What type of dosimetry tool is a film badge?

A film badge is considered a dosimetry tool that is sensitive to low levels of radiation. This type of device utilizes photographic film that changes in response to radiation exposure, allowing for the measurement of accumulated dose over a period of time. The film's response is proportional to the amount of radiation it is exposed to, making it particularly effective for monitoring exposure to low levels of radiation that might not be detected by other types of dosimeters.

Due to its sensitivity, film badges are valuable in environments where individuals may be exposed to radiation, such as in medical facilities or research laboratories, ensuring that safety protocols are followed by effectively tracking exposure levels. This characteristic distinguishes film badges from other types of dosimetry devices, which may not be as adept at detecting low doses or may serve different functions, such as real-time monitoring or providing alerts.
