I need some help clarifying some Radon questions I have. First of all I just watched our local TV channel talking about Janurary being “Radon Awareness Month” & they showed our State Radon guy putting up free test kits in the TV station (results on tonites 10:00 p.m. news) & I noticed he thumb tacked one on the ceiling by what appeared to be a speaker cover, it didn’t really look like a heater vent & was surely not a cold air return. I thought you were not to put them by any area that could have any kind of air movement, maybe not to much through a speaker cover ? I don’t know ??? The kits I’ve seen says “Hang at breathing level” Also monitors t least 20" above the floor.??
Also if there can be so much fluctuation in levels from one side of the room to the other, (The state guy said this too) how do you explain the integrity of the test with so much variation in recorded levels to the buyers/sellers/etc. If one side of room tests (below reccommended remediation level) 3.9 pCi/L one time & 4.2 pCi/L the next & visa versa with the other side of the room ? Or even higher that really may need remediation. I read a post on here awhile back about an inspector who had a client who was asking for a refund due to his test being high & the client had another test ran by someone else that showed normals. What gives ??? Is this why a lot of inspectors don’t bother with the possible headaches of the variations with this stuff ?? :shock:
