摘 要:为了查明江西省上饶县某石煤矿区的天然放射性水平,采集了石煤、煤矸石、土壤等固体环境介质及河水、水库水、井水、矿坑水等水体环境介质,并开展了调查区固体、水体环境介质的辐射环境质量评价。结果表明,区内石煤、煤矸石中238 U、226 Ra含量较高,严禁用作建筑材料。土壤中核素238 U、226 Ra含量均值为259.4Bq/kg、223.4Bq/kg,分别为江西省土壤背景值的4.5、4.2倍。矿区周边河水、水库水及井水放射性核素浓度低于生活饮用水指标值,不存在辐射安全隐患,而矿坑水则超过污水排放限值。石煤的开发利用造成了矿区周边局部地区放射性水平增高,应采取相应的防治措施。In order to ascertain the natural radioactivity level of a stone coal mine area in Shangrao County,Jiangxi Province,solid environmental media such as stone coal,coal gangue and soil,and water environment media such as river water,reservoir water,well water and mine water were collected and carried out.Radiation environmental quality assessment of solid and water environment media in the survey area.The results show that the content of 238 U and 226 Ra in stone coal and coal gangue is high,and it is strictly forbidden to be used as building materials.The average contents of nuclides 238 U and 226 Ra in soil were 259.4 Bq/kg and 223.4 Bq/kg,which were 4.5 and 4.2 times of the soil background value of Jiangxi Province,respectively.The radionuclide concentration of river water,reservoir water and well water around the mining area is lower than the drinking water index value,there is no radiation safety hazard,and the pit water exceeds the sewage discharge limit.The development and utilization of stone coal has caused the radioactive level in some areas around the mining area to increase,and corresponding prevention measures should be taken.
