铀矿勘探废弃物的环境放射性评价与治理建议

Environmental evaluation on radioactive wastes from uranium exploration and suggestion for reclamation

采用数字γ辐射仪和智能化X-γ辐射仪对川西北某地区进行过铀矿勘探活动的铀矿产地和藏族聚居地做了生态环境放射性评价,对该地的遗留设施与废弃物进行了监测。结果表明,经过数十年在该区进行的铀矿勘探活动,使局部环境遭到破坏,部分点上放射性污染较为严重,针对本地区气候特殊,以及生态环境等因素的局限性,提出了具体的生态环境恢复、放射性污染治理和环境保护的建议。

By using digital y radiometer and intelligent X-T radiometer, the radioactive evaluation on the ecological environment has been conducted in the northwestern Sichuan Province where uranium exploration has been carried out and where the Tibetan live in compact community. The abandoned facilities, wastes have been inspected and monitored. The results indicate that partial environment of the areas has been destructed by the uranium exploration for decades, and some areas have been seriously polluted by the radioactivity. Therefore, the proposals for restoring the ecological environment, controlling the radioactive pollution and protecting the environment have been tabled in concerning with the special climate and ecological environment.
