Myth #8 – Radon tests are expensive and take a long time. This myth is easily dispelled when put in the context of all the facts.
Fact: Do it yourself tests can be as little as $15, however if strict protocols are not followed inaccurate results will result. A professionally administered test by a certified radon technician will cost about $150. These take 2-7 days and are normally done in association with a real estate transaction. When compared to the potential health risks, getting a radon test costs less than going to the dentist.
