Debris from the 2011 tsunami in Japan has reached North America. Plastic bottles, children’s toys, and insulating foam from buildings is washing up on beaches in the Alaskan panhandle. Although it is estimated that 70% of the tsunami debris has sunk, it is also estimated that as much as 1.5 million tons is headed for North America.
Well I know you’re an educated propagandist Anti-Elvis, but you aren’t implying radioactive mass floats are you? So, what’s the threshold? Anything with more than 82 protons (82 Pb Lead 207.2) is radioactive. There are lot’s of isotopes, and other forms of elements which are radioactive, but their half lives are measured in minutes and seconds. If it didn’t get scattered into the atmosphere and through the air after an explosion, it will not get here.

It’s the radioactive beach balls and air mattresses we have to worry about.
From what I’ve read. most of the radioactive water from the Fukushima plant has either settled on the bottom offshore from Japan, or dispersed in the larger volume of the ocean – and not all of it is in the form of short-lived isotopes, so they’ll have their share of three-eyed fish and giant monsters that destroy Tokyo.
That doesn’t mean there may not be radioactive debris that survived the trip across the Pacific, but I imagine the amount of such is pretty small. Still, just one radioactive Hello Kitty doll could ruin someone’s entire day.
