莱芜市放射工作人员健康状况调查

Health Status of Radiation Workers in Laiwu City

  • 摘要: 目的

    了解莱芜市放射工作人员健康状况,探讨受照剂量与血液学指标的相关性。

    方法

    使用LiF(Mg,Cu,P)热释光个人剂量计定期监测,进行职业健康检查,使用SPSS软件进行处理分析,依据国家有关法律法规和技术标准进行评价。

    结果

    莱芜市340名放射工作人员2010-2014年平均累积剂量为0.74 mSv。按工种划分,以介入放射工作人员最高,达到1.58 mSv,牙科放射工作人员最低,为0.44 mSv(P < 0.05)。各工龄组间年平均累积剂量差异无统计学意义(P>0.05)。介入放射工作人员血红蛋白的异常率为37.50%,较其他工种高(P < 0.05)。年平均累积剂量与白细胞数(r=0.059,P=0.020)和血小板数(r=0.092,P=0.001)存在正相关关系。

    结论

    长期低剂量接触X射线对健康有一定影响。

     

    Abstract: Objective

    To evaluate the health status of radiation workers in Laiwu City and the correlation between personal radiation exposure dose and haematological indices.

    Methods

    Personal radiation doses of selected participants were measured regularly using LiF(Mg, Cu, P) thermo luminescence dosimeter and occupational health examinations were also performed. SPSS software was employed for statistical analysis. All personal dose data were appraised according to corresponding national codes and technical standards.

    Results

    The average annual personal cumulative dose(AAPCD) was 0.74 mSv for the 340 radiation workers in Laiwu City during 2010-2014. Categorized by job title, the interventional radiologists presented the highest AAPCD value of 1.58 mSv and the dental radiologists the lowest of 0.44 mSv(P < 0.05). No statistical differences in average annual cumulative dose were found across radiation workers grouped by service length(P>0.05). The abnormal rate of hemoglobin of the interventional radiologists was 37.50%, higher than the other radiation workers(P>0.05). Positive correlations were found of the AAPCD with white blood cell count(r=0.059, P=0.020) and platelet count(r=0.092, P=0.001).

    Conclusion

    Long-term low-dose X-ray exposure could affect the physical health conditions of medical workers exposed to radiation.
