In this study, the changes in the linear attenuation coefficient for beta radiation of irradiated ZrO2 thin film samples were determined using transmission method. The film samples irradiated by gamma radiation at 0.430Gy, 0.672Gy, 1.195Gy and 2.690Gy. The utilization of Co-60 radioisotope with the activity level of 0.018021 Ci was preferred to control the absorbed dose. The changes in the linear attenuation coefficient for beta radiation were investigated to evaluate the variations of the irradiated samples. The linear attenuation coefficients were determined by using two different Sr-90 radioisotopes. Hence the details in characteristic properties were assessed with respect to two different activity levels respectively, 2558 mu Ci and 0.0513 mu Ci. There were the changes in linear attenuation coefficient of the samples with the rise of the absorbed dose. (C) 2015 The Authors. Published by Elsevier Ltd.
