A retired nuclear scientist gives his take on the events in Japan and the possible dangers to Americans.:
“One possibly worrisome long-term scenario is that the Fukushima-I plant is RIGHT on the Japanese east coast. I wondered about ocean currents and where they might deliver any radiation entering the ocean, AND what uptake and concentration mechanisms might be operable in sea-life in the various ocean ecosystems.
“The contaminants move through the ocean’s various food-chains, ultimately to species humans eat, potentially accumulating near the top of the food chains.
“Here on the U.S. coast we have become attuned to food-chain concentration of mercury in aquatic and other life, although I have no knowledge of the environmental pathways. Are we facing the possibility of a similar problem with some radioactive and heavy element species one, two, or three decades hence? Could my children’s salmon contain Japanese reactor fission products?”
