Radioactive contamination of the Pacific ocean spreads
"The Ministry of Education and Science disclosed on May 27 that radioactive materials in concentration that was up to several hundreds of times the normal level were detected from the soil on the ocean floor in the 300-kilometer strip along the coast from Kesennuma City in Miyagi Prefecture to Choshi City in Chiba Prefecture. The Ministry says "the marine products may be affected". It is now confirmed that the radioactive materials in the contaminated water released [both intentionally and unintentionally] from TEPCO's Fukushima I Nuclear Power Plant into the ocean have spread far and wide."
"The soil samples were taken from May 9 to May 14 at 12 locations about 15 to 50 kilometers off the coast. Radioactive materials were detected in all samples. The highest concentration of radioactive materials was detected from the sample taken from the ocean floor, 126 meters deep, 30 kilometers off the coast of Fukushima I Nuke Plant. Cesium-134 was 260 becquerels/kilogram, and cesium-137 was 320 becquerels/kilogram.
In comparison, in the survey done in 2009 in the approximately the same location, cesium-134 was not detected, and cesium-137 was 1 becquerel/kilogram.
Iodine-131, whose half life is short and was not detected at all in the 2009 survey, was found at 1.6 to 6.1 becquerels/kilogram."
