摘要
测定了贵州省几个典型燃煤企业粉煤灰的天然放射性水平,分析了各粉煤灰样本的内、外照射水平及最大可掺入量。结果表明,贵州西部、北部和东部的粉煤灰放射性水平符合利用要求,应用范围广;中部的粉煤灰一般只宜用作建筑材料的掺入物或建筑物的外饰物。
The natural radioactivity level of fly ash which comes from several coal-fired enterprises in Guizhou Province was determined. And it was also analyzed that the internal and external exposure levels and maximum incorporation volume of the fly ash samples.
