Abstract

Dyed polymer films, prepared by a simple technique of casting aqueous solutions of poly(vinyl alcohol) PVA or poly(vinyl butyral) PVB containing quinaldine red (QR) on a horizontal glass plate, are useful as routine high-dose dosimeters. These flexible plastic film dosimeters are bleached when exposed to gamma rays. The response of these dosimeters depends on the concentration of QR and the polymer material. The radiation chemical yield (G-value) of both PVA and PVB dyed films was calculated and was found to increase with increasing dye concentration. The effect of relative humidity during irradiation as well as pre- and post-irradiation storage, on the response of the films is examined. These films are not affected by humidity change in the intermediate range of 10% - 50%.
