Fading Studies of Natural Salt for Dosimetry Applications

Fading at room temperature is one of the most important properties of TL material. The purpose of the present studies is to find out the suitability of natural salt extracted from rivers of Mizoram for dosimetry applications. TL analysis of the gamma irradiated samples stored at room temperature was done within 2 hours, after 48 hours and 96 hours of irradiation. Experimental glow curves were fitted by using Kitis et al general order expression and the fitting parameters were obtained by authors using GCD method. TL analysis of samples showed good dosimetry peaks at about 205 C. Our studies indicate that the natural salt may be considered for dosimetry applications within 48 hours after gamma irradiation.
