目的：医用电子直线加速器是目前最常用的放射治疗设备,医用电子直线加速器在肿瘤放射治疗中起主导作用,并取得了相当可观的疗效。分析医用电子直线加速器在正常工作条件下、异常情况下的辐射危害,保证对放射工作人员不会产生确定性效应,发生的随机性效应概率能够控制在可接受的水平。方法：通过制定并全面落实、严格的操作规程和规章制度,强化工作人员安全意识以及配备完善、有效的防护设施,以避免或降低事故照射发生的概率。加速器工作场所进风、排风口的位置设计要合理,风机功率须符合要求。加速器及其工作场所应具有良好的屏蔽设计和多重监控、联锁系统,以保障正常运行的安全。结果：医用电子直线加速器感生放射性辐射水平与加速器的能量、剂量和停机后间隔时间等因素有关。放射性工作人员在医用加速器正常工作条件下受照剂量较低。结论：医用电子直线加速器在正常工作条件下,对放射性工作人员不会产生确定性效应,发生的随机性效应概率能够控制在可接受的水平。
