Radon testing is a simple but important step in protecting your home and health. Radon is a colorless, odorless radioactive gas that forms naturally in the ground and can seep into homes through cracks in foundations, floors, and walls. Because you can’t see or smell it, testing is the only way to know if radon levels are elevated.
The basics of radon testing start with understanding the two main types of tests: short-term and long-term. Short-term tests typically last between 2 and 7 days and are often used for quick screenings, especially during real estate transactions. Long-term tests run for 90 days to a year and provide a more accurate picture of your home’s average radon level over time.
Radon test kits are usually placed in the lowest livable area of the home, such as a basement or first floor. They should be positioned away from windows, doors, and vents to avoid interference. During testing, it’s important to keep windows and doors closed as much as possible to ensure accurate results.
Once the test is complete, results are measured in picocuries per liter (pCi/L). The Environmental Protection Agency recommends taking action if radon levels are 4.0 pCi/L or higher. If elevated levels are found, professional radon mitigation systems can effectively reduce radon in the home.
Overall, radon testing is affordable, non-invasive, and easy to do. Whether you’re buying a home or have lived in one for years, understanding the basics of radon testing helps ensure a safer indoor environment for you and your family.
