In an attempt to cool down the reactors, the scientists that works at Fukushima filled each containment barrier with sea water and a mixture of boric acid. The Boric acid is often used as a flame retardant and a neutron absorber and is commonly found involved with nuclear reactors because of its high cross-section for neutron capture. It is often referred to as a neutron poison. The brown on the mixture decreases the chances of increased thermal fission because it sorbs some of the thermal neutrons. Fission chain reactions are often powered by the probability the free moving neutrons will result in fission. By adding boric acid to a coolant, the odds thats a neutron will cause additional fission is greatly reduced. Unfortunately, when …show more content…
And not only did the radiation affect farming and land, but it also had devastating effects on the ocean’s ecosystem. Because of the Fukushima nuclear meltdown, the Pacific Ocean experienced more discharge of radioactive waste than any other ocean in the world. The immediate effects were devastating for fishers. Around 56% of all of fisher’s catches had noticeable traces of cesium. Because of such drastic conditions, drastic measures were taken to ensure safety of Japanese citizens. Fishing was banned off some coasts of the countries for months before it became regulatory again. The possible threat of radiation poisoning was so great because many were afraid that it would lead to the regular indigestion of low levels of radiation which can be extremely harmful to the body’s internal organs, causing ionization to the body’s cells that lead to cancer. But in a article published in 2015 by Forbes, a writer specializing in nuclear energy made an argument that suggested that Fukushima wasn't disastrous because of the radiation, but because of the tsunami and earthquake. A report by the World Health Organization states that “the predicted risks are low and no observable increases in caner rates above baseline are
(Events of Fukushima Nuclear disaster) The Fukushima Nuclear disaster had many effects on the environment and health, some of its effects on the health are, infection of skin and that is mainly caused because of radiation and chemicals in the water after the incident and little supply of clean water, it also impacted the citizens physiologically (mainly the mothers, kids and workers) who might have diseases as anxiety and depression, problems in pregnancy, related to deficiency of iodine in the body, and some hormones not functioning properly, all these causes might lead to still birth, and miscarriage and finally, radiation syndrome which is caused because of the release of massive amounts of radiation, spread of cancer (as thyroid cancer) because of radiation, and ascend of genetic inheritable diseases As in Diagram 2 (Health Concerns in Fukushima), we can signify that the percentages of cancer increased highly because of the disaster in comparison to nowadays and especially between people of ages (1month-20years)
Recently, the deserted Fukushima Daiichi Nuclear Power Plant has been emanating an alarming amount of radiation. Kyodo of Japan Times reported that the radiation reading has reached its highest level since its emergence in March 2011 (Kyodo, 2017). As a result, there is a greater presence of air and water pollution in Fukushima that could easily spread to surrounding areas. Therefore, it seems appropriate that in an interview with the Washington Post, radio-ecology expert Tom Hinton stated Fukushima is “an area that is among the most radioactively contaminated in the world” (as cited in Andrews, 2016). This resurgence has generated conspiracy theories, false maps and, interestingly, little news coverage. While many across different continents
The oceanic pollution that resulted from the discharge of radioactive materials following the accident at the Fukushima Daiichi Nuclear Power Station was a concern not only for the coastal population of Fukushima, but also for countries facing the Pacific Ocean. This called for rapid clarification of the actual dispersal situation by oceanic monitoring, but there were limits to collect water samples by ships, and it was difficult to gain an adequate understanding.
The most egregious facet of the ongoing fiasco that is the Fukushima Daiichi nuclear incident is widely accepted to be the intentional release of hundreds of tons of radioactive water into the oceans surrounding the reactors. In terms of total radioactivity released into the environment, Fukushima has already surpassed the Chernobyl incident of the 1980s, that Soviet-sized lead balloon (plutonium balloon?), which is the only other Level 7 event on the International Nuclear Event Scale. But another seemingly forgotten relic of the Cold War could pose an even greater nuclear threat to our oceans, although it has yet to receive the same level of scientific and political scrutiny as these two accidental events.
According to the researchers 70% of all backup generators were washed away by the tsunami, so being unable to cool itself, Fukushima’s reactors melted down. According to Synolakis, when the power plant was built, they set generators in the basement only 12 meters above
Then the question came up that how did the natural disaster occurred, man-made hazards with high technology, and heighten the risk to environmental health. Acceding to the Implications of the Fukushima Nuclear Disaster: Man-Made Hazards, Vulnerability Factors, and Risk to Environmental Health, first of all, the earthquake and tsunami exceeded estimations. Many international sources suggested that secondary technological is needed in order to estimate that incident. This Fukushima incident involved the first ever reactor core melt occurred by earthquake and tsunami. Since Fukushima is north part of japan by the ocean, many fish market and dealer were there, however, people started buying from them because of radiation. Radiation makes affect not only human. It is also effect environment and natural animals such as fishes. If you eat affected fish you will also get effect of radiation. The Fukushima disaster became a public debate emerge over the future desirability of nuclear power in Japan. Despite the growing anti-nuclear sentiment and concerns about the environmental risks of nuclear power, we contend that the continuing power of vested
In 2011, a tragic calamity has shocked the entire world. The radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant were released due to the consequent tsunami caused by the the 2011 Tōhoku earthquake. Massive amount of radioactive sewage flowed into Pacific Ocean and Japanese sea. Substantial number of dangerous substances were transmitted through air. The radioactive substances not only devastated the environment, but also severely jeopardized the health of all the creatures ranging from Japan to North America. Uncountable innocent marine animals mutated and died, which led to
On March 11, 2011, Japan was hit by an earthquake and a tsunami resulting in 15,894 confirmed deaths, with 2,556 people missing. This was the fourth strongest earthquake to hit in recent years with a magnitude of 9.1 (“Damage Station Police” ). However, this was not the only disaster to have struck Japan, the combination of the earthquake and tsunami led to the meltdown of a power plant in, Tōhoku region, Japan. This event became known as the Fukushima Daiichi nuclear disaster. Nuclear meltdowns has contributed harm to many environments by radioactive leaks, soil contamination, and radiation exposure.
There was a massive earthquake on March 11th, 2011 which led to an explosion at the Fukushima Daichi Nuclear Power Plant(NPP) which resulted in the release of huge amounts of harmful radioactive materials from the NPP into the environment. These radioactive substances further spread to the farms and also contaminating aquatic life, therefore, affecting the whole ecosystem overall. It was further reported by the Japanese Government that the concentration of radioactive substance cesium found in some freshwater fish in Fukushima Prefecture has still not recovered to safe limits i.e. 100 Bq/kg of radiations as they were exposed to the radiations as soon as the accident occurred, but the concentration of cesium in marine fish was found comparatively
Fukushima was the second worst nuclear disaster in the history of the world. TEPCO reported that 300 tons of contaminated water had leaked from a storage tank into the ocean. Cod and pollock are important because of their global demand. Japanese cod has tested positive for radiation contamination a number of times since the Fukushima disaster, not only in the Fukushima area, but in many other areas too. 70% of domestic product comes from the Pacific Ocean. This has led to a lot of negative information circulating through Japanese society and a shortage of positive information (or at least an indifference to it. Negative information is known to have a stronger impact on consumers than positive. Very few people are aware of the Japanese government’s
Also, the Pacific Marine life has been Severely Affected. Regarding Japan nuclear reactors after the accident, in 2011 31 of Japan’s 50 nuclear power plant reactors were shut down and only 19 were operating which make the power supply in japan become severely constrained. Fukushima accident has harmed Japan in not only in the nuclear field but also in many other fields such as agriculture, forestry, and fisheries; manufacturing; education; industry; tourism; politics. Finally, Tepco has struggled to handle the complex task of cleaning up the accident mess. To prevent further contamination, TEPCO had constructed a frozen soil barrier, but in 2016 they revealed that "the ice wall had failed to stop groundwater from flowing in and mixing with highly radioactive water inside the wrecked reactor buildings, adding that they are technically incapable of blocking off groundwater with the frozen wall”. (Biggs & Humber, 2011; Collins). Critics have blamed the government for leaving the plant in the hands of the same operator who failed to avoid the accident in the first
The impact from the accident at the nuclear power plant in Fukushima, Japan has had major biological effects that are still effecting people, animals and plants to this day.
TEPCO not only released the total of 11,500 tons of waste water, but also used seawater to cool down the damaged reactors.The release of this highly contaminated water led to radioactive discharges directly into the sea. Those actions done by TEPCO lead the whole East Japan's marine ecological catastrophe and seafood pollution and cannot eat or
More than a year after the earthquake/tsunami destroyed the Fukushima Daiichi Nuclear Power Plant in Japan, a large amount of fish in the area contain a significant amount of radioactive cesium that as high as they were when soon after the disaster happened, meaning that this problem is not going to go away any time soon. Scientists believe that it could take years, even decades to restore the ocean and its inhabitants to a safe amount of radiation. The levels of radiation are reaching the US west coast. Due to the reactors still leaking and spewing radiation many think this has caused the death in the Pacific of thousands of baby sea lions on the California coast, and 500 navy soldiers are still suffering from radiation poisoning after responding to the earlier Fukushima disaster. We also have reports that West Coast orca whales are experiencing extremely high infant mortality rates as radiation from Fukushima drifts across the ocean. The high level of radiation has now reached other countries through the ocean and it is affecting everything in its
On March 11th, 2011, the northern section of Japan was hit by a 9.0 magnitude earthquake, followed by a 15 meter tsunami, causing the death of over 15000 people. (Spacey) Even though the earthquake and the tsunami caused a tremendous amount of deaths in the northern region of Japan, the meltdown of the Fukushima nuclear power plant caused a severe damage to northern Japan’s ecosystem that people still cannot go back to their homes; despite it is 4 years after the disaster. After the earthquake, the tsunami destroyed the power supply used by Fukushima’s three nuclear power stations, causing severe levels of meltdown to be occurred inside the reactors in the timespan of 3 days. It was not until 2 weeks after the tragedy, when the reactors were finally stabilized, and took several months to approach what is called a “cold shutdown condition”, in which the fission in the reactors are completely stopped.(Fukushima A)
