[目的]探索放射作业人员放射工龄与外周血象的关系,为放射人员防护工作重点提供理论依据。[方法]1404名放射作业人员为照射组,260名从事非放射医务人员为对照组,进行外周血细胞分析,将检查结果进行两组血象异常指标比较,不同放射工龄组的相关血细胞均值单因素方差分析、放射工龄与相关血细胞计数两变量的相关以及线性回归分析。[结果]照射组白细胞、血红蛋白、血小板异常发生率与对照组比较,差异有统计学意义,P﹤0.01。不同放射工龄组方差分析中血红蛋白、血小板、单核细胞均值F检验差异有统计学意义,分别为P﹤0.01、P﹤0.05、P﹤0.05。放射工龄与血小板相关分析中两者呈显著负相关,P﹤0.01,线性回归分析中存在极显著性,回归方程为:PLT=218.767-0.401N(N代表放射工龄数)。放射工龄与血红蛋白相关分析中呈显著正相关,P﹤0.01,线性回归分析中存在极显著性,回归方程为:HB=148.795+0.112N(N代表放射工龄数)。[结论]放射作业工龄作为职业暴露的一方面与放射人员血象变化具有一定的关系。
[Objective] To explore the relationship between radiation workers’ length of service and peripheral blood, and provide the theoretical basis for the radiation protection work. [Method] 1404 radiological workers were irradiated group and 260 non-radiological medical staff were used as control group. Peripheral blood cells were analyzed. The results of the examination were compared between two groups of abnormal blood group indexes. The correlation blood cell mean single factor variance Analysis, correlation of two variables of radiation age and related blood cell counts, and linear regression analysis. [Results] The incidence of leukocyte, hemoglobin and platelet abnormalities in irradiation group were significantly different from those in control group (P <0.01). There were significant differences in mean test of hemoglobin, platelet and monocyte in different radiation age group ANOVA (P <0.01, P <0.05, P <0.05). Radiation length of service and platelet-related analysis showed a significant negative correlation between the two, P <0.01, linear regression analysis was significant, the regression equation was: PLT = 218.767-0.401N (N represents the number of radioactive years of service). There was a significant positive correlation between radiation length of service and hemoglobin, P <0.01. There was a significant difference between the two groups in regression analysis. The regression equation was: HB = 148.795 + 0.112N (N represents the number of AIDs). [Conclusion] As a part of occupational exposure, radiation working length of service has a certain relationship with radiographic personnel blood changes.
