If you have been reading this blog for a while, you will know that we had a radon issue when we moved into this house. The house inspector tested the air and said that it read 11.4. You are supposed to do something about it if it is over 4.

Therefore I installed a big pipe through my house from my sump to carry the radon gas out through the roof. A vent fan in the attic now runs all of the time and is supposed to be depressurizing the soil beneath our house. There was some question in my mind as to whether I was getting enough suction since it only measures 0.9" water column.

Last week I bought a radon gas monitor and it has been sampling the air in the basement ever since. It reveals that the readings are down to 0.9. That seems like a big improvement from 11.4. When I get some spare time I may seal up the system a little more to try to improve the numbers. In the mean time it is at least at a much safer level.
