Anybody with and an up-to-date map of this especially after the Fukushima disaster?
You could see the recent Book "Recent trends in modeling of Environmental Contaminants" published by Springer in July 2014. Also see the recent publications by Prof. Katsumi Hiroshe. I presume that it would provide all what is needed.
Hi Billy,
I think that dispersion of radionuclides in the ocean (Japanese East coast south of Fukushima) got quite a dose of radionuclides from Fukushima radioactive water releases as well (uncontrolled, as well as controlled, and from radioactive soil water leakage into the ocean as well).
I made a rough estimation of this type of dispersion south from Fukushima, based in drinking water plants (desalinisation plants) along the Eastcoast. One plant 500 km South from Tokyo received high radioactive material on its intake grid months ago. Normally, the solid materials collected on the intake grid are used as fertiliser on agricultural land. The drinking water company stopped this practice after measurements of the radioactivity of the solids collected on the intake grid of the drinking water plant. These solids are now stored as nuclear waste, till a solution has been found to process it.
This means, that about 700 to 800 km of coastal waters and shores South from Fukushima are contaminated with radionuclides. This includes the waters at Tokyo about 200 km south from Fukushima.
I did not find any data or measurements of coastal sessile organisms (consumed in Japan), which could or do confirm my very rough assessment of radioactive contamination along the Japanese Eastcoast. Anyhow, I would be carefull eating sushi, especially sushi based on seafruits and/or seaweeds. It may sound like a joke, but remember the Minamata catastrophy? What about Plutonium instead of Mercury, and 800 km of coastline instead of one bay (Minamata bay area)?
Cheers,
Frank
