Japan : TEPCO checks radiation levels in seabed near plant

Article from NHK News :

" Radiation levels 100 to 1,000 times above normal have been detected in the seabed near the damaged Fukushima Daiichi nuclear power plant.

The plant's operator, Tokyo Electric Power Company, conducted its first contamination analysis of the seabed near the plant using samples from 2 points 20 to 30 meters deep on Friday.

Samples collected about 15 kilometers north of the plant contained 1,400 becquerels of cesium-137 per kilogram and 1,300 becquerels of cesium-134.

Samples taken around 20 kilometers south of the plant contained 1,200 becquerels each of cesium-137 and cesium-134 per kilogram.

The samples from the 2 points were also found to be contaminated with iodine-131.

TEPCO says it's difficult to evaluate the readings as there are no official limits for these substances, but it will continue monitoring the radiation levels and their impact on seafood.

Another survey carried out by the science ministry on the same day detected no radioactive substances in samples from the seabed roughly 50 kilometers south of the plant."
