Afraid of a little radiation are you? Thinking that some unmeasurable uranium atom might come floating over and ZAP you? Death by some horrible cancer monster? Do you think that billions of people had 2-headed babies from the atomic bombs?
Well, perhaps you should read once in a while. This is quite a comprehensive article, and I think it's fairly true. I suspect that Humanity sprang from a zone of fairly high radiation, and took care of it. Our fear of radiation is much greater than a fear of smoking, and this is irrational. As more studies are done in the cess-pools of radiation accidents, we will know what the human body can take. And for us old guys, a good hike to the top of Mt. Everest, and the attendant heavy dose of cosmic rays probably zaps out any old cancer cells lying about.
So, have a crème brûlée, pour a brandy, light up a cigar, and forget those radiation scares.
