负离子粉及产品的放射性监测及建议
|
摘要
目的调查研究负离子粉及产品的放射性水平。方法对某生产原料负离子粉及含负离子粉的黄土球、汽车座垫等产品进行放射性监测。结果研究发现负离子粉表面X-γ辐射剂量率高达3.0×10~(-5)Gy/h,~(238)U、~(232)Th、~(226)Ra等放射性核素活度浓度分别高达73.9 Bq/g、758 Bq/g、28.3 Bq/g。结论部分负离子粉及产品的生产、使用不满足有关标准的有关要求,值得相关部门的高度重视。
Objective To investigate the radioactive level of negative ion powder and products.Methods Radioactivity monitoring of negative ion powder, loess spheres containing negative ion powder, automobile seat cushion and other products was carried out.Result It is found that the γ dose rate above the negative ion powders reaches up to 3.0×10~(-5)Gy/h, and other radionuclide activity concentrationssuch as ~(238)U, ~(232)Th, ~(226)Ra are respectively as high as 73.9 Bq/g, 758 Bq/g and 28.3 Bq/g.Conclusion The production and use of some negative ion powders and products do not meet the relevant requirements of the relevant standards, which should be highly valued by relevant departments.
