【欧洲核学会核新闻网(NucNet)2016年11月1日报道】美国国家科学院近日在一份报告中指出,在各国政府和供应商的共同努力下,医用同位素供应短缺现象已得到缓解,但供应仍很脆弱。报告表示,各国政府和供应商在2009—2010年供应短缺出现后采取的行动,加强了全球供应链的弹性,将生产堆和加工设施意外停产导致的供应不足影响降至了最低,并提高了医用同位素的使用效率。锝-99m是全球使用最广泛的医学成像放射性核素,目前主要通过钼-99的衰变来制备。由于这两种核素的半衰期都很短,不能长时间保存,因此必须定期生产并送至医
[NucNet, November 1, 2016] The National Academy of Sciences (NAL) pointed out in a recent report that the shortage of medical isotope supplies has been eased with the joint efforts of governments and suppliers. However, Supply is still fragile. The report said that actions taken by Governments and suppliers following a supply shortfall in 2009-2010 have strengthened the elasticity of the global supply chain and minimized the impact of shortages caused by the unplanned closure of production heaps and processing facilities Medical isotope use efficiency. Technetium-99m is the most widely used medical imaging radionuclide in the world and is currently predominantly produced by the decay of molybdenum-99. Due to the short half-life of both nuclides, which can not be stored for a long time, they must be produced regularly and sent to the hospital
