介入放射工作人员健康状况调查分析

目的 了解介入放射工作人员健康状况，为开展辐射防护监测和风险评估提供依据。方法 收集介入放射工作人员职业健康检查资料并建立数据库，通过SPSS 18.0软件进行统计分析。结果 介入组眼晶体混浊、淋巴细胞微核率和染色体畸变率的异常率为24.0%、3.4%、3.7%，高于对照组的15.1%、1.1%、1.5%；介入组白细胞数（5.82×10⁹/L）低于对照组（6.03×10⁹/L）（P < 0.05）；随放射工龄增加，介入放射工作人员眼晶体、心电图、腹部B超、染色体畸变率等指标的异常率呈上升趋势，白细胞数和血小板数呈减少趋势（P < 0.05）。结论 长期低剂量电离辐射对介入放射工作人员产生一定的辐射损伤，放射工龄较长者尤为显著，应加强放射防护的监测和风险评估。

Investigation and analysis of health status of interventional radiology workers

Objective To investigate the health status of interventional radiology workers and provide the basis for health monitoring.Methods Occupational health examination data of interventional radiology workers were collected and a database was established. Statistical analysis was conducted by SPSS 18.0 software.Results The abnormal rates of eye crystal, lymphocyte micronucleus cell rate and chromosome aberration rate in the intervention group were 24.0%, 3.4% and 3.7% respectively, which higher than those in the control group (15.1%, 1.1% and 1.5%). WBC count (5.82×10⁹/L) in the intervention group was lower than that in the control group (6.03×10⁹/L) (P < 0.05). With the increase of radiological service life, the abnormal rate of eye crystal, electrocardiogram, abdominal b-ultrasound, chromosome aberration rate and other indicators of interventional radiology workers showed an increasing trend, while the white blood cell count and platelet count showed a decreasing trend.Conclusion Long-term low dose ionizing radiation has caused certain radiation damage to interventional radiological workers, especially for the elderly, so radiation protection and health monitoring should be strengthened.
