500 mRad for any 3 months. While film badges are the most widely used radiation dosimeters on a global scale, they are little used in the USA, as multi-chip thermoluminescent dosimeters are preferred. 

Synonyms Film badge dosimeter, film dosimeter
