目的 通过比较雷达站官兵和健康体检人员的外周血象指标,探讨磁场环境对外周血象的影响. 方法 试验组为某雷达站官兵189人,平均年龄(23.2士3.5)岁,从事雷达操作工作2年以上,生活工作区均在辐射范围内,无特殊防护措施.对照组为来空军总医院体检的官兵53人,平均年龄(21.3±2.6)岁,无电磁辐射暴露史.检测和比较两组人员的血常规,分析电磁辐射对外周血象的影响. 结果 ①试验组雷达兵外周血象不合格率为60.90％,其中试验组的血细胞比容、红细胞平均体积、红细胞平均血红蛋白含量、血小板平均体积、血小板分布宽度、淋巴细胞、淋巴细胞计数高于正常值,而中性粒细胞则低于正常值;试验组淋巴细胞、血细胞比容、血小板平均体积、中性粒细胞不合格率较高(39.68％、21.69％、17.46％、17.46％);对照组血细胞比容、淋巴细胞不合格率为3.77％、5.66％.②与对照组比较,试验组雷达兵血细胞比容、红细胞平均体积、红细胞平均血红蛋白含量、红细胞分布宽度、淋巴细胞、淋巴细胞计数、嗜酸性粒细胞、嗜酸性粒细胞计数、血小板压积、血小板平均体积、血小板分布宽度值均高于对照组(P＜0.05),红细胞平均血红蛋白浓度、中性粒细胞、中性粒细胞计数低于对照组(P＜0.05). 结论 磁场环境会对雷达站官兵外周血象产生一定的影响,应积极地采取防护措施对抗电磁辐射.“,”Objective To explore the effects of magnetic field on peripheral blood by comparing the peripheral hemogram of the soldiers and officers of radar troops and the personnel in physical examination.Methods One hundred and eighty-nine soldiers and officers of radar stations whose average age was (23.2±3.5) yr,radar working experience was more than 2 years and the habitation was in radiation area without any special protection measures,were selected as test group.Other 53 soldiers and officers who were received physical examination in Air Force General Hospital were selected as control group.Their average age was (21.3 ± 2.6) yr and they had no history of electromagnetic radiation exposure.The blood routine examination was done for 2 groups to compare and analyze the effects of magnetic field on peripheral blood.Results ① The abnormal rate of peripheral blood of test group was 60.90％.The hematocrit,mean corpuscular volume,mean corpuscular hemoglobin,mean platelet volume,red blood cell distribution width,lymphocyte,lymphocyte count was respectively higher than normal value,but the neutrophilic granulocyte was lower than normal value.The higher abnormal rate of lymphocyte,hematocrit,mean platelet volume,neutrophilic in test group was respectively 39.68％,21.69％,17.46％,17.46％.The abnormal rate of hematocrit and lymphocyte of control group was respectively 3.77％ and 5.66％.②The values of hematocrit,mean corpuscular volume,mean corpuscular hemoglobin,red blood cell distribution width,lymphocyte,lymphocyte count,eosinophil granulocyte,eosinophil granulocyte count,platelet hematocrit,mean platelet volume and platelet distribution width of test group were higher than those of control group (P＜0.05).The values of mean corpuscular hemoglobin concentration,neutrophilic and neutrophilic count were lower than those of control group (P ＜ 0.05).Collusions The magnetic field environment has resulted in a certain impact on the peripheral blood of the soldiers and officers of radar troops.Active protective measures should be taken to protect magnetic radiation.
