I am always pleased when one of my crank folk medicine theories is proven to be true, or at least possible. It turns out that low-level X-Rays might be much more dangerous than we had thought. In fact they might even be more dangerous than high-level X-Rays, because the cells do not repair themselves in the same way. Keep this in mind when you visit the dentist, I haven’t let them do this to me for six years now, despite continual entreaties and guarantees that it is safe. I picked this fact up from the January 2004 issues of Discover magazine, which covers the 100 biggest science stories of the year, go buy a copy and catch up on a year’s worth of science reading, not yet on-line.
