Abstract:
Three dosimetric properties of poly allyl diglycol carbonate (PADC) and their response to gamma irradiation are put forth. The variation of the optical absorption edge with the received dose can be used as a dosemeter for doses >500 kGy. The variationdielectric function is, to some extent, linear with dose logarithm but has a low precision. The fluorescence emitted from the irradiated PADC upon illumination by the 346-nm UV radiation intensifies the changes in the dielectric properties and shows an excellent dosimetric behaviour in response to gamma ray in both precision and simplicity of procedure. Results showed that this property could be used as a dosimetric properties for measuring doses between 100 Gy and 6 MGy.
