In transporting autoclave bags to the kitchens, do not use the passenger elevators. Also, the bags should not be dragged across the floor or corridor. Anyone who works with radioactive materials or who works in the vicinity of a radiation area is issued a dosimeter. Film badges are an appropriate way to monitor external individual dose. A film badge consists of one or two pieces of photographic film enclosed in a light-tight wrapper and inserted into a plastic case or holder .
Film badges work the same way as medical and dental X-rays work.
The longer photographic film is exposed to radiation, the darker it becomes. Filters are built into the film badge holders to screen out different types and energies of radiation. Shallow dose is delivered by beta particles greater than 70 Kev and virtually all x and gamma rays. Deep Dose Equivalent includes dose delivered by any radiation capable of penetrating 10 mm of soft tissue. Lens of Eye Dose includes dose delivered by any radiation able to penetrate the protective tissues covering the lens of the eye.
