Effect of Gamma Rays on The Bulk Etching Rate of LR-115 Detector

Abstract

It is important to measure the bulk-etching rate for any solid state nuclear track detectors, because they have an application in different fields of sciences. The effect of gamma rays emitted from 60 Co source with different doses on LR-115 detector was studied. The bulk etching rate of the detectors was measured before and after irradiation using gamma source. From the results the values of the bulk etching rate of LR-115 without gamma rays have been 3.10 μmh −1 and that under gamma irradiation with different doses were ranged from 4.60 to 8.77 μmh −1 . This means that the values of the bulk etch rate increase with increasing gamma doses.
