目的了解清远市长期接触小剂量电离辐射对放射工作人员健康的影响,为保障放射工作者的健康和改进防护措施提供依据.方法按卫生部<放射工作人员职业健康管理办法>规定的体检要求,对清远市220名放射工作人员进行了职业健康检查并对结果进行分析.同时调查306名非放射工作的其他医务人员作为对照组分析.结果随着工龄增加,放射工作人员眼晶状体混浊率和眼科检查异常率增加,部分组间指标差异有统计学意义(P＜0.01);外周血象均在正常范围内,各组间指标差异无统计学意义(P＞0.05);微核率均在正常范围内,男性组中,放射工龄＜5年工龄与5～15年和＞15年工龄组的微核率比较,差异有极显著性(P＜0.01);与对照组比较,相同工龄的放射人员微核率差异无显著性(P＞0.05);血中尿酸、三碘甲腺原氨酸(T3)、四碘甲腺原氨酸(T4)、促甲状腺激素(TSH)值均在正常范围内,其中男性组＜5年工龄与＞15年工龄组的TSH值比较,差异有极显著性(P＜0.01).结论放射工作人员长期接触低剂量照射,仍有可能造成健康损害,应加强放射防护管理.

Objestive To explore the health effect of long term low dose radiation exposure.Methods Through occupational epidemiological examination, a cross-section investigation was carried out on 220 radiation exposure workers in QingYuan. Results Even the dose was under the threshold limit 20mSv/a, the abnormal rate of both ophthalmologic examination and crystalline lens blurred significantly increased with the increasing of exposure age. The values of peripheral blood cell count were in normal range,and there had no statistic difference in each two groups both in man and wowen. Compared to the male exposure age both 5 ～ 15 years and ＞ 15 years groups, the abnormal rate of peripheral lymphacyte micronucleus had significantly statistic difference in male exposure age ＜5 years group. The values of concentration of T3,T4and TSH were in normal level, and compared to the male exposure age ＞ 15 years group, the values of concentration of TSH had significantly statistic difference in male exposure age ＜5 years group. Conclusions With the increasing of the age in low dose radiation exposure, the hazard is probably increasing. Great attention should be paid to long exposure age workers and enhance the management of radiation exposure.
