How big of a deal is radon? Recently did a $15 diy test that I mailed in, it came back 10.1 pCi/L, which apparently is above the EPA recommended 4 pCi/L. Which doesn't seem that drastic. Never really knew about this shit but apparently its significant killer statistically, but also it obviously seems like a huge business opportunity with all these low entry "certified" testers and guy who can run a pvc vent fan through your house. Also not a request thread, but was a basement dweller youth so I'm curious how fucked I am
