Radon Gas - What Can I Do Myself?

Some relatively easy and minor mitigation techniques that can be done by a non-professional are:

Increase the ventilation in your home (open windows and doors whenever possible.)

Limit the amount of time anyone spends in the areas of your home which have the greatest radon concentration (for example, the basement.)

If your home has a crawl space, keep the crawl space vents on all sides of the house fully open all year.

Stop smoking and discourage smoking in your home.
