Abstract

Sensitivity and Precision of Determination of 210Pb in Groundwater

Highlights

In arid regions, groundwater is the major source of fresh water to the residential human communities
The study indicated that the water contains high levels (9.8-102.7 Bq L-1) of unsupported 222Rn and considerable levels of natural uranium; 226Ra and 228Ra were of negligible levels (
There is a potential for these radio nuclides to increase in the groundwater with time as the radon emanation continues from the rock structures

Summary

Introduction

Groundwater is the major source of fresh water to the residential human communities. The occurrence of natural radio nuclides in groundwater is due to the possibility of the leaching of the salts of their elements from the rock-bearing minerals [1]. Radon-222 decays to two relatively long-lived progenies (210Pb, 22.3 years and 210Po, 138 days). These 222Rn progenies may be present and enhanced in the groundwater of high radon content adding extra radiation dose to the users of these waters [3]. There is a potential for these radio nuclides to increase in the groundwater with time as the radon emanation continues from the rock structures. An extension to this study is required to explore the effect of the continuous radon emanation on the accumulation of 210Po and 210Po in the groundwater of the Wadi
