数据来自路透社新闻链接:https://www.reuters.com/world/asia-pacific/japan-release-fukushima-water-into-ocean-starting-aug-24-2023-08-22/ TOKYO, Aug 22 (Reuters) - Japan said on Tuesday it will start releasing into the sea more than 1 million metric tons of treated radioactive water from the wrecked Fukushima nuclear power plant on Aug. 24, going ahead with a plan heavily criticised by China. The plan, approved two years ago by the Japanese government as crucial to decommissioning the plant operated by Tokyo Electric Power Company (Tepco) (9501.T), has also faced criticism from local fishing groups fearing reputational damage. "I expect the water release to start on August 24, weather conditions permitting," Prime Minister Fumio Kishida said. The announcement comes a day after the government said it had won "a degree of understanding" from the fishing industry over the release of the water into the Pacific Ocean, even as fishing groups said they still feared the reputational damage would ruin their livelihood. The water will initially be released in smaller portions and with extra checks, with the first discharge totalling 7,800 cubic metres over about 17 days starting Thursday, Tepco said. That water will contain about 190 becquerels of tritium per litre, below the World Health Organisation drinking water limit of 10,000 becquerels per litre, according to Tepco. A becquerel is a unit of radioactivity. Japan has said that the water release is safe. The International Atomic Energy Agency (IAEA), the U.N. nuclear watchdog, greenlighted the plan in July, saying that it met international standards and that the impact it would have on people and the environment was "negligible".
Update: 新闻里的 “兆” 是 ‘trillion'' https://www3.nhk.or.jp/nhkworld/en/news/20230824_36/ The annual amount of tritium contained in the treated and diluted water to be released from the plant in Fukushima is capped at 22 trillion becquerels. Chinese nuclear energy sector data show the Qinshan power plant in Zhejiang Province released 218 trillion becquerels of tritium in 2021. That is about ten times the maximum amount of tritium to be discharged from the Fukushima Daiichi plant in a year.
另外,老是拿氚说事,其他的放射性元素也有。一月的报道,鱼里面的铯超标180倍。 Fukushima fish with 180 times legal limit of radioactive cesium fuels water release fears https://www.theguardian.com/environment/2023/jul/24/fukushima-fish-with-180-times-legal-limit-of-radioactive-cesium-fuels-water-release-fears
一家德国海洋科学研究机构指出,福岛沿岸拥有世界上最强的洋流,从排放之日起57天内,放射性物质就会扩散到太平洋的大半区域,3年后美国和加拿大将遭到核污染影响,10年后蔓延到全球海域,或导致人体细胞死亡和DNA损伤,影响到全球鱼类迁徙、远洋渔业、人类健康、生态安全等方方面面。 中国海洋法学会会长高之国对媒体表示,目前国际学术界有比较一致的观点,认为福岛核污染水中有64种核放射性物质。上海政法学院教授杨华指出,核污染水有巨大危害,日本将核污染水和核废水混为一谈,是偷换概念。中国海洋大学海洋生命科学院教授王悠认为,民众关注的不仅仅是日本当地的海鲜。如果环太平洋海域的渔场被波及,这些海域的海产品都会受影响。 日本工程技术专家后藤政志表示,放射性物质进入人体内后有各种破坏路径,比如铯会对甲状腺产生影响,锶会侵入骨骼,即使微量也会对局部器官产生很大破坏,发生局部癌变的风险增大。 今年7月,在韩国国会议员及渔业团体就核污染水排海举行的新闻发布会上,韩国最大在野党共同民主党议员、“阻止福岛核电站核污染水排海”对策委员长魏圣坤表示,尽管日本的排放计划持续30年,但带来的危害或将持续200年。
问3)日本政府认为“核污染水”处理后是安全的,为什么不把这部分水用于本国国内农业用水或产业用水等?
(答) 1 释放的水是将除氚以外的放射性物质充分净化至监管标准以下的水。进一步稀释后,氚以外的放射性物质的浓度将低于监管标准的1/100。氚的浓度也将被稀释至监管标准的1/40,WHO饮用水标准的约1/7,不会向海洋释放超过监管标准值的水。 2 该水虽然满足放射性物质的监管标准,但由于使用大量的海水进行稀释,含有盐分,因此不适合作为一般饮用水、产业和农业用水等。 3 另外,日本和国际上都没有将核设施的废水排到土壤、并对其影响进行准确地监测的经验,而且也没有建立追踪放射性物质的后续行为的监测方法。 4 而且,中国也和日本一样,根据IAEA制定的国际标准,从原子能设施向海洋排放含有氚等放射性核素的废水。日本预计释放入海的ALPS处理水中氚的排放量为每年22兆贝克勒尔,这是中国浙江省的秦山核电站每年排放量的约十分之一,广东阳江核电站、福建宁德核电站,以及红沿河核电站每年排放量的分别约五分之一。 ※1 中国原子能设施的氚(液体)的年排放量(2020年和2021年) 核电厂放射性流出物排放情况 (2020年) ・秦山第三核电站 143兆贝克勒尔 ・阳江核电站 122兆贝克勒尔 ・宁德核电站 111兆贝克勒尔 ・红沿河核电站 107兆贝克勒尔 (2021年) ・秦山核电站 218兆贝克勒尔 ・阳江核电站 112兆贝克勒尔 ・宁德核电站 102兆贝克勒尔 ・红沿河核电站 90兆克勒尔 ※1-4号机组、5-6号机组的合计 (出处:中国核能年鉴2021、2022)
别拿标准话术洗地了。
就拿氚说事,氘氚海里面本来就都很多。日本的切尔诺贝利——福岛七级核事故里面其他的乱七八糟的放射性元素呢?正常核电站可没有那些。
各种长半衰期的放射性,是不是都需要稀释几千倍才能达到排放标准?ALPS是不是三天两头出问题?
就地掩埋呢?或者能不能在日本海边专门建一个蓄水池,让海水慢慢蒸发? 日本这个废水里面放射性最严重的是重粒子,h2 h3这些放射性本来就很小,海水里面就有很多,可以被用来做核聚变原料,所以才说核聚变是真正的取之不尽用之不竭的能源
就地掩埋 ,这些不就留在本土了吗。 。。。。。人家心里算盘打的很清楚。 估计也就开始还有人闹腾,时间长了,大家就都无所谓了。
那位不知道是正宗日本人还是日本人的孙子台湾鬼子
可以做游泳池水,这么好就挖个大游泳池留给日本人自己享用吧。
如果还年轻我觉得还是忍了吧,如果是快入土的那就放开吃呗
一瓶矿泉水掉马桶里了,只要瓶子没破,洗一洗瓶子,除了有些膈应里面的水拿来喝没太大关系。 拉了一坨大便的马桶水,你喝吗? 你说大便浓度高!倒一浴缸水下去不就稀释了吗,来抗回去慢慢喝
中国也是国际原子能机构的重要成员,完全可以通过正常渠道发声反对。
好精准
你太神了

这个 “每年22兆贝克勒尔” 是怎么算出来的?
按下面这个路透社新闻给的数据,按目前的排量,一年氚的排放量将比 “22兆贝克勒尔” 的 1000 倍还多
初期每日排放污水 (单位:升,litre):7800 * 1000 / 17 污水中氚含量 (单位:贝克勒尔/升,becquerels / litre):190 初期排放量:smaller portion,意思小于年平均值
那一年排放的 氚 (tritium)将是 (单位: 兆贝克勒尔):365 * (7800 * 1000 / 17 ) * 190 / 10^6 = 31819
如果1兆算10^6, 年排放量 31819 Mega becquerel 将远大于 22 兆贝克勒尔。

据说可以采取蒸发后深埋残渣的办法,但小日本嫌弃太费钱了……
其实抗议了的,上个月NPR等等左媒有很多采访报道

有人说日本2013年就已经泄漏了大量,还有人说中国大亚湾更严重,中国事故隐瞒了。我想这是可能的。反正不管怎样,那也说明海洋里面越来越富集了。现在的总比以后的好点。所以以后,越来越不能吃了。
我怀疑今后:餐馆外卖是不敢吃了,谁知道他们用的什么海鲜和盐;零食和半制成品也不敢买了,谁知道他们用的什么原料;酱油和醋都只有自己酿造了,不然里面的盐也没法保证啊。。。华人有必要成立一个自己动手丰衣足食版。。。
唉,以后活得越来越辛苦。而且更要命的是会有更多疾病的困扰
除了氘还有其他的放射性元素怎么不提?那些可是对人体有害的,你所谓的稀释不就是在玩数字游戏?反正核电站方圆十公里范围内还是无人区,为什么不把那里改造成污水排放区?那里空气中的辐射可都是超标的
核污水和核废水是两个不同概念。正常核电厂排放的核废水,放射性低,可排入大海。福岛的核污水是堆芯融毁后直接触造成的污水,放射性高,就算稀释以后改善也不大,因为污水总量过高。福岛的核污水里面的放射性物质,除了氚,还有铯锶。铯锶半衰期是30年,足够污染海洋和鱼类。吃到污染的海产品,铯锶会停留人体的肌肉和骨骼中,形成内照射致癌。即使经过100年的衰减,铯锶还残留大概10%,足够影响到到孙子辈。
切尔诺贝利当年是封存到地下的。日本也可以把核污水浇筑在水泥,然后埋地下封存,但这样做的成本远高于排放到大海。核污水排放大海的史无前例,所以说给日本洗地的不是无知就是居心不良。
谁觉得这水安全,免费life time 私家供应。
终于有个科学的帖子,不是屁股决定脑袋。
日本排放的不仅是泡过也是过滤过的,所以相当于大便提取液,比你洗脚水干净多了。跟不讲科学的人蠢货沟通真是累。
外务省7000亿日元的排污公关费,你有拿多少?给点渠道,大家一起挣点外快花花。
这地洗的好干净
