ABSTRACT
Abstract: This paper presents the precise method to estimate the dependence of linear and mass attenuation coefficients of gamma rays on concentration of Manganese (II) chloride (MnCl2). The experiment was done using GSpec gamma spectroscopy system. The GSpec consists 2"x 2" NaI (Tl) detector with Multichannel analyzer (MCA). The GSpec has built in 14 Pin PMT base.The GSPEC is pc based Gamma Ray Spectroscopy system, which communicates with PC through USB port. In this experimental work 137Cs radioactive source emitting 0.662 MeV gamma rays has been used for analyzing the dependence of linear and mass attenuation coefficients of gamma rays on concentration of MnCl2. The spectral analysis was made using Spectrum Analysis and Analyzing Software (SAAS). Inorder to minimize the effect of multiple scattering on the linear attenuation and mass attenuation coefficients, a good geometry experimental arrangement was setup. The experimental results shown that the linear attenuation coefficient varies linearly with concentration of MnCl2 solution. The experimental values of the linear attenuation and mass attenuation coefficients are in close agreement with the theoretical values.
