Geiger counters can't measure for radon in granite

Videos using Geiger counters to measure for radon in granite are typically done for dramatic effect.

While Geiger counters can see radiation in granite, they cannot measure for radon because they do not differentiate between the multiple radioactive elements (some of which pose no risk, such as Potassium) found in granite. Hence, they typically over-respond.

I do radon measurement testing in my state and this is very informative. Too many people are giving incorrect facts on this matter. I've checked your web site and will use it for reference. I've talked with other testers and they are coming up with stories of people being told to tear out their granite counter tops because their full of radon gas. People will down anything to pray on peoples fears.

Thanks for posting.
