That's what is really amazing about this whole supposed "debate." I can point out that the air pollution from coal-fired is four or five orders of magnitude more dangerous than radioactive nuclear waste, but that would be only part of the story. The simple fact is that, per unit of energy produced, the radioactivity in the *coal* waste is greater than the radioactivity in the *nuclear* waste. It's just more concentrated in the nuclear waste -- but that's an advantage, because that makes it much easier to manage. (Think of having trash concentrated in cans rather than scattered all over the landscape.) Yet people continue to fall for the old cliche' that "nuclear waste is dangerous for hundreds of thousands of years." The sheer ignorance of people who parrot this one has always amazed me. First of all, chemical waste isn't dangerous for just "hundreds of thousands of years," it is dangerous *forever*. It has an *infinite* halflife. A long halflife means weak radioactive emissions. In fact, the toxicity of long-lived radioisotopes is essentially chemical. > Hmmm. Let me put it this way instead.

That study and others have found that a nuclear meltdown would have to occur every two weeks to equal the damage done by the *routine* emissions from coal-fired power.
