Abstract

Natural Barite was collected from Mangampeta mines of Cuddapah District, Andhra Pradesh, India, where it is one of the most common gangue minerals in the ore. The collected samples were subjected to ESR studies. The ESR spectrum of collected barite sample shows the existence of the hole type centre SO4- with the g-factor values 2.022 and 2.015 and the electron type centre SO3- with the g-factor values 2.0055, 2.0032 and 2.0021. In order to evaluate the barite as a ESR dosimeter material, it is very essential to study the power dependence, dose response and isothermal annealing. The obtained results reveal that the collected barite sample can be utilized as a ESR dosimeter for high doses measurement.
