A small pack of sensitive photographic film worn as a badge. A film badge indicates how much radiation the person wearing the badge has been exposed to over time. Technicians and radiologists wear film badges to make sure they are not overexposed to radiation.
A badge containing film that is sensitive to x-rays. It is used to determine the cumulative exposure to x-rays of persons who work in radiology.
A radiation exposure measurement tool known as a badge is worn by individuals, which contains an unexposed x-ray film. The badge is designed with various metals to capture and record variations in radiation levels. Periodically, the films within the badge are removed and developed, and the resulting density of the emulsion is measured to assess the level of exposure to radiation.
This is an instrument used by hospital personnel to keep track of their exposure to radiation. Film badges, typically worn by workers in X-ray and radiotherapy departments, are essentially pieces of photographic film housed in a holder, attached to their attire. The film comes with a sensitive (fast) emulsion on one side and a less sensitive (slow) emulsion on the opposite side. Minimal radiation exposure will only darken the fast emulsion; however, with higher levels of exposure, the slow emulsion starts to darken, and the fast emulsion becomes opaque.
