Dynamic Management of Radioactive Sources 

China implements a dynamic approach to managing radioactive sources from cradle to grave. Government regulation covers all actors working with radioactive sources. A national database on nuclear technology utilization has been established as part of the move to enhance the safety of radioactive sources, and the safety of nuclear technology utilization, with a special focus on the real-time online monitoring of high-risk mobile sources. As of June 2019, all 142,607 radioactive sources and 181,293 radiation devices in use were under regulatory control, as were all 73,070 entities engaged in the production, sale and use of radioisotopes and radiation devices. One hundred percent of radioactive waste has been safely stored. The annual rate of radiation accidents has continued to decline, from 6.2 per 10,000 sources in the 1990s to less than 1.0 per 10,000 sources in 2019, the lowest level in history, as a result of significantly enhanced safety in the use of nuclear technology. 

放射源的全過程動態(tài)管理

中國對放射源實(shí)行從“搖籃”到“墳?zāi)埂钡娜^程動態(tài)管理，將所有涉源單位納入政府監(jiān)管范圍，建立國家核技術(shù)利用管理數(shù)據(jù)庫，實(shí)施放射源安全提升行動，實(shí)現(xiàn)高風(fēng)險移動放射源在線實(shí)時監(jiān)控，提高核技術(shù)利用安全水平。截至2019年6月，中國在用放射源142,607枚，各類射線裝置181,293臺（套），從事生產(chǎn)、銷售、使用放射性同位素和射線裝置的單位共73,070家，放射源和射線裝置100%納入許可管理，廢舊放射源100%安全收貯。放射源輻射事故年發(fā)生率持續(xù)降低，由20世紀(jì) 90年代的每萬枚6.2起降至2019年的每萬枚1.0起以下，達(dá)到歷史最低水平，核技術(shù)利用安全水平大幅提升。
