Recently through existing national research, some areas exceed the value of proposed standards in the United States for radon(Rn-222) in groundwater and it becomes a problem. So the interest of radon in drinking water is increasing day by day. Accordingly, radon concentration in a groundwater including the natural mineral water was measured in this study. In the case of natural mineral water, representative drinking water to be distributed evenly throughout the country were selected and In the case of groundwater, groundwater of Gwang-ju and some areas of comparison were collected. So radon emissions through RTM1688-2(SARAD) were measured. In the case of natural mineral water, it shows that 41.32pCi / L ~ 740.24pCi / L were very low value compared to 4000pCi/L, so it seems to be no problem for drinking. In the case of groundwater, 35.35pCi / L ~ 3290.69pCi / L seems a significant difference. The size of the system or aquifer wells became large number of variables that affect the radon concentration. Groundwater in areas of comparison is 102.41pCi/L∼3333.97pCi/L and 3333.97pCi/L is the closest in in drinking baseline in 4000pCi / L . But this is also not a problem for drinking. Compared to a high concentration of the lipid water sources, containing radon can be seen that the situation will appear higher in the region of granite. Assuming that the worst case that we drink groundwater containing the highest concentration of radon, form of radon is like a saw blade distribution. Form of this condition repeat at the time of intake and is like a saw blade distribution. The results of this study are available to assess the risk of radon and to use the basis of provision for management standards and will be aim to expand awareness of the risk of radon safety about public health.
