Abstract
A radio-chromic film dosimeters based on polystyrene binder and dithizone dye are invented for high dose applications. The dose response of Dz-PS film dosimeters increases linearly with increase absorbed dose up to 100 kGy. The dose sensitivity of the films increases strongly with increase of concentrations of dithizone dye. The effects of irradiation temperature, relative humidity, dose rate and the stability of the response of the films after irradiation were investigated and found that these films could be used as routine dosimeter in industrial radiation processing.
