<Natural radiation is already pervasive.> I fail to see how this is relevant... so is sunlight, so lie in it all day every day??? Not to say I'm worried about Japanese radiation, but it's my understanding lot's of folks are worried about others sources, especially exposure by pregnant women and children? OTOH, I agree that very subtle low level radiation is a very interesting field... the field of biological communication via biophotons and all that is pretty interesting for example. Of course this could point to potential INCREASES of problems of the ever increasing radiation of various forms in our environment, not less. DAK

OT Our bodies are about 18% carbon, one atom in a trillion of which is C-14 with a half-life of 5700 years. For a well fed 220 pound American, that works out to be 18kg of carbon so the number of radioactive carbon 14 atoms per person is around 1,000,000,000,000,000. So there's about 170,000,000,000 C-14 decays in each person per year or about 5000 per second. I understand this is somewhat of a concern (behind numerous other economic and technical issues, and potentially political issues) with potential future attempts at long term freezing/hibernation, and also potentially reviving people who have themselves frozen hoping that in the future they can be thawed, revived, and cured. They are likely to pick up more radiation from the environment they are in, but even if you can shield most of that; freezing someone doesn't slow the radioactive decay in their own body (largely but not just C-14 decay). Over time that radioactive decay would cause damage. The radiation is very modest, and living people can heal the damage but if your frozen you don't heal.
