Possible using of acid sensitive dyes embedded in poly(vinyl alcohol) in determination the irradiation doses

Abstract

Study a new film prepared via casting a mixture of aqueous solutions consists of Orange IV and Indigo Carmine dyes embedded poly (vinyl alcohol) for dose monitoring. The prepared film may be beneficial in low and moderate dose monitor range from 0 to 60 kGy. The film undergoes an obvious color change from green to red color on exposure to gamma photons nominated it to be used as label dosimeter. The range of response curve in the target film depends on the concentration of the added chloral hydrate. The film shows good stability pre and after irradiation. There is no effect of humidity in the range of (10-70 % RH). The overall combined uncertainty measured is 6.32%.
