What is Radon?

Radon is a naturally occurring radioactive gas that is colorless, odorless, and tasteless. It forms from the decay of uranium, thorium, and radium found in rocks, soil, and groundwater. Radon can enter buildings through cracks in floors, walls, and foundations, as well as through openings around pipes and wires. Once inside, it can accumulate to levels that pose serious health risks.

Testing and Mitigation

The only way to determine if your home has elevated radon levels is through testing. If radon levels exceed 200 Bq/m³, homeowners should take corrective actions such as improving ventilation or installing sub-slab depressurization systems to reduce radon concentrations. Mitigation strategies can include installing a radon reduction system, sealing cracks in floors and walls, and improving ventilation.

Protecting Your Health

To minimize the health risks associated with radon:

Test your home for radon, especially if it has never been tested, during real estate transactions, or after renovations.

Seal cracks and openings in your home's foundation to reduce radon entry

If radon levels are elevated, consult a professional to install a mitigation system.

Avoid smoking indoors, as it significantly increases the risk of lung cancer from radon exposure.
