Spinach with radioactive iodine 27 times more than the government-regulated limit was found in the city of Hitachi in Ibaraki Prefecture, more than 100 kilometers south of the crippled Fukushima Daiichi nuclear power plant, but the radiation levels do not affect human health, local authorities said Sunday. The growing public concern over the safety of farm products prompted the government the same day to consider instructing local authorities to halt the shipment of relevant produce within a prefecture if produce made there is found containing radioactive substances at levels exceeding regulation, government sources said. Currently, prefectural governments decide whether to ask municipalities to voluntarily halt shipment of contaminated products. In 1 kilogram of spinach grown in open air in the city, 54,000 becquerels of iodine was detected, exceeding the 2,000 becquerel limit preliminarily set by the government under the food sanitation law, the Ibaraki prefectural government said. The level of cesium in the spinach grown in the city was also higher at 1,931 becquerels, compared to the limit of 500 becquerels.

"The total area contaminated with radiation from the Fukushima No. 1 nuclear power plant is estimated at about 800 square kilometers, or about 40 percent the size of Tokyo, according to a radiation map created by the science ministry and U.S. Department of Energy. The report uses the same level of contamination (555,000 becquerels or higher of cesium-137) that was used to issue compulsory evacuation orders in the Chernobyl nuclear accident in 1986. To determine whether the current evacuation zone is appropriate or when residents can return home, the Nuclear Safety Commission of Japan plans to set up focal sites to heighten its monitoring of the possible further spread of radioactive contamination.

"A group of Japanese researchers say that a total of 15,000 terabecquerels of radioactive substances is estimated to have been released from the crippled Fukushima Daiichi nuclear power plant into the sea. Researchers at the Japan Atomic Energy Agency, Kyoto University and other institutes made the calculation of radioactivity released from late March through April. The combined amount of iodine-131 and cesium-137 is more than triple the figure of 4,720 terabecquerels earlier estimated by Tokyo Electric Power Company, the plant operator. The utility only calculated the radioactivity from substances released from the plant into the sea in April and May. The researchers say the estimated amount of radioactivity includes a large amount that was first released into the air but entered the sea after coming down in the rain. They say they need to determine the total amount of radioactivity released from the crippled Fukushima Daiichi plant in order to accurately assess the impact of the disaster on the sea."

-With no end in sight to the crisis at the Fukushima Daiichi nuclear power plant, Japan's neighbors are increasingly stepping up efforts to curb food imports, both fresh and processed, from parts of Japan. South Korea has temporarily banned vegetables from Fukushima and four other prefectures. In addition, the Seoul government on Thursday announced a new measure that calls for government-issued documents for all food products -- mostly processed foods -- from Tokyo, Miyagi and six other prefectures certifying safe levels of radioactive iodine and cesium. The new requirement takes effect May 1. South Korea is also requesting that products from 34 other prefectures be accompanied by documents identifying their origin. As the Japanese have yet to decide whether to accede to the request, importation of such familiar Japanese products as sake rice wine, snacks and cooking sauces, is expected, in effect, to come to a halt starting next week. Another neighbor, Taiwan, has also prohibited food imports from five prefectures, including Fukushima. In addition, all fresh produce and some processed foods from Japan must be tested for radioactivity when they arrive.

The accumulated radiation level in Namie, 30 kilometers from the crippled Fukushima Daiichi nuclear power plant, in the three weeks through Friday stood at 17,010 microsieverts, according to a tally released by the science ministry Saturday. The accumulated levels during the period starting March 23 stood at 9,850 microsieverts in Iitate and 495 microsieverts in Minamisoma, both near the plant, it said. The readings compare with the level of 1,000 microsieverts that ordinary people in Japan can expect to be exposed to over one year. The amount of radioactive cesium stood between 12.7 and 71.0 becquerels per liter of surface seawater near the plant on Monday and Wednesday and 10.1 becquerels at deeper levels on Monday, the Ministry of Education, Culture, Sports, Science and Technology said.

"Radiation is expected to continue spewing for months from Japan's Fukushima Daiichi nuclear power plant that suffered a meltdown following an earthquake and tsunami in March, but despite grim reports from Japan, the US Environmental Protection Agency (EPA) has quietly stopped running extra tests for radioactive material in America's milk, rain and drinking water. The EPA initially ramped up nationwide testing in the weeks following the disaster in Japan, and radioactive materials like cesium and iodine-131 were detected on US soil. Citing declining levels of radiation, the EPA has abandoned the extra tests, even as reports from Japan indicate that the Fukushima plant continues to emit radiation and the disaster is one of the worst in world history."

"Revelations that radiation-contaminated rice straw used as feed for beef cattle was produced far away from the crippled Fukushima No. 1 Nuclear Power Plant have sent shockwaves through the livestock farming community in Fukushima Prefecture. Consumers have also been filled with a sense of growing distrust in the government over delays in responding to the problem of radiation-tainted beef. Forty-two beef cows that ate rice straw contaminated with radioactive cesium were found to have been shipped from a livestock farm in the Fukushima Prefecture town of Asakawa from April 8. The rice straw had been supplied by a farmer in Shirakawa, about 75 kilometers away from the tsunami-hit nuclear power station."

An Italian court has ordered the recall of 10,000 tonnes of wood fuel pellets imported from Lithuania over fears that they could have dangerous levels of radioactivity, newspapers reported on Sunday. The alarm was raised after someone in the northern Aosta Valley region, who had bought the pellets, sent them for analysis because they did not burn well. The results showed that they contained caesium 137, a highly toxic radioactive substance normally produced by a nuclear explosion or from the combustion of a nuclear reactor. The contaminated pellets themselves are not dangerous to humans, said Salvatore Aprile of the Aosta Valley court: the dangers comes from the ashes and the smoke produced when they are burned. The court ordered their recall on Saturday. The pellets at the centre of the alert were imported from Lithuania last autumn and were sold in 11 regions in the north and south of Italy.

Chinese officials say that potentially deadly radioactive material lost in north-western Shaanxi province may have been found at a steel mill. Officials told the BBC that they had detected what may be the missing Caesium-137, adding that it may have been melted down. The Caesium-137, encased in lead, was lost this week when workers at a cement plant demolished an old factory. The material was part of a measuring instrument and is extremely dangerous.
