They have lied for all those years years to the people from who they needed the permission before any dumping ( fishermen associations, local government, etc.) that all radionuclides had been filtered out, that it was only tritiated water. We have to wonder what is forcing them suddenly to admit this.
Treated water at Fukushima nuclear plant still radioactive
Treated water at Fukushima nuclear plant still radioactive: Tepco
Kyodo News wrote about a new admission at Fukushima Daiichi. The ALPS water decontamination systems are not removing almost all of the contamination as previously claimed. TEPCO admitted new levels of specific radioactive isotopes in the treated and stored water.
Iodine 129 has a half life of 15.7 million years
Ruthenium 106 has a half life of 373.59 days
Technetium 99 has a half life of 211,000 years
All are considered to pose enough of a public health risk that they need to be controlled. Iodine 129 levels found in the water samples exceeds the legally admissible levels. The other two isotopes fall below the legal level. The considerable total amounts of these radioactive substances make them a concern.
Total post ALPS water: 920,000 tons of water
1,000 liters per ton
920,000,000 liters total
Newly admitted levels of contamination along with our calculated totals:
62.2 bq/liter iodine 129 = 57,224,000,000 bq
92.5 bq/liter ruthenium 106 = 85,100,000,000 bq
59 bq/liter technetium 99 = 54,280,000,000 bq
Total of newly declared becquerels of contamination:
TEPCO has been trying to gain the needed permissions to dump this water into the Pacific ocean, claiming it only contained tritium and trace amounts of other isotopes. The actual radioactive isotope contents of the treated water has not been clearly declared to the public. Statements like “removes almost all” or only mentioning the removal rate of a specific isotope has been the standard pattern of disclosure. This has left questions about what exactly is in this water they are so eager to dump. TEPCO’s reluctance to be more transparent about the contamination in this water raises concerns they are hiding information.
Regional fishing groups have fought the dumping plan claiming it would hurt seafood sales. This issue of undeclared contamination or the environmental ethics of dumping it into an international body of water are rarely discussed. TEPCO mentioned they have not tested all of the tanks of treated water. The estimated totals we compiled could go up or down based on what is found in those untested tanks. TEPCO did not disclose the process of selecting tanks or how many of the total have been sampled.
The plan to dump the water into the ocean has been based on the claim that this water only contained tritium. With a half life of 12,3 years, this alone seemed a problem the public might tolerate. The addition of these long lived isotopes makes any potential plan to store the water while the tritium decays problematic. The removal of these other isotopes will need to be proven before any long term plan can realistically be determined.
Water at Fukushima nuclear plant still radioactive even after treatment, Government wants to dump the contaminated water into the sea, but locals and fishermen oppose the idea.
ALPS system at Fukushima No. 1 plant failing to remove more than tritium from toxic cooling water
More than 200 Japanese scientists and citizens decleared “A Resolution Against the Ocean Dumping of Radioactive Tritium-contaminated Waste Water From the Fukushima Nuclear Power Plant.”
Copied below is the document or see the following website:
Please read it and you could take the situations more seriously how dangerous it can be if TEPCO dumps as
planned the tritium-contaminated water from the defunct Fukushima nuclear plant to the Pacific Ocean.
If you could post this document onto your web-pages or blogs and share it with your friends and acquaintances, it would be very helpful to spread the real picture of Fukushima nuclear disaster, that the Japanese government wants to conceal by any nasty means.
Physics Professor Emeritus at Kyoto University, Kosaku Yamada, who led the process to declaring this resolution, hopes that everyone who agrees with this resolution could e-mail him and register as an assenter of it.
With greeting of solidarity,

A Resolution Against the Ocean Dumping of Radioactive Tritium-contaminated Waste Water From the Fukushima Nuclear Power Plant(pdf,3pages,146KB)
It was announced in March, 2014, that in the defunct Fukushima Nuclear Power Plant there was a total of approximately 3,400 trillion becquerels of tritium, with 830 trillion becquerels stored in tanks. This enormous amount of radioactive waste water has still continued to increase since then. In these circumstances, the Japanese government and Tokyo Electric Power Company Ltd. (TEPCO), in their efforts to find an easy way to dispose of the tritium-contaminated waste water created by the Fukushima nuclear disaster, have been trying to dilute and dump it into the ocean. They have been watching for an unguarded moment among the opposition movements, such as fishery cooperatives. Now they are about to finally decide to implement the ocean dumping plan. Far from regulating such activities, Toyoshi Fuketa, the chairman of the Nuclear Regulatory Authority has been championing this plan.
We are determined that the Japanese government and TEPCO shall never dump the radioactive waste water into the ocean for the following reasons:
1. Generally misunderstood as posing little risk to life and health, tritium is an extremely hazardous radioactive material. This is because organisms are not able to chemically distinguish tritium water from the normal water which composes most of the human body. This means that tritium can invade any part of the human body, irradiating it from inside; therefore, tritium can damage cell membranes and mitochondria in cells, indirectly through reactive oxygen species (ROS) and other radicals generated in irradiation. Tritium decay can directly cut chemical bonds of genomes or DNA strands. The risk peculiar to tritium is that if some hydrogen atoms which make up the genomes are replaced with tritium, the beta decay of the tritium into helium will cut off the chemical bonds of the genome.
Plants produce starch from water and carbon dioxide gas by using photosynthesis. Some of hydrogen atoms in this starch can be replaced with tritium, forming organic tritium, which animals, plants and human beings absorb into their bodies over the long term, causing internal radiation.
2. With reference to the tritium released by various nuclear facilities, reports indicate a number of findings including: an increased incidence of leukemia among those living around the Genkai Nuclear Power Plant; an increased incidence of infant leukemia around nuclear reprocessing plants all over the world; and an increased incidence of child cancers around nuclear power plants. Real damage has already occurred.
3. Tritium, even if diluted and dumped into the ocean, will become concentrated again through aspects of the ecosystem such as food chains. Furthermore, tritium will vaporize into tritium-containing moisture or hydrogen gas only to return to the land and eventually circulate within the environment. The idea that dilution ensures safety has caused fatal blunders to be repeated in many environmental pollution cases in the past, the vital factor being the total quantity released into the environment. Therefore, as far as environmental pollution problems are concerned, the only righteous and principled policy is to thoroughly confine and isolate radioactive materials or toxic substances from the ecosystem.
As tritium has a long half-life of 12 years, it destroys the environment over the long term. Tritium is an isotope of hydrogen which constitutes not only most of the living body but also its genes, so tritium disposal via dilution cannot be safe. Thus, we strongly urge the Japanese government and the Nuclear Regulatory Authority never to dump tritium into the ocean.
