Simulation of competing fading and irradiation effects in thermoluminescence (TL) dosimetry: First order kinetics

The aim of this paper is to give some useful expressions for fading correction in practical situations as they can be encountered in radiation protection dosimetry monitoring, i.e. personal, environmental and clinical dosimetry. They are obtained considering the first order Tl process and the general case in which, during the experimental period of time, two effects are in competition between them: one is the trapping rate due to a continuous irradiation over all the experimental period, i.e. environmental background irradiation; the second one is the detrapping rate which takes place at the same time, i.e. thermal fading.
