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.

聚烯丙基碳酸二乙二醇酯(PADC)聚合物作为UVC剂量计:结合了热和UVC处理的新技术

这项研究的目的是研究在辐射剂量学应用中PADC聚合物薄膜的使用。借助于UV / Vis分光光度法表征了光学性质和光学常数。应用了两种组合处理方式:一系列的UV和热退火,反之亦然,以及仅涉及UV暴露的单独处理。最终结果证明高度依赖于联合治疗的顺序。通过将曝光剂量提高至4.458 kJ / cm 2,事实证明吸收边缘,折射率,衰减系数和光学电导率受到很大影响。在第二种组合模式下(UV退火后),但在其他模式下则没有显示这种行为。通过使用第二种模式,此PADC聚合物的剂量特性显示出极好的潜力,可以对0.446至4.458 kJ / cm 2范围内的紫外线暴露剂量进行唯一估计。
