UN says radiation is high outside Japan’s exclusion zone

Latin Daily Financial News: According to AP information, recent radiation readings outside the exclusion zone around Japan's nuclear disaster show radiation substantially higher than levels at which the U.N. nuclear agency would recommend evacuations, agency officials said Wednesday.

The comments could add to the debate over how far people need to stay away from Japan's Fukushima Dai-ichi nuclear complex, which was crippled in the country's March 11 earthquake and tsunami.
Elena Buglova, an official from the International Atomic Energy Agency (IAEA), said the reading was 2 megabecquerels per square meter at the village of Iitate, adding that ""as a ratio it was about two times higher"" than levels at which the agency recommends evacuations.
Iitate is about 25 miles (40 kilometers) from the Fukushima complex where emergency crews are battling to keep radioactivity from spreading. Japanese officials have told residents to evacuate within a 12-mile (20-kilometer) zone and to stay indoors within 18 miles (30 kilometers) of the damaged complex, but U.S. officials have recommended citizens stay at least 50 miles (80 kilometers) away.
The officials emphasized that the readings at the village of Iitate were sporadic and only at one measuring point. They did not say exactly when the readings were taken but mentioned them along with radiation measurements of iodine 131 and caesium 137 in soil samples between March 18 and March 26.
Denis Flory, a senior IAEA official, objected when asked whether the agency was recommending that the village be cleared of residents but said it had advised Japanese authorities to ""carefully assess the situation.""
""The highest values were found in a relatively small area in the northwest from the Fukushima power plant and the first assessment indicates that one of the IAEA operational criteria for evacuation is exceeded in Iitate village,"" he told reporters.
Buglova also indicated the readings were preliminary saying ""there is a range of uncertainty involved.""
Exceeding the evacuation limit does not necessarily mean the levels pose a serious health risk, as they are often extremely conservative and set well below where health damage can be expected.
