January is Radon Action Month, a time dedicated to raising awareness about the dangers of radon exposure and the importance of testing and mitigating this silent threat. Radon is a leading cause of lung cancer among non-smokers, making it a significant health risk that homeowners should not ignore. Here’s what you need to know about radon and how to protect your family this winter.
What Is Radon?
Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil, rock, and water. It can seep into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or drains. Because radon is colorless, odorless, and tasteless, it’s impossible to detect without specialized testing equipment.
Why Is Radon Dangerous?
Radon becomes hazardous when it accumulates in indoor spaces, particularly during the winter months when homes are sealed to conserve heat. Long-term exposure to high levels of radon increases the risk of lung cancer, with the Environmental Protection Agency (EPA) estimating that radon causes about 21,000 lung cancer deaths annually in the United States.
How Does Radon Enter Your Home?
Radon gas can enter through:
Cracks in floors, walls, or foundations.
Construction joints.
Gaps around pipes, cables, or service lines.
Sump pumps or drains.
Well water, in rare cases.
Testing for Radon
The only way to know if your home has elevated radon levels is to test for it. Here’s how:
Purchase a Test Kit: Affordable radon test kits are available at hardware stores, online retailers, or through your state’s radon program.
Hire a Professional: Certified radon measurement professionals can conduct more detailed assessments and provide immediate results.
Follow Testing Guidelines: For accurate results, place the test kit in the lowest level of your home that is regularly used, and avoid testing during severe weather or unusual ventilation conditions.
Understand the Results: The EPA recommends taking action if radon levels in your home exceed 4 picocuries per liter (pCi/L). However, even lower levels can pose risks over time.
Reducing Radon Levels
If your home has high radon levels, mitigation systems can help:
Install a Radon Mitigation System: These systems use ventilation to direct radon gas out of your home before it accumulates.
Seal Entry Points: Seal cracks and openings in floors and walls to reduce radon entry.
Improve Ventilation: Increase airflow in your home, especially in basements or crawl spaces.
Winter Precautions
Winter is an ideal time to test for radon because homes are often sealed tightly, which can lead to higher indoor radon concentrations. Take these additional steps during the colder months:
Test Early: Begin testing at the start of the season to allow time for mitigation if needed.
Monitor Levels Regularly: If you’ve previously tested, consider a follow-up test to ensure radon levels remain safe.
Check Mitigation Systems: Ensure existing radon mitigation systems are functioning properly.
Radon Safety and Awareness
Spread awareness about radon safety by:
Talking to Neighbors: Encourage others in your community to test their homes.
Participating in Radon Events: Join local workshops or awareness campaigns during Radon Action Month.
Contacting Local Resources: Reach out to state radon programs for guidance, test kits, and certified professionals.
Radon is an invisible threat, but with awareness and action, it’s one you can control. Take advantage of Radon Action Month to test your home, protect your family, and contribute to a healthier community. For more information, visit the EPA’s radon page or contact your state’s radon office.
Be proactive this January and ensure your home is a safe haven from radon exposure.
