Fukushima Reactor Disaster Being Ranked Now As a Potential Chernobyl Level Catastrophe

Here's the latest on raising the danger level to 7:

TOKYO – Japan raised the severity level of the crisis at its crippled nuclear plant Tuesday to rank it on par with the 1986 Chernobyl disaster, citing cumulative radiation leaks contaminating the air, tap water, vegetables and seawater.

Japanese nuclear regulators said the rating was being raised from 5 to 7 — the highest level on an international scale overseen by the International Atomic Energy Agency — after new assessments of radiation leaks from the Fukushima Dai-ichi plant since it was disabled by the March 11 tsunami.

The new ranking signifies a "major accident" with "wider consequences" than the previous level, including widespread health effects, according to the Vienna-based IAEA.

However, Japanese officials have played down any health effects of radioactive releases so far from the Fukushima plant. They said the leaks amount to only a tenth of the radiation emitted in the Chernobyl disaster, while acknowledging they eventually could exceed Chernobyl's emissions if the crisis continues.

"This reconfirms that this is an extremely major disaster. We are very sorry to the public, people living near the nuclear complex and the international community for causing such a serious accident," said Chief Cabinet Secretary Yuki Edano.

But Edano told reporters that there was so far no "direct health damage" from the crisis. "The accident itself is really serious, but we have set our priority so as not to cause health damage."
The revision came a day after the government added five communities to a list of places people should leave to avoid long-term radiation exposure. A 12-mile (20-kilometer) radius already had been cleared around the plant.
