Abstract

 Gathering two pH indicator dyes m-cresol purple (MCP), tetrabromophenolphthalein ethyl ester (TBPE), previously studied as individual dosimeter each at low dose application in the same polymer matrix (PVA) extends the application dose response to 60 kGy. This flexible plastic film changes its colour from green to red passing through yellow colour on exposure to γ-rays photons due to the consequent lowering of pH caused by HCl generated from the radiolysis of chloral hydrate. Effect of different concentrations of chloral hydrate on response of the film was investigated. The film shows excellent stability before and after irradiation. The film has excellent stability in 10% to 50% relative humidity range (RH). The overall combined uncertainty (at 2ϭ) associated with measurement of response (Ai/ A0) at 438nm for dose range 5-60kGy is 6.33 %. So this film has the ability to monitor the absorbed dose in low and moderate irradiation dose due to its excellent stability before and after irradiation with a significance confidence level.
