Polyallyl diglycol carbonate (PADC) polymer as a UVC dosimeter: A new technique combining thermal and UVC treatments

Abstract The aim of this study was to investigate the use of a PADC polymer film in dosimetric applications for UV radiation. Optical properties and optical constants have been characterized by means of UV/Vis spectrophotometry. Two modes of combined treatment were applied: a sequence of UV and thermal annealing and vice versa, as well as a separated treatment involving UV exposure only. The final results proved to be highly dependent on the order of the combined treatments. The absorption edges, refractive indices, attenuation coefficients, and optical conductivities proved to be highly affected by increasing the exposure dose up to 4.458 kJ/cm2 in the second combined mode (post-UV annealing), but in the case of the other modes did not show such behavior. The dosimetric properties of this PADC polymer show excellent potential for a unique estimation of UV exposure doses over the range 0.446 to 4.458 kJ/cm2 by using the second mode.
