Japan has revealed radiation up to several hundred times normal levels has been detected on the seabed off the crippled Fukushima nuclear plant
The science ministry announced highly radioactive materials were detected in a 300km north-south stretch from Kesennuma in Miyagi Prefecture to Choshi in Chiba Prefecture, the Kyodo news agency reports.
The ministry warned that the contamination could affect the safety of seafood, the report said, without giving figures for the radiation levels detected.
The science ministry said it detected iodine and caesium on the seabed at 12 locations 15km to 50km from the coastline between May 9 and 14.The news followed an announcement by Greenpeace that marine life it had tested in waters more than 20km off the Fukushima nuclear plant showed radiation above legal limits.The anti-nuclear group, which conducted the coastal and offshore tests this month, criticised Japanese authorities for their “continued inadequate response to the Fukushima nuclear crisis'' sparked by the March 11 earthquake and tsunami.
Greenpeace said it detected seaweed radiation levels 50 times higher than official limits, which it charged raised “serious concerns about continued long-term risks to people and the environment from contaminated seawater''.It also said that tests, which it said were independently verified by French and Belgian laboratories, showed above-legal levels of radioactive iodine-131 and caesium-137 in several species of fish and shellfish.In the aftermath of the quake small amounts of radiation from Fukushima spread across Asia, deepening concerns for millions of people in countries which had already imposed bans on Japanese produce from near the nuclear plant.The governments of China, South Korea, the Philippines and Vietnam reported that radiation had drifted over their territories, although they emphasised the levels were so low that there was no health risk.Posted via http://batavia08.posterous.com batavia08's posterous
