: These are generally the most affordable option for large-scale personnel monitoring compared to electronic dosimeters. Where to Buy Film Badge Dosimeters
: Built-in metal filters (like lead or aluminum) allow the lab to distinguish between different types and energies of radiation, such as beta vs. gamma.
A film badge dosimeter consists of a piece of radiation-sensitive photographic film inside a light-tight holder. When exposed to ionizing radiation like X-rays or gamma rays, the silver bromide crystals in the film darken. The degree of darkening is proportional to the radiation dose received, providing a permanent, legal record of exposure. Key Benefits of Film Dosimeters
