<human>: How can I make sure that my home is safe from radon gas?
<bot>: The best way to make sure your home is safe from radon gas is to test for it. You can purchase a radon detector and have it professionally installed in your home. This will help you identify any areas of the home with high levels of radon, allowing you to take action to reduce or eliminate them. Additionally, if you are planning on buying or selling a home, you may want to consider having it tested before closing.
