Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
