Abstract

Abstract: Tank waters from 13 Community Groundwater Systems (CGS) showed average radon reduction rate of 26.5% (varying from −17.9% to 63.3%). When applying the reduction rate of 26.5% to the nationwide CGS, the percentage of CGS having radon level above 100 Bq/L decreases from 28.8% to 22.0%. The natural radon reduction method would be applied to the CGS having radon level slightly exceeding guideline of WHO, as an alternative for aeration or GAC. Highlights: We measured radon contents of groundwater and tank water from 13 villages in Korea. The natural reduction rates of radon range from -17.9% to 63.3% (average of 26.5%). When applying the average natural reduction rate of 26.5% to the nationwide CGS. Percentage of CGS having radon level above 100 Bq/L decreases from 28.8% to 22.0%.
