An analysis on geographical ascendancy and the effects of physico-chemical parameters on radionuclides concentration in the central and northern coastal regions of Kerala, India

Abstract

The present study investigates the correlation between physico-chemical parameters and natural radionuclides, and relates its distribution with geographical factors of the study area. For the same, the activity concentration of natural radionuclides such as 40K, 226Ra, and 232Th in sand samples collected from the central and northern parts of coastal Kerala, India has been measured using high efficiency NaI (Tl) detector and compared the concentration with ‘favoring factors for distribution’ that is lithology and drainage pattern. The activity concentration was also correlated with multiple phyisco-chemical parameters of the sand samples. The details of which are discussed in the manuscript.
