Actually, there almost certainly *is* a safe level somewhere; trouble is, we know very little about the chronic effects of low-level radiation. So the health calculations all assume that the effects are linear right down to zero. The idea that they assume a "safe threshold" is a vicious lie promulgated by the more fanatical antinuclear people. Granted, all radiation is dangerous. Including the radiation from, say, a coal-burning power plant's exhaust. Yes, coal-burning plants do emit radioactive materials: there are natural radioactive isotopes in coal, as in most other things, and they end up in the atmosphere when the coal is burned. A coal-burning power plant of a given capacity emits *far* more radioactive junk than a comparable nuclear plant. In fact, it emits more than the nuclear plant is *allowed* to emit; if coal power plants were subject to the same rules as nuclear plants, they would all be shut down at once. Nuclear plants in fact emit very little radioactive material. I probably got more radiation exposure from my trip to Salt Lake City (which has a higher background radiation level because of its higher altitude) than I would from living next to a reactor for years. The only reason I say "probably" is that I haven't checked the numbers; I'm almost sure of it. >I can't believe this. This man is comparing "a few centuries" worth of >high-level radioactive waste with a fall from a rooftop. This is incredible. Frankly, I would take a slight rise in the background radiation level over the fall from the rooftop any day. Falling from a rooftop has a high probability of being fatal. More seriously, why the hell *not* compare them?!? The two are different animals only if your attitude toward radiation is ignorance and hysterical fear. Both can kill you. Both involve quantifiable risks. Which involves the least risk per kilowatt-hour of power? Turns out to be nuclear power. This may be surprising, but there is nothing incredible about it. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
