“…On the other hand, they carry significant health concerns as well, including the chances of radionuclide and heavy metal contamination. In high radioactive background areas such as those near or within rare earth element (REE) mines, uranium mines or magmatic massifs, the radionuclide activity in groundwater depends on the ability of leaching and dissolving of minerals from aquifer rocks [1,2]. Tectonic activity, groundwater flow, weathering, natural weather and human/animal activities may lead to the release of significant amounts of radioisotopes into the surrounding environment, especially aquatic environments such as groundwater or spring water.…”

Abstract222Rn is among the most important issues for radiation exposure in/near high background radiation areas such as near rare-earth-element (REE) and uranium mines in North Vietnam. Seasonal 222Rn activity concentration in spring water was determined by RAD-7, with average ranges of 1270 ± 60–66,400 ± 2630 Bq m−3, therein the highest value was a REE, and the lowest a uranium mine. The 222Rn activity concentration was higher in the dry season, which could be attributed to 222Rn leaching to spring waters from nearby mines, and lower in the rainy season due to dilution by rain water. The 222Rn annual effective doses were within permissible limits.
