Japan: 8% of Country’s Surface Area Contaminated with Radioactive Fallout from Fukushima Disaster
November 22nd, 2011Via: ABC:
Japan’s science ministry says 8 per cent of the country’s surface area has been contaminated by radiation from the crippled Fukushima nuclear plant.
It says more than 30,000 square kilometres of the country has been blanketed by radioactive caesium.
The ministry says most of the contamination was caused by four large plumes of radiation spewed out by the Fukushima nuclear plant in the first two weeks after meltdowns.
The government says some of the radioactive material fell with rain and snow, leaving the affected areas with accumulations of more than 10,000 becquerels of caesium per square metre.
Last week tests found unsafe levels of radioactive contamination in recently harvested rice from the Fukushima region.
The levels of radioactive caesium were measured at 630 becquerels per kilogram, above the maximum allowable level of 500 becquerels.
Officials from Fukushima prefecture have now asked all rice farmers in the district to suspend shipments.

appears that Cs137 deposition on surface of 10K Bq/m2 is the arbitrary standard set defining “contamination”.
