【日本《辐射与产业》1984年第29号第16页报道】大剂量γ射线以前主要用于医疗器械的杀菌消毒、辐引化学反应和食品的保鲜,最近已扩大到反应堆材料的健全性试验,反应堆和人造卫星等的机器部件的耐辐射试验,以及果蝇的不育化处理。日本国内的钴-60辐照设施,中小规模的数量正在减少,而大型设施正在增加。 [Japan’s “Radiation and Industry”, 1984, No. 29, page 16 reported that high-dose gamma-ray was previously mainly used for sterilization of medical equipment sterilization, radiation chemical reactions and food preservation, has recently been extended to the robustness of the reactor material test , Reactors and satellites and other machine parts of the radiation resistance test, and the flies infertility treatment. The number of small-scale and small-scale cobalt-60 irradiation facilities in Japan is declining while large-scale facilities are on the increase.
