The fading characteristics of KCl:Eu2+(150 ppm) thermoluminescent crystals is determined. It is shown that the fading cannot be correctly measured without taking into account the phenomenon of self-irradiation of the crystals, due to natural radioactive nuclide40K which is presented in potassium halide dosimeters. The results obtained can be useful in those applications of KCl: Eu2+crystals dealing with long-time exposures, or low-dose levels of radiation.© 1995 American Institute of Physics.
