Radon: The Invisible Threat in Your Home
Written By Dustin Harpe
For years I thought that radon was just an excuse for people to make money testing your home and installing mitigation systems. I WAS WRONG! Here is a short article that will give you a better understanding of what radon is and what we can all do to reduce harmful exposure.
What is Radon?
Radon is a colorless, odorless, and tasteless gas that is produced from the natural breakdown of uranium in soil, rock, and water. It can seep into homes through cracks in foundations, floors, and walls, as well as through gaps around pipes and drains. Because it is undetectable without specialized testing, many homeowners are unaware of its presence until they take proactive steps to measure radon levels.
Why is Radon Dangerous?
Radon exposure is the second leading cause of lung cancer after smoking, according to the U.S. Environmental Protection Agency (EPA). Long-term exposure to high levels of radon can damage lung tissue and increase the risk of developing lung cancer, particularly among smokers. Since radon levels can fluctuate, continuous or periodic testing is necessary to ensure safety over time.
How Does Radon Enter Homes?
Radon primarily enters homes through:
- Cracks in the foundation and walls
- Gaps around pipes and sump pumps
- Spaces in construction joints
- Well water supply (in some cases)
Basements and lower levels of homes are particularly susceptible to radon accumulation due to their close contact with the ground.
How to Test for Radon
Testing for radon is simple and relatively inexpensive. Homeowners can choose from:
- Short-term radon tests: These tests measure radon levels over 2-7 days and provide a quick indication of whether further testing is needed.
- Long-term radon tests: These tests measure radon over 90 days to a year, providing a more accurate representation of average exposure levels.
- Professional radon testing: Certified radon measurement professionals can conduct thorough assessments using specialized equipment.
How to Reduce Radon Levels
If high levels of radon are detected in a home (4 pCi/L or higher as recommended by the EPA), mitigation measures should be taken. Common radon reduction techniques include:
- Sealing cracks and openings in floors and walls to reduce radon entry.
- Installing a radon mitigation system, such as a sub-slab depressurization system, which uses pipes and a fan to redirect radon gas away from the home.
- Increasing ventilation by using air exchange systems or opening windows when possible.
Protecting Your Home and Health
Regular radon testing and mitigation, if necessary, are crucial for ensuring a safe indoor environment. Whether you are buying a new home, renovating, or simply looking to improve indoor air quality, radon awareness should be a priority.
By taking proactive steps to test and mitigate radon exposure, homeowners can protect themselves and their families from this invisible but serious health threat. Don’t wait until it’s too late—test your home for radon today and take control of your indoor air quality.
