Fraser Valley Radon - Radon Information

Radon is a naturally occurring radioactive gas that can be found in the soil and rock beneath homes and buildings. It is colorless, odorless, and tasteless, making it imperceptible to human senses. Radon is formed by the decay of uranium in the soil.

Here are some key points about radon gas in homes:

Health Concerns:

  • Radon is the second leading cause of lung cancer after smoking.

  • Prolonged exposure to elevated levels of radon can increase the risk of developing lung cancer, particularly in smokers.

  • Radon gas decays into radioactive particles that can be inhaled into the lungs, where they can damage lung tissue over time.

Entry into Homes:

  • Radon typically enters homes through the ground and can accumulate to higher levels indoors than outdoors.

  • It can enter buildings through cracks in the foundation, gaps around service pipes, construction joints, and other openings in the foundation.

Geographic Variation:

  • Radon levels can vary significantly from one region to another. Even from one neighbouring house to another. One house can be well within safe levels, while the house right beside it can have extremely high levels.

  • Certain geological formations and soil types are associated with higher radon levels.

  • The only way to determine the radon levels in a specific home is to conduct a radon test.

Radon Testing and Radon Mitigation:

  • Radon testing is the only way to know if a home has elevated levels of radon.

  • If elevated levels are detected, radon mitigation systems can be installed to reduce indoor radon concentrations. Common mitigation methods include soil suction, sub-slab depressurization, and ventilation systems.

Regulations and Guidelines:

  • Various countries and regions have established guidelines and regulations regarding acceptable levels of radon in homes. It is essential for homeowners to be aware of and comply with local regulations.

  • Health Canada recommends a reference level of 200 Bq/m³ (becquerels per cubic meter) as a basis for taking action to reduce radon levels in homes.

Prevention:

  • New construction radon mitigation systems can incorporate radon-resistant features to minimize radon entry.

  • Regular radon testing, especially in areas prone to high radon levels, is important for maintaining a healthy indoor environment.

Awareness and Education:

  • Public awareness about radon and its health risks is crucial.

  • Homeowners should educate themselves about radon and take appropriate measures to test and mitigate for radon, if necessary.

  • It's important for homeowners to be proactive in testing for radon and taking steps to mitigate elevated levels to ensure a healthy indoor environment. If you are concerned about radon in your home, consider contacting a local radon professional or your health department for guidance.
