Effect of different climatic conditions on the performance of CaSO 4: Dy. thermoluminescent dosimeters

Abstract

Performance of Teflon embedded thermoluminescent CaSO 4: Dy discs manufactured by the Division of Radiological Protection, Bhabha Atomic Research centre, Bombay has been studied under extreme climatic conditions prevailing in India to obtain the maximum effect of the variables; in actual practice the effect will be less than that revealed during experiments. Significant fading to the extent of 20% has been observed under ambient storage temperature range of 25°C to 34°C and 99% relative humidity after one month from the date of radiation exposure.
