I was pricing out new counter tops, and was thinking of doing prefab granite for kitchen. Then I come across this little gem.
I had never heard this before, but I guess it's been out for around a year now.

What?s Lurking in Your Countertop?
SHORTLY before Lynn Sugarman of Teaneck, N.J., bought her summer home in Lake George, N.Y., two years ago, a routine inspection revealed it had elevated levels of radon, a radioactive gas that can cause lung cancer. So she called a radon measurement and mitigation technician to find the source.
?He went from room to room,? said Dr. Sugarman, a pediatrician. But he stopped in his tracks in the kitchen, which had richly grained cream, brown and burgundy granite countertops. His Geiger counter indicated that the granite was emitting radiation at levels 10 times higher than those he had measured elsewhere in the house.
