| 摘 要： | 通过对我国某废弃铀矿山地表贯穿辐射剂量率2、22Rn析出率、空气中氡及其子体浓度、土壤和水体中天然放射性核素含量的监测,调查和分析了矿山辐射环境现状.结果表明,该废弃铀矿山已受到放射性污染.其中,1#矿点和尾矿堆放射性水平较高,是矿区主要放射性污染源项,应采取整治措施.其他区域放射性较低,未超过国家基本限值.

| Abstract: | Through measurement of surface radiation dose rate,and exhalation rate of 222Rn,concentrations of radon and its daughters in the air and natural radionuclides contents in the soil and waterbody aimed at an abandoned uranium mine in our country,this paper investigated and analyzed the current situation of the radiation environment of the mine.The results showed that the abandoned uranium mine has been exposed to radioactive contamination.Among these mine,high-level radioactive 1# mine sites and tailing piles have been the main radioactive pollution sources of mining area and we should take remediation measures.Other regional radioactivity was lower and did not exceed the national limits. |
