伴生放射性矿辐射环境影响评价中钍系关键核素的确定

Identification of the Key Nuclides of the Thorium Series in Radiation Environmental Impact Assessment of Associated Radioactive Mines

针对当前伴生放射性矿辐射环境影响评价中存在的问题,调研收集了UNSCEAR、IAEA、欧盟、美国、加拿大等机构和国家的研究资料,给出了不同研究所选取钍系核素的种类,并以核素的半衰期和放射性毒性为主要依据,初步确定了钍系关键核素。

Aimed at the current problem of radiation environmental impact assessment of associated radioactive mines,investigation and survey of the literatures from international organization and countries such as UNSCEAR,IAEA,EU,America and Canada were carried out;and the species of nuclides of thorium series in different studies were provided.Based on the half-life period and radiological toxicity of nuclides,the key nuclides of thorium series were preliminarily identified.
