中国原子能科学研究院于2002年9月研制成功世界上体积最小、重量最轻的自屏蔽式电子束消毒灭菌装置,用于邮件的灭菌处理。 该装置利用加速器的电子束产生高能电子,辐照在被照射物体上,当电子束的剂量达到足够高 China Institute of Atomic Energy in September 2002 successfully developed the world’s smallest and lightest self-shielding electron beam sterilization device for the sterilization of mail. The device utilizes an electron beam of an accelerator to generate high-energy electrons which are irradiated on the irradiated object. When the dose of the electron beam reaches a sufficiently high level
