水泥企业210Po的排放水平

    210Po Emission Level in a Cement Plant

    • 摘要: 采用银片自镀制源,α谱仪分析测量,对某水泥企业工艺流程中所用原料、添加剂及水泥产品中210Po比活度进行了测量分析,并根据物料平衡分析了水泥厂210Po的最大排放量。结果表明:原料、添加剂中210Po的比活度为5.42~901.59Bq/kg;水泥产品中210Po的比活度为22.71~124.74 Bq/kg;据物料平衡关系计算得到该水泥厂210Po的最大排放量为7.55×1010 Bq/a,归一化的排放量为5.67×1010 Bq/Mt。

       

      Abstract: 210Po spontaneous deposited on silver foil. Using α spectrometer measured the specific activity of 210Po in raw materials, additives, and cement production during the production technology process of the cement plant. The specific activity of 210Po in raw material and additives varies from 5.42 to 901.59 Bq/kg. The specific activity of 210Po in cement production is range from 22.71 to 124.74 Bq/kg. According to the input output balance, the maximum emission is 7.55×1010 Bq/a; the normalized emission is 5.67×1010 Bq/Mt.
