摘要：

Tritium and C-14 concentration in hot spring water in Korea were determined. Tritium in the most hot spring samples could not detected and concentration range was < 0.5-1.31 TU. And C-14 contents were ranged 1.7-78.6 pMC. From the H-3 and C-14 analysis, we found some hot springs are mixed with recent groundwater and hot spring water ages were estimated from 1,940 to 32,800 years. And also, Ra-226 and Ra-228 were determined simultaneously in hot spring water, and some other radionuclides were also analyzed. Content distribution of Rn-222 was 50-3,760 pCi/L, Ra-226 was < 0.003-0.15 Bq/L and Ra-228 was below the detection limit.
