Re: That dirty yard in the neighbourhood
slight radioactivty in my kitchen due to the granite countertop
Yup - granite is a known source of radiation due to the low levels of Potassium-40, thorium and (in some granites) low levels of uranium.
My wife's parents both died of cancer - her father was a stonemason who worked with granite for most of his life and her mother was exposed to granite a lot for most of her life. I'm hoping that my wife's years away from it will reduce her chances of cancer..
