Anyone else get their homes tested for radon levels? We had two tests done, one in summer and one in winter. The latter is apparently more accurate. The summer test was 156bq winter was 256bq. Any comments? Anyone have the mitigation done in their homes? Thanks

If you have an air exchanger, make sure you are running it constantly-it will rid the build up, which is what causes the health problems. If not, you should find out from whomever did your testing about abatement details, as your reading is higher than it should be.  
 

The levels in your home are over the recommended level from Health Canada. How much time is spent in the basement. And how old is your house, newer homes need to have ground work done incase radon levels become to high. " 4inch pipe into concrete floor that can be accessible to vent outside if needed"

In winter with the cold outside and heat inside , there is more heat rising inside creating a stack effect that brings more radon in. Also, in our cold climate , there is less tendency to have any windows or doors open any longer than necessary which can dilute the radon a bit in the summer. Nothing wrong with testing in the summer but better to do a longer term test and capture some of the heating months as well. If you are only going to do a 3 month test , it is better to do in the winter because you are measuring when radon levels are probably highest and most dangerous to you.
