用于研究目的的电子加速器产生的放射性和有毒气体是多项调查的主题，在某些使用条件下，必须采取特殊的预防措施，以将工作人员和公众的暴露减少到可接受的水平。当用于医疗目的时，类似的加速器在剂量率、总剂量和降低这些气体的预期浓度的治疗间隔方面存在使用限制。计算以典型的医疗用途方式在 25 MV 下运行的特定装置的大气环境。只有在涉及高剂量率、通风不良和长治疗距离的特殊情况下才会出现重大危险。
The production of radioactive and toxic gases by electron accelerators used for research purposes was the subject of several investigations and under certain conditions of use special precautions must be taken to reduce exposure of staff and public to acceptable levels. Similar accelerators when used for medical purposes have limitations on their use in terms of dose-rate, total dose and interval between treatment that reduce the expected concentration of these gases. The atmospheric environment about a particular installation operating at 25 MV in a manner typical of medical therapeutic use is calculated. Only in exceptional circumstances involving high dose-rates, poor ventilation and long treatment distances would any significant hazard arise.
