目的:了解放射工作人员的健康状况,有效预防职业病危害,加强其健康管理,为进一步改善放射防护提供科学依据。方法:对温州市923名放射工作人员进行专项职业健康检查,实验室主要检测白细胞计数、外周血淋巴细胞染色体畸变率和微核率,采用SAS统计软件进行分析。结果:放射工作人员中,白细胞计数异常率为5.20%,女性7.77%。淋巴细胞染色体畸变异常率2.49%,职业为工业探伤10.00%显著高于放射诊疗2.30%。淋巴细胞染色体畸变率与年龄、职业、单位分类有关,年龄≥40岁高于<40岁,职业为工业探伤高于放射诊疗,省市级医疗机构高于民营医院和县级及以下医疗机构。淋巴细胞微核异常率1.19%。淋巴细胞微核率与单位分类、职业及其工龄、年龄有关,县级及以下医疗机构(工龄≥15年高于<15年)高于省市级医疗机构和民营医院,职业为工业探伤高于放射诊疗,随着年龄增大而增加。结论:温州市放射工作人员的健康状况已受到一定的辐射影响,应加强对年龄大、工龄长的放射工作人员的健康管理,改善工作条件,尤其要加强对工业探伤员的防护保障。
Objective: To understand the health status of radiation workers, effectively prevent occupational hazards and strengthen their health management, so as to provide a scientific basis for further improving radiation protection. Methods: A total of 923 radiologists in Wenzhou were enrolled in special occupational health examination. The laboratory mainly tested the white blood cell count, chromosome aberration rate and micronucleus rate of peripheral blood lymphocytes. The data were analyzed by SAS statistical software. Results: Radiation workers, white blood cell count abnormalities was 5.20%, 7.77% of women. Lymphocyte chromosomal aberration rate of 2.49%, occupation of 10.00% for industrial testing was significantly higher than radiation treatment 2.30%. Lymphocyte chromosome aberration rate and age, occupation, unit classification, age ≥40years old <40years old, occupation is higher than radiological diagnosis of industrial testing, provincial and municipal level medical institutions than private hospitals and county level and below medical institutions. Lymphocyte micronucleus abnormality rate of 1.19%. Lymphocyte micronucleus rate and unit classification, occupation and their length of service, age, county-level and below the medical institutions (15 years of service ≥ 15 years) higher than the provincial-level medical institutions and private hospitals, occupations for the industrial testing of high In radiotherapy, increased with age. Conclusion: The health status of radiation workers in Wenzhou City has been affected by certain radiation. Health management of radiation workers who are older and have a longer working life should be strengthened and the working conditions should be improved. In particular, the protection and protection of industrial radiographers should be strengthened.
