Thousands evacuate as Fukishima nuclear emergency is declared

Fukushima Radiation Traced in Pacific Seafood 25 Oct 2013 Just offshore from the Fukushima plant, scientists from the Woods Hole Oceanographic Institution in the United States are working alongside their Japanese counterparts, monitoring radiation levels. Among them is senior marine chemist Ken Buesseler. "That radiation is moving across the Pacific, but it gets much, much lower even short distances offshore," he said. Buesseler said a bigger concern is the accumulation of isotopes in marine life. Earlier this year, cesium isotopes from Fukushima were found in tuna caught off California.

This is the bioaccumulation and bioconcentration effects I mentioned in a post above - a well known biological effect: Atoms or molecules are ingested or absorbed by plants/animals low on the food chain and as they are in turn eaten by higher and higher animals on the top of the food chain, the concentrations of these undesirable substances is increased by up to 1000 to 100,000,000 times - depending on many factors. At the very top of the current food chain for many to most things are humans.
