| 目的 为了提高放射卫生技术机构生物剂量估算能力和水平,促进放射工作人员职业健康检查机构的染色体畸变分析能力提升。方法 组织全国范围内的疾控中心、职防院(所)、大专院校、科研院所、核工业系统、医疗及体检机构等共144家机构开展2022年全国生物剂量估算能力比对工作。参加比对机构分为A类和B类两类比对,通过对染色体畸变的识别,来估算照射剂量(A类)或染色体畸变率(B类),组织机构对比对结果进行统计分析和汇总,并对不合格的原因和存在的主要问题进行分析和探讨。结果 参加本次生物剂量估算比对A类的机构有60家,其中合格的52家(优秀12家),不合格的8家,合格率为86.7%(其中优秀比例为20.0%),不合格率为13.3%。参加本次生物剂量估算比对B类的机构有84家,合格的机构有48家,不合格的机构有36家,合格率为57.1%,不合格率为42.9%。结论 大部分参加A类比对的机构具备生物剂量估算的能力,参加B类比对的机构,一半以上具有分析染色体畸变的能力,参加A类比对的机构总体能力高于参加B类的机构;通过该项工作,提高了全国相关机构在生物剂量估算和染色体畸变分析方面的能力。 |

| Objective To improve the ability of radiation health technical institutions for biological dose estimation. Methods A total of 144 institutions nationwide, including the CDC, prevention and treatment center for occupational disease, colleges and universities, scientific research institutes, nuclear industry systems, and medical and physical examination institutions, were organized to carry out the intercomparison of national biological dose estimation capabilities in 2022. The institutions participating in the comparison were divided into two types of A and B, through the identification of chromosome aberrations, to estimate the irradiation dose (A) or chromosome aberration rate (B). The results were summarized and compared, and the main problems were analyzed and discussed. Results There were 60 institutions in type A, 52 qualified institutions (including 12 excellent institutions) and 8 unqualified institutions, with a pass rate of 86.7% (20.0% excellent) and a failure rate of 13.3%. There were 84 institutions participating in the biological dose estimation comparison of type B, with 48 qualified institutions, and 36 unqualified institutions, the qualified rate was 57.1%, and the unqualified rate was 42.9%. Conclusions Most of the institutions participating in type A comparison have the ability to estimate biological dose, and more than half of the institutions participating in type B comparison have the ability to analyze chromosome aberration. The overall ability of institutions participating in type A comparison is higher than in type B. |
