2008-2017年广东省职业性放射性疾病诊断情况分析

目的 了解广东省职业性放射性疾病的诊断情况，分析职业接触特点和职业接触关键控制点。方法 对2008-2017年广东省内申请职业性放射性疾病的35个病例进行分析。结果 诊断为职业性放射性疾病的有10例，其中职业性放射性肿瘤8例，诊断时年龄M（P0~P100）为62.5（42~76）岁，放射工龄M（P0~P100）为27.5（5~33）年，病因概率PC值在26.34%~97.98%之间，PC值95%可信限上限均大于50%，75%的病例为井下矿石与矿物处理工作者，职业中同时接触α、β、γ射线。急性放射性皮肤损伤2例，职业中接触X、β射线，2人均为意外受照，且无法估算出两人确切的受照剂量。结论 部分用人单位和放射工作人员的知识、技术水平、防护意识还有待进一步提高，建议加强辐射防护培训，尤其是上岗前培训。

Analysis on occupational radiation disease diagnosis in Guangdong Province in 2008-2017

Objective To investigate the situation of diagnosis of occupational radiation diseases in Guangdong Province, analyze the occupational contact characteristics and the key control points of occupational exposure.Methods Analysis of 35 cases of applied occupational radiation diseases in Guangdong Province in 2008-2017 years.Results 10 cases were diagnosed as occupational radiation diseases, among this 8 cases as occupational radiation tumors. At the time of diagnosis their average age M(P0~P100) was 62.5 (42~76) years old and the radiation seniority was M(P0~P100) for 27.5 (5~33) years.The probability of causation (PC) value is between 26.34%~97.98and 95% confidence limit of PC value is greater than 50. 75% of the cases are miners and mineral treatment workers under the mine, who were exposed to γ、α、β rays in occupations. 2 cases were diagnosed as acute radioactive skin injury and mainly expose to γ、β rays in occupations. Two per capita is accidental exposure and unable to estimate the exact dose.Conclusion The knowledge, technical level and protection consciousness of some employing units and radiation workers need to be further improved, and the radiation protection training, especially the pre-service training, should be strengthened.
