Japan urged to extend nuclear exclusion zone - Aljazeera.net

The UN nuclear watchdog has suggested Japan consider widening an evacuation zone around a tsunami-damaged nuclear plant as radiation continues to leak into seawater near the plant.

The International Atomic Energy Agency (IAEA) said on Thursday radiation measured at the village of Iitate, 40km from the crippled Fukushima Daiichi nuclear plant, exceeded a criterion for evacuation.

Radioactivity in the seawater has reached more than 4,000 times its legal limit, the Reuters news agency reported.

"We have advised (Japan) to carefully assess the situation and they have indicated that it is already under assessment," Denis Flory, the IAEA's deputy director general, said.

Concerns over radiation spreading beyond Japan grew again after Singapore detected radiation nine times the limit in cabbages imported from Japan while the United States reported small levels of radiation in milk samples on its west coast.

Japan has ordered those within a 20km radius from the plant to leave and is encouraging those living in a 20-30km ring to do the same, and if they do not, to stay inside.

Tens of thousands of people, including farmers and their families have been evacuated from the exclusion zone around the plant.

Another 130,000 who live in a 10km band beyond the exclusion zone have been advised either to leave or stay indoors.

There is no indication how long they will be homeless.
TEPCO, the company that runs the plant, said it was inevitable it would have to scrap four of its six reactors at the plant. Scrapping the damaged nuclear reactors may take decades, said Japan's Nuclear and Industry Safety Agency.

Prime minister criticised

The IAEA's suggestion came as the opposition criticised Naoto Kan, the prime minister, for failing to expand the evacuation zone.

Greenpeace this week said it had confirmed radiation levels in Iitate village high enough to evacuate, but Japan's nuclear safety agency has rebuffed the environmental group's call.

Meanwhile Nicolas Sarkozy, president of nuclear-dependent France, was due to arrive in Japan on Thursday, the first leader to visit since a devastating earthquake that was followed by a tsunami sparked the world's worst nuclear crisis since Chernobyl in 1986.

Sarkozy, who chairs the G20 and G8 blocs of nations, was due to meet Kan to show support for Japan's efforts to end its nuclear crisis.

France has flown in experts from its state-owned nuclear reactor maker Areva CEPFi.PA, while the United States has offered robots to help repair the crippled plant north of Tokyo.

Further assistance is expected as the US military on Wednesday ordered a Marine unit specialising in emergency nuclear response to deploy to Japan and assist local authorities in addressing the massive crisis, officials said.

Some 155 Marines from the service's Chemical Biological Incident Response Force are scheduled to leave the United States on Thursday and arrive in Japan on Friday, a US defence official told the AFP news agency.

The CBIRF team, trained in identifying chemical agents, monitoring radiation levels and decontaminating personnel, would not participate in the frenzied efforts to stabilise the reactors of the nuclear plant.

The nuclear plant was also hit by several explosions, triggering fears of a catastrophic meltdown as radiation has wafted into the air and seeped into the ocean.

US military personnel are currently barred from penetrating an 80km radius around the stricken plant, far exceeding the 20km exclusion zone imposed by the Japanese government.

Japan is also facing a humanitarian calamity triggered by the earthquake and tsunami, which has left more than 27,500 people dead or missing.

Experts warn that tsunami survivors mourning lost loved ones and struggling to replace shattered homes and workplaces also face daunting mental health concerns.
