Radon Detection and Reduction questions, answered by experts

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.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.
