I assume you are kidding about it killing me... I hope. I was thinking of getting a geiger counting if this is the case. Also would like to check my granite countertops.
It is an active system with the inline fan. The home instpector checked it out and it is working. When you turn it off, the pressure tube thing moves. He said I should probably get it replaced in about 5 years and to check it once every quarter. Also, I had a radon test done and it can up low at .4 whatever the ending is. I ordered a self test off amazon to retest to just make sure the previous owner didn't mess around and open the windows while it was running.
