Tokyo:World Health Organisation Report

 World Health Organisation said on Monday that radiation in food after an earthquake damaged Japanese nuclear plant was more serious than previously thought, eclipsing signs of progress in a battle to avert a catastrophic meltdown in the reactors.
Engineers managed to rig power cables to all six reactors at the Fukushima complex, 240 km north of Tokyo, and started a water pump at one of them to reverse the overheating that has triggered the world’s worst nuclear crisis in 25 years.
Some workers were later evacuated from one of the most badly damaged reactors when gray smoke rose from the site. There was no immediate explanation for the smoke, but authorities had said earlier that pressure was building up at the No. 3 reactor.
The amount of smoke later receded and Japan’s nuclear safety agency said there was no significant change in radiation levels at the site.
The March 11 earthquake and tsunami left more than 21,000 people dead or missing and will cost an already beleaguered economy some $250 billion, making it the world’s costliest ever natural disaster.
However, he said there was no evidence of contaminated food from Fukushima reaching other countries.
Tap water
Japan’s health ministry has urged some residents near the plant to stop drinking tap water after high levels of radioactive iodine were detected.
Cases of contaminated vegetables and milk have already stoked anxiety despite assurances from officials that the levels are not dangerous. The government has prohibited the sale of raw milk from Fukushima prefecture and spinach from a nearby area.
There were no major reports of contaminated food in Tokyo, a city of about 13 million people. City officials however said higher-than-standard levels of iodine were found in an edible form of chrysanthemum.
Japan is a net importer of food, but has substantial exports – mainly fruit, vegetables, dairy products and seafood – with its biggest markets in Hong Kong, China and the United States.
The prospects of a nuclear power plant meltdown in the world’s third-biggest economy and its key position in global supply chains rattled investors worldwide last week and prompted rare joint currency intervention by the G7 group of rich nations to stabilise markets.
Tokyo’s markets were closed for a holiday on Monday. The Nikkei index shed 10 per cent last week, wiping $350 billion off market capitalisation, and at one point had lost as much as 20 per cent in value.
In a much-needed boost for the battered market, billionaire investor Warren Buffett said the earthquake and tsunami were an “enormous blow” but should not prompt the selling of Japanese shares. Instead, he called events a “buying opportunity”.
Situation critical at plant
At Fukushima, 300 engineers have worked around the clock inside an evacuation zone to contain the worst nuclear accident since Chernobyl, Ukraine, in 1986.
