it is much worse than what you think, there is a mass of debris the size of california, about to hit the west coast of america, there are masses of polar bears with open wounds and nearly no fur being found in alaska, not to mention 50 percent of walrus and seal pups from last breeding season are laying dead on alaskan coastline.
the whole of the pacific region is heavily radiated, and i suggest no one eat anything from that region, but within a few years most sea life will be gone in that region, eventually everywhere
as for humans.......... we will see, look after thyroids people, plenty of cancer cures around if you know where to look
