The Chief has actually seen some other peer-reviewed scientific papers about low level radiation being beneficial to living cells and organisms. Like water, sodium, zinc, copper, and many other substances, some is helpful (and in some cases even ESSENTIAL), while too much of the same thing can be harmful, up to the level of fatality.
With the terrible earthquake and resulting tsunami that have devastated Japan, the only good news is that anyone exposed to excess radiation from the nuclear power plants is now probably much less likely to get cancer.
This only seems counterintuitive because of media hysteria for the past 20 years trying to convince Americans that radiation at any dose is bad. There is, however, burgeoning evidence that excess radiation operates as a sort of cancer vaccine.
As The New York Times science section reported in 2001, an increasing number of scientists believe that at some level — much higher than the minimums set by the U.S. government — radiation is good for you. “They theorize,” the Times said, that “these doses protect against cancer by activating cells’ natural defense mechanisms.”
Among the studies mentioned by the Times was one in Canada finding that tuberculosis patients subjected to multiple chest X-rays had much lower rates of breast cancer than the general population.
And there are lots more!
Take away message: without absolute evidence, don’t sweat the small stuff!
