低中放固体废物近地表处置场周围辐射环境调查研究

Research on the Radiation Environment around Low and Intermediate Level Radioactive Solid Waste Disposal Site

对某低中放固体废物近地表处置场周围进行辐射环境监测,分析该处置场运行过程对环境辐射影响。对处置场周围陆地γ辐射/贯穿辐射水平、气溶胶、沉降灰、空气中~3H、土壤、底泥、地表水、地下水、饮用水、陆生生物和水生生物的放射性水平进行检测,结果表明,该低中放固体废物近地表处置场运行过程周围辐射环境无明显变化,所有样品的检测结果均符合相关国家标准,本处置场的运行未对环境造成放射性影响。

In this paper,the radioactive level around a low and intermediate level radioactive solid waste disposal site was monitored,and analyzed the influence of disposal site operation on environmental radiation.Terrestrial gamma radiation or penetrating radiation level,and the radioactivity levels of aerosol,settling ash,3 H,soil,sediment,surface water,groundwater,drinking water,terrestrial organisms and aquatic organisms were determined.The results showed that there is no obvious change in the radiation environment of the low and intermediate level radioactive solid waste disposal site,the test results for all samples meet the relevant national standards.Thus,the low and intermediate level radioactive solid waste s disposal site has no radiological impact on the environment.
