IamA Radon Mitigation Technician. Ask me absolutely anything.
I've been working in Radon Mitigation for almost a year. Posted a thread a few days ago that got deleted because I posted without the sign with my username. Had two questions: Weirdest superstitutions/misinformation? People who believe they can see Radon. What test should I buy? Don't. You can get them mailed to you from almost any mitigation company and a lot of the ones you buy are hilarious rip offs.
