Abstract

 THESE FILMS contain a mixture of two dyes namely bromothymol blue (BTB) and methyl orange (MO) indicator with different concentrations of alanine in poly(vinyl alcohol) (PVA). The colour of this film changes from green to colourless by irradiation due to the consequent lowering of pH of the film caused by the H+ generated from radiolysis of α-alanine. The response of these films can be modified by changing the α-alanine concentration and the ratio of the two dyes. As a result, these films can be used as a dosimeter in high dose range. The dosimetric parameter e.g., dose response, effect of relative humidity, pre- and post-irradiation stability of these films are investigated.
