Except that that's utter rubbish. Cessium distributes through the body evenly. The method of delivery has nothing to do with the exposure in this case. If you roll in it.....it distributes; if you breathe it....it distributes; if you drink it.....IT DISTRIBUTES! It stays in your body about 70 days. That sucks. All of japan is not dead from radiation sickness since 11 March 2011, I would say that so far we seem to be fairly safe. They're breathing a hell of a lot more of it than the guy in california, whose parents were subjected to years of open air weapons testing, and yes, DIDN'T DIE FROM RADIATION POISONING. Cows died several km from chernobyl because of thyroid dysfunction brought on by radiation poisoning, however this DETONATION and subsequent expulsion of massive amounts of material directly into the atmosphere didn't kill people the world over. Breathe.
