Fukushima Power plant Level 7 - same rating that Chernobyl reached with one reactor

Japan's nuclear safety agency has raised the crisis level at the stricken Fukushima Daiichi nuclear power plant to 7, from the current 5.

The agency told reporters on Tuesday that large volumes of radioactive substances that could affect human health and the environment are being released in a wide area.

Level 7 is the highest rank on an international standard and equivalent to the severity recorded after the Chernobyl disaster in 1986.

But the agency said the volume of radiation from Fukushima is one-tenth that at Chernobyl.

The agency said its calculations show that 370-thousand terabecquerels of radioactive iodine 131 and cesium 137 have been released from the plant.

The nuclear safety commission, in a joint press conference with the agency, put the estimated leak at 630-thousand terabecquerels of both substances.

One terabecquerel is equivalent to one trillion becquerels. Both organizations say the leak constitutes a level-7 crisis.

Senior agency official Hidehiko Nishiyama said 29 people died of acute radiation exposure at Chernobyl but there are no fatal radiation casualties at Fukushima.

He added that at Chernobyl the nuclear reactor itself exploded in contrast to the Fukushima plant, which was damaged by hydrogen explosions. He said the reactors themselves retain their shape.

Nishiyama also said the upgrade does not affect the existing evacuation plan, which was made on the basis of the same radiation evaluation.

The agency is required to announce the severity of a crisis at a nuclear facility based on the international standard from zero up to 7 set by the International Nuclear Event Scale.

The president of the operator of the quake-damaged Fukushima Daiichi power plant says he is taking the decision by the government's nuclear safety agency seriously.

Masataka Shimizu, the head of Tokyo Electric Power Company, released the comment on Tuesday after the agency raised the crisis level of the accident to 7, the worst on the international scale of nuclear incidents.

He said he is deeply sorry for causing trouble and concern to nearby residents and people in Fukushima Prefecture, as well as to the public.

Shimizu said he wants to resolve the ongoing accident as soon as possible, adding that his company is trying to cool the crippled reactors down and prevent the dispersion of radioactivity.
He also said the company is considering various possible ways and steps to contain the nuclear crisis.

He added that his company will make all-out efforts to resolve the problem in close cooperation with the government, related ministries and municipalities.

Shouldn't the company have been making an all-out effort from Day 1, not a MONTH later?

Those poor Japanese people, what a dreadful tragedy. With their food supply being contaminated, their sea of contaminated fish. Dairy cows contaminated milk, this is really going to cause a shortage of food for them. There seems to be a shortage of food all across the globe. Even food prices in BC, have gone through the roof.

However, I am happy to know, Canadians donated funds to Japan. Even the BC people, who are struggling to get by, because of all of the terrible taxes, that have been inflicted upon us, we have also donated what ever we could spare. Every little bit of cash helps the Japanese people, to get through their terrible

We have to pray, they are able to, put a lid on those reactors, to cool them down. There could be severe problems, in other countries as well.

China too, is worried about their food supply becoming contaminated. There are millions upon millions of people, to feed in China. Acid rain, can do a lot of damage to food crops, animals feed and all.

The Japanese nuclear disaster is underpinned by several social determinates of health. A reported 250,000 people are currently homeless, food and water supplies are limited it seems inevitable that health standards will continue to be under pressure well into the future, even the most robust health system will struggle to cope in such circumstances. Early childhood development is proving to be essential in providing a solid framework to good health. Concern surrounds parents and pregnant woman in the regions surrounding the coastal power plant and the influence this tragedy has had on their access to clean drinking water, fresh and nutritious foods, adequate healthcare and social support. Fears regarding traditional food stables like fish and seaweed have been raised after high radioactivity has been detected in the ocean around the power plant.... They will need continued support from us all...
