Abstract

The activity concentrations of Naturally Occurring Radioactive Materials (NORM) in coal and coal combustion residues (CCRs) were determined employing low-level gamma-ray spectrometry. The activity concentrations of the NORM radionuclides present in coal and CCRs samples studied were found to be significantly higher than the world average values reported by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). The radiological hazard assessment based on the data obtained in the present work points out to long-term radiological implications for workers and the public living in an and around coal fired power plants.

用低水平本底伽马射线能谱法评价煤及其燃烧残留物中天然存在的放射性物质（NORM）

采用低水平伽玛射线能谱法测定了煤和煤燃烧残渣中天然存在的放射性物质（NORM）的活度浓度。所研究的煤和ccr样品中存在的标准放射性核素的活性浓度发现大大高于联合国原子辐射影响科学委员会（辐射科委会）报告的世界平均值。基于本工作所获得的数据进行的辐射危害评估指出了对居住在燃煤电厂及其周围的工作人员和公众的长期辐射影响。
