Alkali hallde thermoluminescent dosimeters

Abstract Single crystals of KCl: Ca have been studied as thermoluminescent dosimeters for the measurement of X-radiations from Cu and Mo targets in the range of 5 mR to 50000 R. Depending upon the amount of radiations received by these crystals, thermoluminescence peaks at 85°, 35° and 190°C are observed for a heating rate of 40°C/min. The total area under the thermoluminescence curve is observed to be directly proportional to the amount of radiations received by these crystals. The effect of the lag of time between the exposure to radiations and the heating for thermoluminescence has also been studied.
