关键词52：γ 辐照装置

γ 辐照装置是推动中国辐射科学技术研发和进入产业化发展的主要技术设备。相关科研生产单位，特别是北京三强核力和中国同辐旗下北京比尼公司坚持自主创新，研发出四大类γ 辐照装置，完成了三大国家标准，使中国γ 辐照装置的设计建造能力得到大幅度提升，成为获得国际认可的γ 辐照装置供货商。2015 年底，国产γ 辐照装置设计装源能力为30 万居里以上的钴源辐照装置达到130多台，国产大设计装源能力达到600 万居里，总设计装源能力超过1.7 亿居里，实际装源量约7000 万居里。主要用于食品辐照、中药辐照和医疗器械的辐照消毒灭菌以及部分材料改性。

Keyword 52：Gamma Irradiators

Gamma irradiators showcase the advances in the development of radiation technology in China and its industrial application. Relying on innovation, major players in this field, especially the Beijing SanQiangHeLi Radiation Engineering Technology Co., Ltd. (SQHL) and Beijing Bini, a subsidiary of the China Isotope & Radiation Corporation (CIRC), have developed four types of gamma irradiators, and created three national standards, greatly expanding China’s capacity to design and manufacture gamma irradiators, making China an international supplier of gamma irradiators. By the end of 2015, more than 130 cobalt-60 irradiators with a design capacity of more than 300,000 Curies were produced. The largest domestically made irradiators come with a design capacity of 6 million Curies. The gamma irradiators in use have a total design capacity of over 170 million Curies and an actual capacity of about 70 million Curies. They are used mainly for food irradiation, traditional Chinese medicine irradiation, disinfection and sterilization of medical equipment, and materials modification.
