Seasonal variations in radon concentrations in groundwater of Dehradun and Haridwar districts, Uttarakhand

Abstract

This study has checked 222Rn concentrations in groundwater from 27 sites of Haridwar and Dehradun, Uttarakhand, using the Durridge RAD-7. Seasonal variability reveals that the activity of radon is at its peak during the monsoon. Among the samples, 96.29% exceeded the United States Environmental Protection Agency’s Maximum Contaminant Level for radon during monsoon. The results indicated significant correlations between the concentration of radon and some factors like electrical conductivity and pH. The objective is to compare seasonal radon levels in groundwater, identify significant variations, and assess potential health risks by evaluating them against established safety guidelines.
