[目的]了解渝东片区从事放射工作人员的健康状况,为进一步改善放射卫生防护设施提供科学依据。[方法]对2007年渝东片区321名放射工作人员职业健康检查资料进行分析。[结果]神经衰弱综合症、眼晶状体混浊随工龄增加而升高;外周血象只有血小板随工龄的增加而稍上升;尿素氮异常率、淋巴细胞染色体畸变率和微核异常率都随工龄的增加而上升,其变化有统计学意义;心电图、B超、肌酐和肝功能异常与接触小剂量电离辐射无关。[结论]长期小剂量电离辐射对放射工作人员的健康有一定的影响,应加强放射防护工作。
[Objective] To understand the health status of radiological workers in the eastern part of Chongqing and provide a scientific basis for further improving the radiological protective facilities. [Method] The data of occupational health examination of 321 radiation workers in Chongqing area were analyzed. [Results] Neurasthenia syndrome and ocular lens opacity increased with the increase of seniority of service life. Peripheral blood only platelet slightly increased with the increase of service life; the abnormal rates of urea nitrogen, lymphocyte chromosome aberration rate and micronucleus anomalies increased with the increase of seniority While the changes were statistically significant. Electrocardiogram, B-ultrasound, creatinine and liver dysfunction were not related to exposure to low-dose ionizing radiation. [Conclusion] Long-term low-dose ionizing radiation has a certain impact on the health of radiation workers. Radiation protection should be strengthened.
