因此，存储是放射性废物管理重要的一步，尽管预计存储时间会有很大的不 同(如短效半衰期放射性核素会迅速衰减，因此，几个月后，就基本上消失殆尽； 有些同位素需要储存约三个世纪的时间；半衰期为24 000 年的钚可通过后处理 技术事先去除)。 daccess-ods.un.org | Thus, storage is an essential step in the management of [...] radioactive waste, although the targetedduration ofstorage will vary hugely (e.g., [...] radionuclides withshorthalf-lives will decay awayrapidly, so after a few months there will be essentially none left; a number of isotopes require storage for about three centuries; plutoniumwith a half-lifeof24,000years [...]can be removed beforehand [...]by using reprocessing technologies). daccess-ods.un.org |

特别是，与甲基汞40至50天的半衰期相比，乙基汞的半衰期很短（6天，95％CI：3-10天），这使乙基汞在血液中的暴露时间相对较短，同时，至少间隔四周才接种疫苗时就会防止出现累积情况。 who.int | In particular, thehalf-lifeof ethyl mercury is short(6 days; 95% [...] CI: 3-10 days) compared with 40-50 days for methyl mercury, [...]making exposure to ethyl mercury in blood comparatively brief and preventing accumulation when vaccines are administered at least four weeks apart. who.int |
