Individuals who work with or near sources of ionizing radiation, such as radiographers, nuclear power plant workers, dentists using X-rays, veterinary surgeons, and some research scientists.
The monitoring period is typically monthly or quarterly, depending on regulatory requirements and the expected level of exposure risk. The badge is sent to a laboratory for development and analysis.
No. A film badge does not shield or protect the wearer from radiation. It is purely a monitoring device that measures the dose received, enabling safety officers to ensure exposure remains within legal limits.
