WebSep 20, 2024 · As a result, Wollan developed the film badge dosimeter — the first reliable device to track a worker’s cumulative exposure to ionizing radiation. Who was Ernest Wollan? In many ways, he was a pioneer — the first person to have the title “health physicist,” and the first to create a group fully devoted to radiation safety. The film holder usually contains a number of filters that attenuate radiation, such that radiation types and energies can be differentiated by their effect when the film is developed. To monitor gamma rays or x-rays , the filters are metal , usually lead, aluminum , and copper .
