Take 0.125 mSv and Call Me in the Morning.

I remember reading about a study that had been done on people in the Ozarks who lived in areas of higher than normal radon gas. The study found that those people showed a lower than normal rate of cancer. I’m not sure if these findings are on the same level as radon is a different kind of radiation. One thing, if this does prove to be true, the believers in homeopathic medicine should be over joyed. Either way, it’s good to be a vole living near a nuclear research facility.
