Abstract

Abstract: Through sampling the surface water that was from one uranium mine in southern Hunan, the radioactive metals and heavy metals of 20 water samples were analyzed by the method of inductively coupled plasma mass spectrometry（ICP-MS）. The correlation among the heavy metals and the radioactive metals were researched by the SPSS. Moreover, the method of Nemero index was selected to evaluate the water quality. The results indicated that the content of the most heavy metal and the radioactive metals of Water-Ⅰ （steams near the mine） was higher than that of Water-Ⅱ（the main river）, and the content of Tl, Ni in Water-Ⅰ exceed standard. The content of the radioactive metals of U and the heavy metal elements Pb, Ni, Tl, Cu, Co and Zn, was significantly related at 0.05 level or 0.01 level, which indicated that the source of this metals was possibly same. The main pollution sources of uranium mining were the waste water from mining, crushing rocks and waste rock yards. The uranium mine as a whole was at an excellent level.

Key words: radioactive metal, heavy metal, uranium mine, surface water
