Abstract

 DYED POLYMER FILMS prepared by simple technique of casting aqueous solution of poly vinyl alcohol (PVA) or poly vinyl butral (PVB) containing Brilliant Green (BG) on horizontal glass plate were studied to be used for high dose dosimetry. Both films were bleached with different rates on exposure to gamma ray. Chloral hydrate was added to both polymeric films and the effect of its concentration as well as dye concentration on response was studied. Wavelength of analysis is 633 nm. The radiation chemical yield (G-values) was calculated in presence and absence of chloral hydrate. The films exhibit negligible humidity effect during irradiation. Pre- and post- irradiation stability was examined.
