氧氯化锆(ZrOCl_2)生产流程中不同产物的天然放射性核素测定

Determination of Natural Radionuclides in process of producing ZrOCl_2

对某厂氧氯化锆(ZrOCl_2)生产流程中原料(铬英石,主要成份ZrO_2),三种废渣和成品氧氯化锆中天然放射性核素^(238)U、^(232)Th、^(226)Ra、^(40)K含量的测定结果表明,原料、几种废渣中都含有一定的放射性,各生产环节应采取适当的防护措施,或品氧氯化锆中基本不含放射性,可安全地应用于各生产和生活领域。

The content of natural radionuclides ^(238)U、^(232)Th、^(226)Ra、^(40)K in raw material (Zirconium silicate,main component ZrO_2),3 kinds of reject and product has been measured by HPGeenergy spectrum.Results show that some level of radiation exists in both raw material and rejects,protection measures should be taken in the whole process,product of Zirconyl Chloride has no radiation basically and can be used in production and life field savely.
