关于氚的生物危害性，在楼上Q&A页面中提供的详细信息pdf中，表示：
Biological impact of tritium
◇Animal tests and epidemiologic research to date have NOT shown “a far greater biological impact from tritium than other radiation or nuclides.
◇Mouse carcinogenicity experiments showed that even when mice continue to drink highly concentrated tritiated water (0.14 bilion becquerels/L),occurrence probability is about the same as that due to natural cancer occurrence.
◇No examples of negative impact attributable to tritium have been commonly seen among nuclear facilities.
(Ref.) Impact on human health of compound including tritium
●Tritium ingested in human body is excreted by metabolism and will be reduced with time.
◇Tritiated water ・Impact on human health is about 1/300 of that of Potassium 40(* Potassium-40 is a natural radionuclide abundant in foods such as vegetables and fruits.) ・Of the tritiated water that enters the body, 5% to 6% is converted into OBT(Organically Bound Tritium)
◇OBT (Organically Bound Tritium ・ Impact on human health of the OBT is less than 1/300 of that of cesium 137
综合来讲危害性与1/300的K40相当。
不过里面第二条，小鼠持续性摄入高度氚含量的水，竟然癌症发生率与自然发生率相当，这个有点没想到。不知道这个数据在国际上是否受到认可……
另附January 28, 2021发布的最新月度进度表，内容详实，就是字又多又小（看的头疼），想知道目前最新进展的看这个就没错了。当前同时进行的包括众多项目，这是在百度和新闻里看不到的。工程确实严谨，不管是工作量还是技术投入都确实是举国之力才能完成的，另外所有工作也都在国际原子能专家监督下进行，就目前来讲没有太大的硬伤了（当然历史遗留问题不算，现在巨大的工作量里有一部分就是倾国之力给之前擦屁股）。至少涨涨见识挺好，这种大工程不常见。
emmm不过最后那个工作人员尚未有确诊新冠的记录……怎么说呢，全日本截至目前累计检测数量不到1000万份样本，到底是真没感染的还是感染了没检查就不知道了……
