Abstract: The paper reports some general properties of the radiochromic pararosanilinecyanide (PR-CN) dye polyvinyl butyral (PVB)-based film for the measurementof absorbed dose of electron beams. The optical absorption spectrum, the changesin optical densities as a function of film thickness, the distribution of backgroundoptical densities, reproducibility, stability, the time of establishing complete.response and effects of environmental factors on the background optical densityas well as the responses after irradiations have been experimentally investigated.
