摘要
通过对黄石市3家集中式饮用水源地和2家矿冶公园共20个土壤样品中238U、232Th、226Ra天然放射性核素含量进行调查,并与1992年湖北省辐射环境调查数据进行比较,分析土壤天然放射性核素含量变化规律,为辐射管理提供科学依据。调查结果表明,黄石市土壤中238U、232Th、226Ra天然放射性核素含量与1992年黄石市本底值相比无显著变化,黄石市土壤天然放射性核素含量属于湖北省正常本底范围,并保持稳定。
The natural radionuclides content of 238U,232Th,226Ra in the soil of 20 samples were investigated,collected from the 3 centralized drinking water sources and 2 mining and metallurgical parks in Huangshi city,the environmental radiation level and changes were analyzed and were compared with the survey datas of radiation environment from Hubei province in 1992.The diversification pattern of radionuclides were analyzed,to provide the science basis for radiation management.Results show that the radionuclides content of 238U,232Th,and 226Ra present no significant changes in soils of Huangshi city,which are compared with the background value of Huangshi city in 1992.The natural radionuclides content in soils of Huangshi city is within the scope of local survey results in Hubei Province and remains steady.
