Hills Can Impact Radon Levels

If you live on a hill, this can impact the radon levels in your house. We recently installed a radon mitigation system on a hill. We could accurately determine the radon because the Jordan Reservoir was at 6,618 and the house was at 7,030 feet from the blueprints. There is an elevation differential of 412 feet. 

When the wind comes up, you can think of it as a piston pushing gases into the ground. The normal winds are about 10 miles per hour. However, when there are high winds the velocity can get up to 40 to 50 miles per hour. Imagine if you put you had out the call at 40 miles per hour. Think of the push back.

We installed a radon mitigation system and reduced the level from 10.3 to 0.8. When the system was installed we got an average of 0.8 over a two day period. After the wind picked up the radon was elevated to in excess of 20 pCi/L for a day. However, if we averaged the average over a one year period of time the average is closer to 1.7. It is the long term average as composed to short term average that has the health risk from radon gas.
