In particular, radon gas frequently exceeded the recommended groundwater (drinking water) guideline (4000 pCi L −1). High levels of radon gas were closely related with those of uranium because the former is a radioactive decay product of the latter. (2) The levels of the radionuclides in groundwater were highly related to the local geology. According to the ME's investigation results, radon levels in groundwater were higher in sequences of igneous rocks (especially granites
