Hi, folks!

Interesting article about radon in granite countertops.

Over the years I have come across a number of granite installations

that have emitted radon. The case that I remember most clearly was a home in

Southern California that tested with approximately 6 pCi of radon per liter in

most of the house. The guest bedroom was tested and had almost 30 pCi. It

turned out the source was two granite headboards for the twin beds. Removing

the headboards to the detached garage reduced the radon level in the home to

under 0.5 pCi.

The homeowner said he wasn’t at all concerned because

the only person that ever slept in the guest bedroom was his mother in law.
