浙西,皖南石煤及其建材制品中的放射性元素对人体的影响

在石煤资源丰富的浙西、皖南地区测试结果表明,部分石煤渣砖含有的铀等放射性辐射强度,已超过了非职业辐射工作人员的容许值。部分石煤渣砖和水泥中的当量镭比活度和有效镭浓度也超过了国家对非职业辐射工作人员的安全限量,因此应对石煤建材制品的生产和应用持慎重态度。铀等放射性元素在石煤层中仅是局部富集,含量高的石煤层限于个别地段。因而,对辐射强度大、放射性核素含量高的个别富集地段应放弃开采。同时,对生产工人要按国家有关辐射防护条例,采取有效防范和劳保措施。

The Influence on Human Health of Radioactive Elements in Stone Coal and lts Building Material Manufacture in the Areas of West Zhejiang and South Anhui Provinces

The stone coal and its building material manufacture in the areas of west Zhejiang and south Anhui provinces show that the radioactive intensity exceeds the permitted level for non-professional radioactive workers, and the equivalent activity of Ra and effective Ra concentration also exceeds the national safe limit. A prudent pclicy should be taken concerning the production and usage of such building material manufacture, though the stone coal strata which contains high radioactive nuelides is distributed only in individual place.
