Abstract

A study on radiation level and radionuclide distribution such as (²¹⁰po and ²¹⁰pb) were determined in rock samples collected from the lower hills of western ghats, kanyakumari district. The activities are counted using Zns(Ag) alpha counter. The activity of ²¹⁰Pb was estimated through ²¹⁰Po by allowing the ²¹⁰Po plated solution for a period of 12 months to build up ²¹⁰Po from ²¹⁰Pb. The concentration of 210Po in rock samples ranged from 8.2 ± 0.3 to 36.2 ± 1.4 Bq/Kg. Mean while, ²¹⁰Pb ranged between 10.3 ± 0.4 to 41.6 ± 1.8 Bq/Kg. The levels of ²¹⁰Po and ²¹⁰Pb in the study region was found less and would not pose any significant radiological impact on the environment.
