Abundances of Uranium and Radon in Groundwater of Taejeon Area

대전지역 지하수에 함유된 우라늄 및 라돈의 함량

The concentration of radioactive elements was measured from the groundwater samples of Taejeon Area. U and Rn concentrations of very high level were detected from many places, especially around Yusung. These levels are much higher than the concentration standards for the drinking water proposed by the United States Environmental Protection Agency. However, in Korea, there are no standard levels for the radioactive elements in drinking water yet. We think that it is necessary to provide such standards as soon as possible, and that the determination of radioactive elements in groundwater should be included in the routine analysis items for the drinking water quality, because many people currently use such relatively high level radioactive groundwater as their drinking water, especially around Yusung area.
