小型钴源装置安全管理及利用研究

Research of Utilization and Safety Management of Minitype Co Radioactive Source

小型钴源的安全管理,通过中心控制室实现运行管理,设计了控制管理,输入输出装置,安全管理过程控制硬件和软件保安措施,确保运行安全可靠。钴源活度为5×104Ci。利用钴源装置,"八五"到"十五"期间,开展辐射诱变育种研究,推广高产、抗病、早熟农作物品种13个,累计推广面积600万hm2,增收27亿多元;开展辐照加工工艺研究,推广农副产品辐照加工,辐照中成药杀虫灭菌,辐照医疗器械等技术,新增产值1.2亿元。

The safety of the minitype equipment of Co radioactive source is managed by control center.The technicians design procedures for management,input the data,make measures to guard hardware and software,in order to make sure the equipment operates safety.The radiant intensity of Co is 5×104 Ci.With this equipment,the research of irradiation breeding in the period of ＂the Eighth Five Years Plan to the Tenth Five Years Plan＂popularized 13 breeds of cropper which were high-yield,disease resistance and precocity.The popularization acreage was 6×106 hectare.The production increases more than 3×109 kg,and the income increases more than 2.7×1010 yuan.It was useful to develop the irradiation processing technique,research the irradiation of farm and sideline products,and use this method in sterilization or disinfection.The technology of sterilization with the irradiation medical device could increase the output value about 1.2×109yuan.
