title: Monitoring (7)Be and tritium in rainwater in Daejeon, Korea and its significance.
abstract: We investigated the concentrations of beryllium-7 and tritium in rainwater along with sodium concentration in the region of Daejeon, Korea for 7 months. The results demonstrate that (7)Be in rainwater is inversely proportional to the amount of sodium present and proportional to the rainfall. Also, it was observed that tritium reaches ground level about a month later than (7)Be. This study will guide prospective geological research applications associated with cosmogenic nuclides especially in rainwater for the Korean region.
