Radiation scare sparks run on bottled water in Tokyo



Thu Mar 24, 2011 6:09am GMT
* Contamination fears spread in Japan and beyond
* Disaster damage estimated at $300 billion
* U.S., Hong Kong, Australia, Singapore restrict food imports
* Engineers battle to stabilise Fukushima reactors

TOKYO, March 24 (Reuters) - Stores in Tokyo were running out of bottled water on Thursday after radiation from a damaged nuclear complex briefly made tap water unsafe for babies, while
more nations curbed imports of Japanese food.

Engineers are trying to stabilise a six-reactor nuclear plant in Fukushima, 250 km (150 miles) north of the capital, nearly two weeks after an earthquake and tsunami battered the plant and devastated northeast Japan, leaving nearly 26,000 people dead or missing.

Tokyo's 13 million residents were told not to give tap water to babies under 1 year old after contamination hit twice the safety level this week. But it dropped back to allowable amounts
on Thursday.

Despite government appeals against panic, supermarkets and stores sold out of bottled water.

"Customers ask us for water. But there's nothing we can do," said Masayoshi Kasahara, a store clerk at a supermarket in a residential area of eastern Tokyo. "We are asking for more
deliveries but we don't know when the next shipment will come." Radiation above safety levels has also been found in milk and vegetables from Fukushima, where the stricken nuclear plant is located on the Pacific coast.

Singapore and Australia joined the United States and Hong Kong in restricting food and milk imports from the zone, while Canada became the latest of many nations to tighten screening
after the world's worst atomic crisis since Chernobyl.

Radiation particles have been found as far away as Iceland, although Japan insists levels are not dangerous to adults.

The contamination scare after the catastrophe of March 11 is adding to Japan's most testing time since World War Two.

The estimated $300 billion damage from the 9.0 magnitude earthquake and ensuing tsunami makes it the world's costliest natural disaster, dwarfing Japan's 1995 Kobe quake and Hurricane
Katrina, which swept through New Orleans in 2005.

In Japan's devastated north more than a quarter of a million people are in shelters. Some elderly refugees, among an ageing population, have died from cold and lack of medicines.

Exhausted and traumatised rescuers are still sifting through the mud and wreckage where towns and villages once stood.

The official death toll from the disaster has risen to 9,523, but is bound to rise as 16,094 people are still missing.

Amid the suffering, though, there was a sense that Japan was turning the corner in its humanitarian crisis. Aid flowed to refugees, and phone, electricity, postal and bank services began returning to the north, sometimes by makeshift means.

"Things are getting much better," said 57-year-old Tsutomu Hirayama, staying with his family at an evacuation centre in Ofunato. "For the first two or three days, we had only one rice ball and water for each meal. I thought, how long is this going to go on? Now we get lots of food, it's almost like luxury."

In other cheering news, a baby dolphin was rescued in a rice field after the tsunami dumped it there. Locals wrapped it in wet towels before taking it back to the sea.

Aftershocks are still coming, though, sending shudders through many Japanese. Several shook Tokyo on Thursday.

Admiration for Nuclear Workers

At the Fukushima plant, where the worst nuclear drama is playing out since Chernobyl in 1986, technicians have successfully attached power cables to all six reactors and started a pump at one to cool overheating fuel rods.

Nearly 300 engineers, fast becoming national heroes for braving danger inside an evacuation zone, are fighting to cool fuel rods at the plant's reactors.

They resumed work on Thursday at the No.3 reactor, considered the most critical, after a one-day suspension when black smoke was seen rising, Kyodo news agency said. Operator Tokyo Electric Power Co (TEPCO) is trying to re-start systems to keep the fuel cool and prevent further radiation leaks or a complete meltdown, the nightmare scenario.

Japan urged the world not to overreact to the radiation precautions, and plenty of experts appeared to back that up.

Jim Smith, of Britain's University of Portsmouth, said the finding of 210 becquerels of radioactive iodine, twice the safety limit, at a Tokyo water purification plant on Wednesday
should not be cause for panic. The safety level for adults is 300 becquerels.

"The recommendation that infants are not given tap water is a sensible precaution. But it should be emphasised that the limit is set at a low level to ensure that consumption at that level is safe over a fairly long period of time," he said.

"This means that consumption of small amounts of tap water -- a few litres, say -- at twice the recommended limit would not present a significant health risk."

Tokyo metropolitan government said it would access extra bottled water from stockpiles but could not say for how long.

Philippine Airlines said it was airlifting a donation of 27 tonnes, or 70,000 bottles, of water. The cargo is the first batch of a total 700,000 bottles of 350 ml each donated by sister company Asia Brewery Inc.

The crisis in the world's third-biggest economy -- and its key position in global supply chains, especially for the automobile and technology sectors -- has added to jitters in global financial markets, also worried by conflict in Libya and Middle East protests.

Toyota Motor Corp , which has suspended production at all of its 12 assembly plants in Japan, said it would slow some North American production because of supply problems although it would try to minimize disruptions.

WHO warns of "serious" food radiation in disaster-hit Japan


Mon Mar 21, 2011 10:08am GMT

* Radiation in food a "lot more serious" than first thought - WHO
* Power cables hooked up to all 6 reactors at crippled Fukushima plant
* Workers evacuated as smoke rises from badly damaged reactor
* U.S. energy secretary says worst of nuclear crisis may be over

By Junko Fujita and Kazunori Takada

TOKYO, March 21 (Reuters) - The World Health Organisation said on Monday that radiation in food after an earthquake damaged a 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 (150 miles) 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.

News of progress at the nuclear plant was overshadowed by mounting concern that radioactive particles already released into the atmosphere have contaminated food and water supplies.

"Quite clearly it's a serious situation," Peter Cordingley, Manila-based spokesman for the World Health Organisation's (WHO) regional office for the Western Pacific, told Reuters in a telephone interview.

"It's a lot more serious than anybody thought in the early days when we thought that this kind of problem can be limited to 20 to 30 kilometres ... It's safe to suppose that some contaminated produce got out of the contamination zone."

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.

"From reports I have heard so far, it seems that the levels of radioactive iodine and caesium in milk and some foodstuffs are significantly higher than government limits," said Jim Smith, a specialist in earth and environmental sciences at Britain's Portsmouth University.

"This doesn't mean that consumption of these products is necessarily an immediate threat, as limits are set so that foodstuffs can be safely consumed over a fairly long period of time. Nevertheless, for foodstuffs which are found to be above limits, bans on sale and consumption will have to be put in place in the affected areas."

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.

China would monitor food imported from Japan, the Xinhua news agency said, citing the country's quality control watchdog. South Korea said it would expand inspections for radioactivity to processed and dried agricultural Japanese food, from just fresh produce.

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.

Moody's Investors Service said in a report that the downside risks from the crisis had increased over the past week for the economy, sovereign credit, banking, insurance and non-financial corporate sectors.

Tokyo's markets were closed for a holiday on Monday. The Nikkei index shed 10 percent last week, wiping $350 billion off market capitalisation, and at one point had lost as much as 20 percent 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".

"It will take some time to rebuild. But it will not change the economic future of Japan. If I owned Japanese stocks, I would certainly not be selling them," Buffett said during a visit to a South Korean factory run by a company that is owned by one of his funds.

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.

They have been spraying the coastal complex with thousands of tonnes of sea water so fuel rods will not overheat and emit more radiation. Hopes for a more permanent solution depend on electricity cables reactivating on-site water pumps at each of the six reactors.

The most badly damaged reactors are No. 3 and 4, which were both hit by explosions last week.

U.S. Energy Secretary Steven Chu , asked by CNN whether the worst of Japan's 10-day nuclear crisis was over, said on Sunday: "Well, we believe so, but I don't want to make a blanket statement."

U.S. Nuclear Regulatory Commission Chairman Gregory Jaczko added that radiation levels at the plant appeared to be falling.

Prime Minister Naoto Kan also said the situation at the nuclear plant was slowly improving.

If the cooling pumps cannot restart, drastic measures may be needed like burying the plant in sand and concrete.

Official tolls of dead and missing are rising steadily -- to 8,450 and 12,931 respectively.

The death toll could jump dramatically since police said they believed more than 15,000 people had been killed in Miyagi prefecture, one of four that took the brunt of the tsunami.

The 9.0-magnitude quake and ensuing 10-metre (32-ft) tsunami made more than 350,000 people homeless. Food, water, medicine and fuel are short in some parts, and near-freezing temperatures during Japan's winter are not helping.
