The accident was rated level 7 on the International Nuclear and Radiological Event Scale, due to high radioactive releases over days 4 to 6, eventually a total of some 940 PBq (I-131 eq). All four Fukushima Daiichi reactors were written off due to damage in the accident – 2719 MWe net.
What was the highest radiation reading at Fukushima?
The NRA's study found that the amount of radioactive cesium 137 was estimated at 20-40 petabecquerels between the space between the top and middle layers of the shied plug of the No. 2 reactor. That works out to more than 10 sieverts per hour based on readings of radiation levels nearby.
What is the current radiation level at Fukushima?
In November 2019 the Ministry of Economy, Trade and Industry stated that annual radiation levels from the release of the tritium-tainted water were estimated at between 0.052 and 0.62 microsieverts if it were disposed of at sea and 1.3 microsieverts if it were released into the atmosphere, compared with the 2100 …
Is Fukushima still leaking radiation 2021?
The radiation levels offshore of Fukushima have dropped in the years since, but some of the reactors there are still leaking. And over the last decade, TEPCO has continued to cool the fuel cores with water, which is contaminated by the process.
Is Fukushima more radioactive than Chernobyl?
According to the International Atomic Energy Agency (IAEA), there was less total atmospheric release of radioactivity from the Fukushima accident compared with Chernobyl due to the different accident scenarios and mechanisms of radioactive releases.
Why was Chernobyl worse than Fukushima?
Chernobyl had a higher death toll than Fukushima The toxic fumes not only contaminated the local vegetation and water supply near Pripyat (a Ukrainian city that was once part of the Soviet Union) but also poisoned nearby residents, some of whom went on to develop cancer.
What was the Roentgen level at Chernobyl?
The ionizing radiation levels in the worst-hit areas of the reactor building have been estimated to be 5.6 roentgens per second (R/s), equivalent to more than 20,000 roentgens per hour.
Is Fukushima still leaking 2022?
Japan's industry ministry and the IAEA have agreed to compile an interim report on the water discharge plan in 2022. Officials say it is now safe to live in most areas around the plant except for its immediate surroundings after extensive decontamination work.
How long will Fukushima be contaminated?
Past and Present contamination The half-life of radiocesium is about 29 years, meaning the quantity of the radioactive material should drop by half by roughly 2041. The leftover radiation from the much larger Chernobyl disaster of 1986 roughly follows that pattern, Johnson says.
Will Fukushima ever be habitable?
By Bruce Gellerman. A large area around the Fukushima nuclear power plant will be uninhabitable for at least 100 years.
