Tritium is the mildly radioactive isotope of hydrogen that has two neutrons and one proton, with radioactivity so low that no environmental or human problems have ever come from it, even though it is a common radioactive element in the environment. Tritium is formed naturally by atmospheric processes as well as in nuclear weapons testing and in nuclear power plants. Let’s say that again – no harm has ever come to humans or the environment from tritium, no matter what the concentration or the dose. Tritium emits an incredibly weak beta particle that is easily stopped by our dead skin layer. It only goes a quarter inch in air. Even ingestion of tritium doesn’t do anything. Cosmic rays produce four million curies worth of tritium every year (150,000,000,000,000,000 Bq) in the upper atmosphere, much of which rains out into surface waters that we end up drinking. Typical cosmogenic tritium concentrations in seawater are about 700 Bq/m3 (19 pCi/L) These amounts of tritium from other sources are millions of times greater than what would be slowly released from these tanks at Fukushima.
The biological half-life of tritium in fish and marine life is even shorter than in humans, less than 2 days, and the dilution in seawater is too rapid for any significant dose to get back to any people because the physical and chemical properties of tritium mean it does not concentrate up the food chain - it dilutes up the food chain. So while Japanese fishermen fear this strategy of release from a public relations perspective, their fish will still test negative with respect to food radiation limits and their packaged fish sold at market would still carry the official 'safe' stickers.
These contaminated water containers can be shipped to chernobyl site and kept there. However Japan needs to pay storage cost. This is a practical and safe solution
这么恨独轮运来美国干啥？ 美国是被宗教迫害清教徒移民，在英国当地是异端，打败了英国军队独立出来，以三权分立理念建立的民主国家。 说独轮运，美帝头一号啊。 btw However some scientists say the water would quickly be diluted in the vastness of the Pacific Ocean, and that tritium poses a low risk to human and animal health. 洗澡没问题的 哈哈哈
tritium 会致癌，说tritum没危险的就是无知 Cancer is the main risk from humans ingesting tritium. When tritium decays it spits out a low-energy electron (roughly 18,000 electron volts) that escapes and slams into DNA, a ribosome or some other biologically important molecule. And, unlike other radionuclides, tritium is usually part of water, so it ends up in all parts of the body and therefore can, in theory, promote any kind of cancer. But that also helps reduce the risk: any tritiated water is typically excreted in less than a month. Some evidence suggests the kind of radiation emitted by tritium—a so-called beta particle—is actually more effective at causing cancer than the high-energy radiation such as gamma rays, even though skin can block a beta particle. The theory is that the low-energy electron actually produces a greater impact because it doesn't have the energy to travel as far and spread its impact out. At the end of its atomic-scale trip it delivers most of its ionizing energy in one relatively confined track rather than shedding energy all along its path like a higher-energy particle. This is known as density of ionization, and has been shown with the similar form of radiation called an alpha particle. https://www.scientificamerican.com/article/is-radioactive-hydrogen-in-drinking-water-a-cancer-threat/

呵呵，不光华人，所有媒体跟国家都会大肆渲染的。
没影响让写文章的这人每天去喝一碗原汁原味的
放你马的狗臭屁，谁说的低生物半衰期物质带来的辐射就是无害的？如果海水受到污染，水生生物排出氚快，但同时也在继续摄入氚，它是会达到平衡的。拿生物半衰期来说是简直就是赤裸裸的撒谎。
狗日的拿了哪的钱在这里洗地？
倒海里是国家原子能机构的建议。倒是日本死扛一直不倒。。
真是的。。。
污染水中的放射性元素，有的半衰期长达30年。 人再把辐射鱼吃了，画风太美。
他们想制造哥斯拉
强re，问出那种问题的人真是脑子秀逗了
海产不能吃了，河鱼可以吃，现在河鱼基本都养殖的
美国居然不管？
自作孽不可活， 就该让他们灭族，凭什么祸害全世界。
你这么舔，怎么不去喝和用那些核废水帮小日本减轻负担？
国际不制裁？再飙个原子弹过去吧还是
了解下非政府组织、NGO 的资金来源就知道那压根就是一个西方某些政治势力，主要是白左那一类的的外围
No no. The water is perfect for you to drink.
民主的核废水，独运轮会呛着喝的。日本人这次傻了吧。 不应该排大海，应该运到台湾香港海外华埠$50一杯卖。 保证畅销供不应求
你是从你口中的厉害国来的吗? 你们家的地下水比核废水还脏？
真形象！
忠诚不绝对，绝对不忠诚。。
观那妈妈被更红的粉红们怒怼有感～～
因为做单向的process简单，如果要做成循环使用的closed loop故障率高，日本那里核辐射还是很高，发生故障维修很贵，所以设计成这样
去年六月想排来着，主要是被日本国内的舆论怼回去了，那个时候全世界都关注疫情和美国大选呢。 今年是不排没其他招了吧。
不争论数据，我只想知道这件事把日本换成中国或者俄罗斯，无论这个废水危害大还是小、有没有危害，那些现在替日本洗地说五毛大外宣造谣的的家伙会怎么表演
喝来苏水都没问题的
这你错了。按照洋流的走向，最先影响的是北美西海岸。当年福岛事件，有科学家用计算机模拟过福岛核污染扩散的动态图。
日本也太TMD混蛋了。可以说是世界上最最畜生的一类。怎么骂他们都不过份。哈日舔日的断脊梁狗也是同一类的畜类。
就是氘水的含量高的水，氘水自然界里本来就有，日本排的那点量根本对环境产生不了影响。
没有任何证据表明日本排的所谓核废水会对环境有危害。但某国释放新冠病毒危害全世界是板上钉钉的事。
稀释后和稀释前能一样吗？浓硫酸不能洗澡，但无限稀释后就和普通水没区别了。
生在中国才是最倒霉的。
各位看看这个活生生的例子，核废水对生物的影响就是这样的喏，
已经晚期了
说话讲证据，把日本“核废水”危害环境的具体证据摆上来。某国新冠害死的人数可实打实的在那里。
现在正在放的电影啊～～
Ｇｏｄｚｉｌｌａ～～
废水有问题，是毋庸置疑的。没问题的话，日本回收技术很高的，回收循环一下废水，作工业用途，不难。
新冠和这事别搅和了，人类不容易，总得想办法活下去，和一部分作死害人的败类作斗争。
因为日本的所谓核废水是处理后达标的，里面的辐射量极少，一天喝2升都没事，稀释到太平洋里更是不会对生物有影响。
人家的废水处理的达到排放标准凭什么不让人家排？别的国家讲道理当然不说什么，不像某国偷换概念，胡搅蛮缠。
实际上环保组织也没少说，去年绿色和平组织就发表文章说了废水的危害， 这东西就像ｃｏｖｉｄ疫苗，谁都不知道到底会如何，都是用科学模型理论推断。 所以你不管相信哪边都有道理，只是那些只会破口大骂的，是绝对没道理的～～
达到排放标准就可以排放，就像工业废水废气达标后可以排放一样。
呵呵 工业废水都不敢说每天喝两升都没事。
你和你家人，你还可以说服你家乡的村长乡长镇长市长，喜迎无危害的日本废水。全部给你们。
全世界人民感谢您！
这个多半是在骗子岛上的日杂，极力给它的日本爹开脱
应该都给台湾人运去喝，台湾不是在干旱吗？taiwan can help，呵呵
日本海产品就出口给台湾就好
当年去到福岛核电站里面抢险的机器人都因为辐射不能工作了，你就知道那里面的核污染有多严重。 这个冷却水是直接冷却核岛的，再怎么处理也有很高放射性☢️
这次日本就想先鞠个躬就把坏事干了，倒是比信教的干了坏事再去忏悔好些，不过日本干的更坏罢了
冷却水还能排到大海里，等核岛堆芯融化了，东京区的地下水被核污染，就要不停鞠躬了
盖格计数器卖起吧，去加州海滩前先测一下
估计是
哪里买？这个英文是什么？要多少钱呀？
试想，土鳖国要是排137万吨核废水进大海，估计全西方舆论都要八国联军核平了中国吧。
去用核废水洗澡吧，没人拦着你
国名一换，骂帖上万。
精辟，说得太对了
哈哈哈哈
那些都是平时用来耍大刀的，别把这些权益斗士的话当真，真遇到这事，个个都闭嘴了
不知道说什么好，送你两个字吧。。傻 逼
如果中国排了，根本就不会出现在新闻里。或者干脆美军投毒。
太垃圾了 美国怎么这时候不出来谴责了？估计又默许了？
这种垃圾都不配有家人朋友 垃圾独轮运
正常运转的核电厂也要不停地向江河湖海里排放这种氚化水，也没有见大家大惊小怪。
核电厂的冷却需要水，这样就会不停的产生氚化水。这就是为什么核电厂都建在江河湖海旁边的原因之一。
考考大家，现在哪个国家建核电厂最起劲？
新闻随便搜搜到处都是，IAEA网上也有数据。 半文盲大妈们被螂房id带着节奏满世界乱跑 “也没有国际组织出来阻止” LOL

有个浓度的问题，这些氚化水的浓度并不高于正常核电厂排放的冷却水浓度。
你怎么知道？还有这种投放是如果实行就会一直持续几十上百年，聚集作用怎么办？可以说世界上没有科学家能够预测将来被人吸收的量和风险，但致癌作用是肯定的，还有其他健康风险。吸收这种放射性物质就等于体内到处都是辐射源，24/7辐射人体各器官。。。以前吸收了镭的女工夜晚身上都会发亮，美国很著名的案例
排放之前需要监测浓度的。 我没有给日本辩护，我只是说核电厂也在几十年上百年不停地排放这样的冷却水。为什么大家不担心呢。当年台湾人反对建核电站，被大家笑话到今天，以爱发电，不记得了吗？
有病得治。。。。
据说核废料洗澡可以加速轮子转速。。。
真想骂你，我素质好，忍住了。。。

哈哈，国籍互换，评论过万。
一直在干啊，只不过现在的储存能力见顶了。
抛开剂量谈毒性就是扯淡 这话题说一万遍了 水喝多了也中毒 你要不要把水也戒了？
爱党要归，隔着太平洋舔屁股太没诚意了
是啊，日本有没有绝对科学的证明给全世界人民，他们倒的辐射水剂量小到1百年无害？ 谁作孽谁举证啊，证明满意了才可以给日本许可啊 日本不能说，剂量可能无害，所以我就可以随便倒？ 那所有的化工厂都可以拉个横幅“抛开剂量谈毒性就是扯淡”，然后就可以污水到处倾倒了？lol
