江门市放射工作人员辐射剂量与健康效应相关性研究

Analysis of Correlation between Radiation Dose and Health Effect of the Radiation Workers in Jiangmen

目的探讨电离辐射剂量对放射工作人员健康的影响。方法以2015~2016年江门市从事普通放射、介入治疗、核医学、放射治疗等的放射工作人员为研究对象,对其外照射个人剂量监进行并结合实验检查进行分析,同时选取93名健康医务人员作为对照组。结果 2014-2015年平均87.4%的放射工作人员年有效剂量小于1 m Sv,从事介入治疗的放射工作人员人均年有效剂量均高于其他人员;不同工龄放射工作人员血象异常检出率不相同;介入治疗组的白细胞异常检出率、普通放射组的血小板异常检出率、核医学组和放射治疗组的中性粒细胞绝对值异常检出率与对照组比较,差异均有统计学意义(P<0.05)。结论电离辐射对放射工作人员的血象异常率有显著的相关性。

Objective To investigate the effects of ionizing radiation dose on the health of radiation workers. Methods Ra- diation workers in general radiology, interventional radiology, nuclear medicine, radiation therapy are regarded as the research objects. From 2015 to 2016 their external exposure individual dose had been monitored, inspected combining with experiment 93 healthy medical staff were selected as the control group. Results The average effective dose of 87.4% radiation workers was less than lmSv from 2014 -2015. Radiation workers engaged in interventional therapy was higher than that of others. The detection rate of blood abnormalities was different for radiation workers. The detection rate of leukocyte abnormality in the in- tervention group, the detection rate of platelet abnormality in the normal radiation group, the abnormal detection rate of the ab- solute value of neutrophils in the nuclear medicine group and the radiation therapy group were statistically significant （ P 〈 0.05 ）. Conclusion Ionizing radiation has a significant correlation to the abnormalities of bloodstains in radiation workers.
