Hi
Does any one know if I place the radon continuous monitor on a kitchen granite countertop will affect the accuracy of the radon test? Thanks
Its best to check with the manufacturer of your device.
You don’t test in kitchens, bathrooms, or other high humidity areas.
The stone may put off radon gas but it is likely insignificant.
Note, you need more training.
You can check granite tops if you like.

Not the question the OP was asking.
I know. Just giving him more info as others have addressed his question.
