Radon Detection and Reduction questions, answered by experts

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.
