摘要
[目的]了解上海市9个区(即原市区范围)放射诊疗机构中放射工作人员健康状况,研究剂量与健康效应指标之间的相关性。[方法]利用调查表法对上海市9个区的放射诊疗机构中的2086名放射工作人员进行调查。[结果]上海市9个区放射诊疗机构放射工作人员2001～2005年平均累积剂量为0.72mSv。按工种划分,以介入放射工作人员最高,达到1.56mSv,牙科放射工作人员最低,为0.43mSv(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、中性粒细胞数、淋巴细胞数的异常率分别为33.33%(P<0.05)、40.91%(P>0.05)和45.45%(P>0.05),较其他工种略高。年平均累积剂量与白细胞数(r=0.061,P=0.017)和血小板数(r=0.098,P=0.000)之间存在正相关。[结论]上海市区放射诊疗工作人员在2001～2005年期间所受职业照射剂量较低,但工种间存在差异(P<0.05);介入放射工作人员部分血液学指标异常率较其他工种高;年平均累积剂量与部分血液学指标之间存在一定的相关性。
[ Objective ] To investigate the health status of diagnostic radiology and radiotherapy workers in Shanghai downtown areas and to find the correlation between personal dose and health indices. [ Methods ] Questionnaires were collected from 2086 radiation workers in 9 districts. [ Results ] The average year personal cumulative dose during 2001-2005 was 0.72 mSv, with a maximum of 1.56 mSv in interventional radiology workers and a minimum of 0.43 mSv in dental radiography workers （ P 〈 0.05 ）. The average year personal cumulative dose of workers between groups with different service length have no statistic significance （ P 〉 0.05 ）. The abnormal rates of hemoglobin （ Hb ）, neutrophilicgranulocyte （ NEUT ） and lymphocyte （ LYM ）from persons who were engaged in interventional radiology were 33.33% （P〈0.05）, 40.91% （P 〉 0.05 ）and 45.45% （ P 〉 0.05 ）, respectively slightly higher than other radiation workers. Positive correlation was found between the average year personal cumulative dose and white blood cell（ WBC ）（ r=-0.061, P=0.017）, as well as and platelet（PLT）（ r=-0.098, P=0.000）. [ Conclusion ] The personal dose which diagnostic radiology and radiotherapy workers in Shanghai downtown areas received is relatively low during 2001-2005, while difference exists between types of work （P〈0.05）. The abnormal rate of some blood parameters from persons who were engaged in interventional radiology is higher than others. Correlation is exists between personal cumulative dose and some blood indices.
