Are you implying the radon emitted from the granite countertops caused this gentleman's brain tumor? To my knowledge the only medical concern with radon is lung cancer. I am not a doctor but I suspect this gentleman's brain tumor was caused by something other than radon.
Or are you implying the radiation emanating from the granite countertops caused the brain tumor? How long must one be exposed to the radiation emanating from granite countertops before a brain tumor develops? Does the tumor form overnight? Or does it take years of exposure?
How do you measure one's exposure to the radiation emanating from the countertops? Obviously the closer one is to the countertop the higher the exposure. (I would expect it to be around the square of the distance. So your exposure at 10' away will only be 1% of your exposure at 1' away.)
No, I don't think those granite countertops caused this guy's brain tumor. But that looks great in an article that tries to scare people about the dangers of granite countertops.
