Comparative analysis of some radiosensitivity index results of certain radiation workers in Chongqing from 2018 to 2019

Objective This paper analyzes the physical examination results of blood routine, chromosome deformity rate, micronucleus rate and thyroid function test of some radiation workers in Chongqing from 2018 to 2019, understands the occupational problems of radiation workers, and provide scientific basis for putting forward reasonable suggestions method: Methods 2 656 cases in 2018 and 2 922 cases in 2019 were selected through the information platform of physical examination system. A total of 5 578 physical examination results in two years were statistically analyzed and analyzed. Results The abnormal rate of blood routine, the detection rate and abnormal rate of chromosome distortion and micronucleus, and the abnormal rate of thyroid gland function (T3, T4, TSH) between the control group and the radiation group are significant differences ( P < 0.05). There were significant differences in the abnormal rate of blood routine, thyroid function (T3, T4, TSH), chromosome teratosis rate, micronucleus detection rate and abnormal rate between radiation diagnosis and treatment and industrial flaw detection, but there was no significant difference in the abnormal rate of chromosome ( P > 0.05). There was significant difference between < 10 year group and 10~20 year group, and there was significant difference in platelet, white blood cell and hemoglobin between 10~20 year group and 20 year group ( P < 0.05). There was no statistical significance in erythrocyte difference ( P > 0.05). There was significant difference in the abnormal rate of thyroid function among the three working age segments ( P < 0.05). The detection rate of chromosome distortion was significantly different between < 10 years group and 10~20 year group ( P < 0.05), but there was no significant difference between the other two groups ( P > 0.05). There was significant difference in the abnormal rate between the two groups ( P < 0.05). There was no significant difference in pairwise comparison of micronucleus detection rate among groups ( P > 0.05), but there was significant difference in abnormal rate among groups ( P < 0.05). Conclusion The long-term low dose ionizing radiation environment will damage the hematopoietic and endocrine system of radiation sensitive human body. 摘要： 目的 分析 2018—2019 年重庆市部分放射工作人员血常规、染色体畸变率、微核率、甲状腺功能试验体检结 果, 了解放射工作人员的职业健康问题, 为提出合理的建议提供科学依据。 方法 通过体检系统导出 2018 年 2 656 份, 2019 年 2 922 份, 共计 5 578 份体检结果进行统计与分析。 结果 对照组、放射组 4 项血常规异常率、染色体畸变 和微核检出率和异常率、甲状腺功能 (T3、T4、TSH) 异常率差异具有统计学意义 ( P < 0.05); 放射诊疗和工业探伤四项 血常规异常率、甲状腺功能 (T3、T4、TSH) 异常率、染色体畸变检出率、微核检出率和异常率差异具有统计学意义 ( P < 0.05), 染色体异常率无统计学意义 ( P > 0.05); <10 年组和 10~20 年组差异有统计学意义, 10~20 年组和 ≥20 年组血小板、白细胞、血红蛋白差异有统计学意义 ( P < 0.05), 红细胞差异无统计学意义 ( P > 0.05); 甲状腺功能 3 个工龄段异常率差异有统计学意义 ( P < 0.05), 染色体畸变检出率两两比较 <10 与另两组有统计学意义 ( P < 0.05), 10~20 与 ≥20 差异无统计学意义 ( P > 0.05), 异常率两两比较差异有统计学意义 ( P < 0.05); 微核检出率两两比较差 异无统计学意义 ( P > 0.05), 异常率差异有统计学意义 ( P < 0.05)。 结论 长期低剂量电离辐射环境会对射线敏感的人 体造血系统、内分泌系统造成一定损伤。
