What is Film Badge?

A film badge is a personal radiation monitoring device worn by workers who may be exposed to ionizing radiation. It contains photographic film that darkens when exposed to radiation; the degree of darkening indicates the absorbed dose. Film badges provide a permanent, legal record of radiation exposure and can detect alpha, beta, gamma, and X-ray radiation.

Properties & Characteristics

Contains photographic film sealed in light-tight plastic holder. Multiple filters (aluminum, copper, tin, lead) for radiation type discrimination. Energy range: typically 15 keV–6 MeV. Minimum detectable dose: ~0.1 mSv. Worn for defined period (weekly, monthly) then developed and analyzed.

Uses & Applications

Personnel dosimetry in nuclear power plants. Radiation monitoring in hospitals (radiology, nuclear medicine). Industrial radiography. Research laboratories with radioactive materials. Legal dose record for radiation workers. Occupational health and safety compliance.

Safety Information

Worn by workers to monitor and limit radiation exposure. Proper wearing position (collar, torso) essential for accurate readings. Must not be left in radiation fields or exposed to heat/light. Regular replacement and processing required. Dosimetry records must be maintained by employer.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
