Applied to Japanese officials about food contamination spread beyond the borders of the country on Tuesday that the evidence of radiation in seawater from the coast.
Operator Tokyo Electric Power Co. announced that a large radioactive material found in sea water used in the vicinity, but said that the results do not represent a threat to human health.
“There should be no immediate health impact. If this situation continues for a long period of time, some impact can occur,” Chief Cabinet Secretary Yukio Edano told reporters.
The impact such radiation could have on marine life was unclear. Japanese authorities were scheduled to measure radioactivity in waters around the plant on Tuesday and Wednesday, the International Atomic Energy Agency said.
At the beginning of the level of radiation monitoring of sea water are iodine-131, which was 126.7 times higher than the state sets standards for the electricity company said on its website. It monitors detected cesium-134, which has a half-life of about two years, about 24.8 times higher than state standards. Cesium-137 was 16.5 times higher than standard.
The power company found these levels in sea water to 100 meters (328 feet) south of the nuclear plant Monday afternoon. Radioactive particles dispersed in the sea, and farther from shore, a sample is taken, the pollution should be less concentrated.
As the enormous dilution that takes place in the sea, there is a lot of opportunities for deep-sea fish are tainted, “said Murray McBride, a professor at Cornell University studying the contamination of soil and water.
“I think the ocean can handle that a lot better than the physical environment and population centers,” said Jim Walsh, an international security expert at the Massachusetts Institute of Technology and a CNN consultant. “We don’t want any of this to happen, but better it go out to sea than stay in Japan.”
The winds have blown a lot of radioactive materials by sea from the plant in an earthquake and the tsunami stopped cooling systems at the plant March 11.
But tests have detected the contamination of food grown near the plant.
The Japanese government has banned the sale of raw milk from Fukushima prefecture, where the factory, and prohibits the sale of spinach neighboring Ibaraki Prefecture, after finding levels of radioactive iodine and cesium higher levels of government, Ministry of Health reported the country.
Fukushima and officials halted the distribution of locally grown vegetables outside the prefecture.
The government also banned the sale of spinach and milk in areas of Gunma and Tochigi, according to the Office of the Prime Minister.
Tuesday Edan this contamination was not detected in other agricultural products.
“The products which are being grown in these areas are being monitored and the monitoring will continue,” he said.
He urged consumers to “try not to panic,” noting that the government had stopped shipments of any farm products they believed could be contaminated.
Edan said officials estimate that the radiation levels in food – while above the legal standards – does not pose an immediate health risk, saying they were of the most dangerous unless it is consumed several times during life.
On Monday, a spokesman for the World Health Organization said the short-term exposure to foods contaminated by radiation from Japan Fukushima Daiichi nuclear power plant damaged poses no immediate risk to health.
The tests also detected radiation in the water.
Monday, ‘he urged the authorities residing in the village of Iitake avoid drinking tap water that tests showed there were more than three times higher than the standard of life of radioactive iodine.
The water in other countries showed minor signs of contamination, but well below the level of concern under Japanese law, as the site of the International Atomic Energy Agency’s. UN agency said it had received reports from the Japanese government that six of 46 samples tested positive for iodine-131 radioactive isotopes.
Iodine and cesium isotopes are byproducts of nuclear fission reactors, such as those damaged March 11 earthquake and tsunami devastated the north of Honshu, the main island of Japan. Although iodine-131 is a radioactive half-life of eight days, cesium-137 half-life of approximately 30 years.
The decision to prohibit produce sales is another potentially devastating blow to a part of northeast Japan hit by the earthquake, tsunami and other potential fallout from the Fukushima plant.
Edano has said farmers will be compensated for revenue lost by the restrictions.
“Primarily this is due to the nuclear reactor accident, so we assume (Tokyo Electric Power Company) will be held responsible for compensation. The government might take some supplementary action,” he said.
Fukushima ranks among Japan’s top producer of fruits, vegetables and rice. Ibaraki, south of Fukushima, supplies Tokyo with a significant amount of fruits and vegetables and is Japan’s third-largest pork producer.
For radiation to be an issue for rice, the contamination would have to be more severe and prolonged that what has been seen so far, said McBride, the Cornell University professor.
Soil contamination was a huge issue around Chernobyl, but the radiation emitted from the Fukushima Daiichi plant isn’t anywhere near that level, he said.
“We’re not at that stage; that’s the scenario you have to consider if contamination gets severe enough,” McBride said.
