Is Any Level of Radon Safe?

A good analogy is is a blindfolded person throwing darts at a dartboard. The probability of hitting a bulls eye increases with the number of darts thrown at a time, and how long a person continues to throw darts.

It’s the same with radon exposure. The longer we are exposed and the greater the concentrations we are exposed to, the greater the likelihood radon will give us lung cancer.

In short, the only safe level of radon exposure is when there is no radon. In other words take the darts away from the person.

Although it is not always feasible to remove all of the radon, the wise course is to limit our exposure to it as much as possible.

How Do You Remove Radon?

Think of radon like ground water.  If you had ground water seeping into your basement, you would dig a hole below the concrete floor, and create a pit to collect the water.  You would install a sump pump to remove the water before it rose high enough to seep into the basement.

We do the same thing to remove radon.  We drill a 5 or 6 inch hole in the concrete floor.  We adapt that to a 4 inch pipe, and run that pipe into the attic.  In the attic we attach a fan to the pipe and run it out through the roof.  The fan creates low pressure below the floor.  As radon gas comes up through the soil, it is drawn along the gravel bed and is pulled up the pipe and outside the house.  We collect it and remove it before it enters the house. We use a similar technique with houses that have crawl spaces.
