Description
Radiochromic films composed of polyvinyl alcohol (PVA) and phosphotungstic acid (PTA) were proposed and investigated. The influence of gamma radiation and accelerated electrons on the optical properties of the films was studied in the dose range of 1-150 kGy. Under the influence of radiation, absorption in the visible range with a maximum at 750 nm develops in the films and they turn blue. Absorption is proportional to the absorbed dose in the entire dose range studied. The upper limit of measurable doses using these films is three times higher than that of radiochromic films based on organic dyes. (authors)
