Abstract

A self-irradiation process has been observed in potassium halide thermoluminescent crystals. The 0.0117% abundance of the radioactive nuclide 40K in natural potassium, with a halflife of 1.28×10 9 years, is responsible for about 4.9 μGy/h of self-irradiation dose. The present finding is of importance in relation to the performance and limitations of recently proposed solid state dosimeters based on doped potassium halide crystals.
