Key Radon Facts Every Homeowner Should Know
Radon is a colorless, odorless, naturally occurring radioactive gas that can be harmful at elevated levels. Radon testing is essential for detecting its presence in homes, schools, and workplaces. Here’s what homeowners should know about radon testing and steps to take if radon is detected.
What is Radon Testing?
A professional radon test measures the concentration of radon gas in the air to assess potential health risks. It is the only way to detect radon since the gas is invisible, tasteless, and scentless. Testing typically measures radon levels in picocuries per liter of air (pCi/L), and high levels can accumulate indoors, especially in areas with poor ventilation.
Radon is Present Across the U.S.
High radon levels have been found in every state due to the natural breakdown of uranium in the soil, rock, and water. Even in regions where neighboring homes show safe levels, radon can still be present in your own home. Therefore, regular radon testing is necessary, regardless of geographic location.
Radon Levels Can Fluctuate
Radon concentrations can vary widely, even between neighboring houses. Testing is the only way to determine if your home has elevated radon gas levels.
Testing is Simple and Accessible
Radon testing is straightforward and can be done with D.I.Y. test kits or by hiring a professional company. Professional testing ensures accuracy and often includes advice on radon mitigation if elevated levels are found.
How Often Should You Test for Radon?
The EPA recommends testing at least every two years. Testing is essential after significant events like:
- Real Estate Transactions: Home sales often require testing to protect future occupants.
- Home Renovations: Remodeling can alter airflow patterns, potentially affecting radon levels.
- Post-Mitigation: If your home has undergone radon mitigation, testing ensures the system continues functioning effectively.
Types of Radon Tests
There are short-term and long-term radon tests available:
- Short-Term Tests: These tests last between 48 and 120 hours, providing a snapshot of radon levels.
- Long-Term Tests: These tests are used to monitor radon over three months to a year, and help identify fluctuations due to seasonal changes.
Methods for Conducting Radon Tests
Short-term radon testing typically involves placing a charcoal test kit in a closed house for at least 12 hours. After this period, the test is sent to a certified lab for analysis. Electronic radon detectors, which a certified technician can read, are also used for rapid results, especially during real estate transactions.
Long-term radon tests employ electronic monitors or alpha-track detectors, which track changes over time for a more comprehensive evaluation.
Testing is Affordable
Radon testing is relatively inexpensive, with D.I.Y. kits costing between $25 and $100, depending on the duration and type of test. Professional radon testing services offer accurate results and provide a plan for radon mitigation if high levels are found.
Understanding Radon Levels and Recommendations
The E.P.A. has set guidelines to help homeowners understand when radon mitigation may be necessary:
- Four pCi/L or higher: To reduce radon levels, immediate action is needed. Retest with a professional radon testing device and contact a certified contractor to install a radon mitigation system.
- 2-4 pCi/L: While not considered an emergency, installing a mitigation system should be considered.
- Below two pCi/L: No action is necessary, but regular testing every two years is still recommended.
Steps After Detecting High Radon Levels
Radon mitigation is a process that reduces radon concentrations in the home by using a system to vent the gas outside. Here’s what to expect during the mitigation process:
- Consultation with a Certified Radon Professional: A licensed radon contractor will assess your home and recommend a suitable radon mitigation system.
- System Installation: This process usually takes one day, depending on the complexity of the home’s structure. Pipes and a specialized fan are installed to draw radon gas away from your property.
- Post-Mitigation Testing: Once the system is installed, retesting ensures that the radon levels have been reduced to acceptable levels.
What to Look for in a Radon Testing and Mitigation Professional
Not all contractors are equally qualified for radon testing and mitigation. When selecting a radon service provider, ensure they meet these standards:
- Certification by the National Radon Proficiency Program (N.R.P.P.) or similar organizations.
- State licensing requirements, where applicable.
- Insurance and bonding.
- Post-testing radon mitigation system.
Safeguard Your Home from Radon Exposure
Regular radon testing and mitigation can help protect you and your family from the risks associated with radon gas. If you haven’t tested your home recently, it’s an excellent time to take action.
