Study of Gross Alpha and Gross Beta Activities in Rock Samples of Western Ghats in Kanyakumari District

Abstract

The present study was carried out to examine the gross alpha and gross beta activities in rock samples in Kanyakumari district. Twenty Four samples were collected from different locations in Western Ghats. The gross alpha and gross beta activities were measured by using zinc sulphide scintillation detector and low beta counter. In this present study the gross alpha activity was maximum at L22 (1397.85 Bq/Kg) and minimum at L7 ( 53.76 Bq/Kg ) with an average of 582.44Bq/Kg and the gross beta activity was maximum at L2 (3815.79 Bq/Kg) minimum at L7 (833.33 Bq/kg) with an average of 2081.51Bq/Kg.
