“I am filled with excitement, thinking, ‘At long last. David McNeill reports from Soma City (There is nothing positive about that rationale. he said. Neither alternative has been pursued for various unstated reasons. Chernobyl is a prime example of this latent impact of radioactive exposure, to wit: A BBC special report, “The True Toll of the Chernobyl Disaster,” dated July 26 2019 explains: “The official, internationally recognised death toll, just 31 people died as an immediate result of Chernobyl while the UN estimates that only 50 deaths can be directly attributed to the disaster.” Keep those two numbers of deaths, 31 and 50, in mind while reading ahead. Along those lines, it is important to note that ocean disposal of nuclear/radioactive waste has been banned via international treaties, e.g., The London Convention bans dumping radioactive waste in the seas. According to estimates made immediately after the accident in 2011, there were reports that the inventory of 3H at the time of the accident was 1.81 × 1013 Bq8, but according to recent reports by Tokyo Electric Power Company Holdings (TEPCO), the inventory of 3H immediately after the accident was estimated to be 1.0 × 1015 Bq at Unit 1, 1.2 × 1015 Bq at Unit 2, and 1.2 × 1015 Bq at Unit 3, for a total of 3.4 × 1015 Bq4. Japan Says Fukushima Leak Worse than Thought, Government Joins Clean-up Highly radioactive water from Japan's crippled Fukushima nuclear plant … Also, since the samples were collected approximately 1 month after the accident, the 3H on the ground most likely originated as precipitation from the atmosphere, not via groundwater. Akimoto has worked hard to keep it afloat, negotiating with the central government and plant operator Tokyo Electric Power Company on decontamination work and compensation. “In the past, it has been seen that radioactive material discarded in France travelled to the North Atlantic and Arctic Oceans and found in the bodies of seals and Tortoises,” he said, warning that South East Asian nations will be at higher risk. Three reactor buildings were severely damaged by hydrogen explosions. The concentration of 137Cs ranged from 3 to 4 Bq/kg, and the ratio of 134Cs/137Cs radioactivity at the time of the accident was almost 1. “Our mission is to take good care of our hometown forests and enhance the surrounding environment,” says Akimoto on the day his cooperative returned to Tomioka. However, he also remarked that the decision per se is within the domain of sovereignty, making it clear that Japan has no intention of discussing the issue. To date, the Japanese government has not indicated it will allow independent testing of treated water. Still, she says, that doesn’t help to raise hope amid the coronavirus pandemic and the delayed recovery of the disaster-hit Fukushima region. Robert Hunziker: It is a direct consequence of the 2011 meltdown. Rather, the ocean will simply carry radioactive ingredients to the shorelines of other countries. By summer of 2022, the 1,000 huge storage tanks will reach their full capacity, and the water will be treated, diluted, and released into the Pacific Ocean over several decades, the reports said. Sputnik: Does Japan have a plausible alternative to continuing to make use of nuclear power? 3257 Dunmore Rd SE Medicine Hat, AB T1B 3R2 [P] 403.527.1101 [F] 403.528.5696 They claim that tritium, the main remaining radionuclide after processing, will dilute, emphasising the fact that it is relatively harmless to humans. But after nine years and eight months, it returned to Tomioka on November 4. The tritium beta energy is low (max 18.6 keV), and requires large quantities to deliver significant radiation doses, so that the measurement of other nuclear species was prioritized when considering human protection immediately following the accident. Citing studies from the World Health Organisation, M C Misra, former director of AIIMS, Delhi, said an increase for specific cancers for certain subsets of the population inside the Fukushima Prefecture is very likely. At the end of its atomic-scale trip it delivers most of its ionising energy in one relatively confined track rather than shedding energy along its path like higher-energy particles. Therefore, it was estimated that the tritium in the groundwater from the flowing-well had an age of nearly 40 years.

It said it will keep in contact with Japan to obtain necessary information. Investigation of 3H in precipitation may be one of the easiest ways to confirm the release of 3H into the atmosphere. Fukushima 2020 | Fukushima Daiichi, Radioactive Water, Sea release, South Korea | However, it seems that they are making no effort to get land. That is not an overstatement. The khaki green control equipment, dating back to the 1970s, is still in the room, though long rendered unusable by the disaster. Concerns related to the environment and health are crucial for the existence of the human race. “Human rights experts: the threat of nuclear radiation in Fukushima is still there; the government should stop the home return policy”, UN News, October 25, 2018. “TEPCO said it could take out the fuel debris of No.2 of the Fukushima nuclear power plant”, Observer Network , February 14, … Some suggested alternatives include evaporating the water into the atmosphere or mixing it into concrete and storing it underground. Fukushima 2020 | Fukushima Daiichi, Radioactive Water, Sea release, Taiwan | Isn’t it possible that the level of radioactive discharge being released will simply be diluted by the ocean and won’t dangerously contaminate sea life and the food chain? It has been revealed that, in 70% of the tanks, the amount of radioactive substances present is 20,000 times the standard. However, Fukushima is a land-based discharge. As much as 400 tons per day was gushing in just a couple of years ago. http://www.arirang.co.kr/News/News_View.asp?nseq=268158, A top-ranking official at the Japanese Embassy in South Korea on Friday mentioned Japan’s plan to release contaminated water that was used to cool the the first nuclear power plant in Fukushima in an interview with South Korean journalists, saying, “It is too early to affirm the plan but it may be specified within this year. Non-Olympic sites throughout Japan averaged 7.0 times greater beta activity than the Tokyo Olympic venues. In contrast, Olympic sites in Northern Japan near Fukushima contained an average of about twice as much radioactivity as Tokyo, with Plutonium identified at the J-Village National Training Center. Solutions are already at work and fully operational for all to see in the field. But land [see picture] immediately adjacent to their property is EMPTY and too radioactive to be sold. The released amount was estimated to be approximately 520 PBq1, with radioactive iodine (mainly 131I), radioactive cesium (134Cs, 137Cs), and noble gases such as 133Xe accounting for most of the released amount. However, isn’t that like letting the fox into the hen house to check security and safety? Japanese fish industry representatives on Thursday urged the government not to allow the release at sea of tonnes of contaminated water from the Fukushima nuclear plant, saying it … Fukushima nuclear disaster: Lethal levels of radiation detected in leak seven years after plant meltdown in Japan The Tokyo Electric Power Company … Environmentalists and several organisations, including Safecast?and Greenpeace, have urged the Tokyo Electric Power Company (TEPCO), the operator of the Fukushima plant, to build more storage tanks and keep the water stored. It was clear that there was no direct correlation with the radioactivity of tritium contained in the leachate compared with the respective construction periods. Based on tritium data published by Tokyo Electric Power Company Holdings (TEPCO) (17,000 points), the postulated source of the leakage was (1) leaks from a contaminated water tank that occurred from 2013 to 2014, or (2) a leak of tritium that had spread widely over an impermeable layer under the site. Sputnik: According to a report given to the IAEA by Japan, analysis by the power company of sea and groundwater shows “confirm that the radiation level of sampled water is substantially below the operational targets set by TEPCO”. No Nukes Action hosts an international panel on the Olympics, Fukushima and the Madness. Robert Hunziker: That is questionable. The council reached out to the Japanese government in September 2019 and March 2020 to ask about the situation and remind Japan to share timely information about the situation in accordance with a memorandum signed between the two countries in 2014. “Tritium is a beta emitter with low energy so causes damage to the DNA leading to genetic damage and affecting reproductions.” It will depend upon the radioisotopes contaminants in the water. “We will help lay the groundwork to ensure residents can return worry-free. Deposition of the radioactive elements on the rocks has also to be seen,? In a meeting of the Nuclear Regulation Authority (NRA) in June, one of its members, Nobuhiko Ban, told TEPCO officials, "I want you to show whether you have a prospect (for the reduction of contaminated … Pictured: a rally in front of the Japanese Diet on October 27, 2020. The content is provided for information purposes only. The park is a main setting of Yu's award-winning novel, “Tokyo Ueno Station,” in which the protagonist, Kazu, a seasonal worker from Fukushima… (Photo: The damaged Fukushima Daiichi Nuclear Power Station as seen during a sea-water sampling boat journey. I didn’t even imagine things were so bad,” says forester Akimoto Kimio, who visited a plantation in Tomioka, about 10 kilometers away from the crippled Fukushima Daiichi nuclear power plant. Fukushima remembered, three years later 21 photos TOKYO -- After battling radioactive water leaks for five years at Japan's crippled Fukushima Dai-Ichi … (Source: Shaun Burnie, senior nuclear specialist for Greenpeace). The greater Tokyo Olympic venues had activities similar to sample sites in the US. Japan’s nuclear regulator has maintained its view that multiple blasts occurred at the Fukushima Daiichi nuclear power plant’s No.3 reactor following the earthquake and tsunami in 2011. Meanwhile the radioactivity of tritium in flowing water was below 0.01 Bq/L. The concentration of 3H in the sump water collected at the sites indicated by asterisks in Fig. 3 is shown in Fig. 4. September 12, 2020 September 12, 2020 Kaleidoscope's House of Broken Glass. Leave a comment. Viktor Sushko, deputy director general of the National Research Centre for Radiation Medicine based in Kiev, Ukraine, described the Chernobyl disaster as: “The largest anthropogenic disaster in the history of humankind”. Nine years ago, on March 11, 2011, a magnitude 9.0 quake and tsunami destroyed key cooling functions at the plant, causing a meltdown that leaked a massive amount of radiation and forcing some 160,000 residents to evacuate. As it stands, says the report, it looks like 72% of the water currently in storage tanks will have to be processed again – and questions remain as to how effective this will be. TEPCO and their experts say tritium is not necessarily dangerous, assuming enough dilution of the isotope; however, there is evidence to suggest beta particles emitted by tritium are more effective at causing cancer than high-energy radiation such as gamma rays. A contaminated forest would be particularly hazardous in the event of a landslide, because the mud flow is likely to contain radioactive substances. The entrance of Futaba town, which has been empty since the leak at the nearby Fukushima Daiichi nuclear power plant in 2011. Neither your address nor the recipient's address will be used for any other purpose. (By Fan Cheng-hsiang and Chiang Yi-ching), https://focustaiwan.tw/society/202011090021, November 15, 2020 This approach was recommended by scientific advisers and approved by the International Atomic Energy Agency (IAEA). The council has also conducted tests to monitor the level of tritium in Taiwan’s surrounding waters and found that current levels are normal, it said. In addition, the sump water also contained radiocesium (134Cs and 137Cs). 11 wells, the tritium levels tended to decrease monotonically from a peak in April 201421. In this study, we report that 3H above natural levels has been detected continuously in groundwater sampled from 2013 to 2019 on land approximately 30 m from the FNDPP site boundary. Japan Fisheries Cooperatives and Fukushima Prefectural Federation of Fisheries Co-operative Associations have unanimously passed a resolution stating that they “firmly oppose the disposal of contaminated water into the sea”.Â, Japan’s fisheries firmly oppose the dumping of radioactive water from the Fukushima nuclear site into the Pacific Ocean. “It’s regrettable. On 21 October 2020, Japan provided the IAEA with a copy of a report on the discharge record and the seawater monitoring results at the Fukushima Daiichi Nuclear Power Station during September, which the Ministry of Foreign Affairs has sent to all international Missions in Japan. ), A panel of experts advised TEPCO that dumping it into the ocean is the most “realistic option.” (Experts are readily available for anything and everything. TEPCO claims that it will dilute tritium-contaminated water to below standard level and dispose of it into the ocean; however, the absolute quantity of tritium in the water has not changed, and it is pointed out that tritium’s dangerous effects of bioaccumulation of radioactive material in fish can be seen throughout the food chain. See Potassium-40. November 22, 2020. On February 4, 2020, Japanese authorities held a meeting with embassy officials where they tried to convince the latter of the advantages of the plan to release radioactive water from storage facilities at Fukushima. and Terms of Use. Any such disposal now of water into the sea would be an act of betrayal to the fisheries. Contaminated water that could soon be released into the sea from the Fukushima Daiichi nuclear power plant contains radioactive carbon with the … The 3H observed in sump water ranged from 15 to 31 Bq/L and was almost constant (average 20 Bq/L). Officials say the state of buckled beams on the third floor indicates an instantaneous wind pressure of up to 5 atmospheres. Misra, who has dealt with all types of medical cases, including that of radiation, said Japan could have easily prevented the entire accident. Leave a Reply Cancel reply. More than seven years after the March 2011 Fukushima nuclear crisis, radioactive water is continuing to flow into the Pacific Ocean from the crippled No. The land-side water impermeable wall (frozen soil wall) and the sea-side water impermeable wall (steel sheet pile) were installed to surround the circumference of the FDNPP and prevent 3H flow off site. But issues still … Fukushima 2020 | Fukushima Daiichi, Radioactive Water, Tritium leakage | “As of January 2018, 1.8 million people in Ukraine, including 377,589 children, were considered victims of the Chernobyl nuclear meltdown, according to Dr. Sushko. Robert Hunziker: According to numerous sources, dumping Fukushima Daiichi’s radioactive water into the Pacific Ocean will start in 2022 and continue for decades. The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident released a large amount of radioactive materials into the environment since 2011. A key aspect of this study is that the water examined was groundwater, not surface water. The half-life of cesium is 30 years, it will take 30 years of half of the material to decay. Japan Experts: Fukushima’s melted reactor cores “still active and releasing neutrons” many months after 3/11 — Radioactive sulfur was “the highest ever measu... Canine Tooth Mountain Lion However, it is estimated that there is 1.8 × 1015 Bq of tritium that has not been identified in the turbine buildings and in contaminated water, in addition to the amount released outside after the accident or the amount in debris10. Furthermore, there have been instances of storage tanks leaking highly contaminated water. On March 11, 2011, a 9.0 magnitude earthquake struck off the north-eastern coast of Japan, triggering a 15-metre tsunami that damaged the 5,306 MW Fukushima nuclear plant. Cumulate 3H yields in the reactors at FDNPP have been estimated to range from 0.01% to 0.0108%6,7. This posturing by TEPCO is where the “rubber meets the road”, splitting world opinion into two opposing or warring camps. However, in August 2018 Japanese media reported that ALPS had consistently failed to eliminate a variety of other radioactive elements, including iodine-129, ruthenium-106, and strontium. Japan has been slow to admit the scale of the meltdown. Therefore, over 1.2 × 1012 L of water would be required for dilution. Dilution is not the solution to pollution! On Thursday, the Nuclear Regulation Authority along with experts analyzed images taken at the No.3 reactor. Also the half-life of tritium is 12 years,” he told PTI. Cesium has a half-life of 30 years and will be the last to decompose,? He believes forest preservation will one day help to ensure evacuated residents can return. This inconspicuous loophole in language provides weird (questionable) comfort to Fukushima Daiichi to violate the ban on dumping radioactive waste at sea. Tritium (3H, T1/2 12.3 y.) But there was nothing they could do to stop reactors one, two and three from melting down. More than 70 percent of the prefecture is covered with trees, but large areas have been abandoned or neglected. There is strong opposition abroad. The Japanese PM Suga is still saying the Olympics will go ahead regardless of the Covid-19 worldwide pandemic and the continuing threat of the broken and leaking nuclear plants in Fukushima. Some of its most prized pine trees, more than 50 years old, have died. ), The IAEA (International Atomic Energy Agency) approves it. The relevance will be discussed, including the results of detailed tritium measurements in the water collected inside/outside FDNPP site. At the FDNPP, four measures have been taken to prevent surface water from infiltrating into groundwater25.. Additionally, groundwater flows into and out of the basements of the reactor buildings from which some contaminated water leaks out into the soil and surrounding groundwater beyond the facilities. These children have a range of illnesses: respiratory, digestive, musculoskeletal, eye diseases, blood diseases, cancer, congenital malformations, genetic abnormalities, trauma.”. Among them, direct releases to the ocean and releases to the atmosphere have been reported in detail. Singh, among the Indian government’s top nuclear health scientists, said the release of contaminated water into the ocean will directly impact human and aquatic life. This is great.’ It is a major step toward my long-held, earnest desire for nuclear weapons to be banned, and eliminated,” he said. Tritium is also produced in reactors by 10B(n, 2α)3H, 10B(n, α)7Li, 7Li(n, α)3H, or 6Li(n, α)3H, 2H(n, γ)3H5. It plans to draw up a report as early as next month. A series of wells were drilled at 35 m above sea level, upstream of FDNPP, to reduce the amount of groundwater flowing under the reactor building, and the well water was constantly pumped (Ground water bypass).
