Written by If you’re spending a lot of time at home, it’s worth paying attention to something you can’t see or smell—radon gas. This invisible radioactive gas can sneak into your home through cracks in the foundation, crawl spaces, and even through your water supply. In the middle of this concern, one thing that helps keep your living space safe is proper ventilation. That’s where regular monitoring comes in too. Whether you’ve just moved into a new house or have been living there for years, staying on top of radon levels should be part of your routine. Even if you have a high-tech system like an AMG Eagle, it’s not enough to set it and forget it.
Why Radon Matters at Home
Radon is a naturally occurring gas that forms when uranium in soil and rock breaks down. The problem starts when it builds up indoors, especially in basements or lower levels. It can increase the risk of lung cancer over time. Long-term exposure is the real issue, not a quick weekend at grandma’s. That’s why taking radon seriously at home can really make a difference in your family’s health.
The Basics of Radon Testing
Testing for radon isn’t as complicated as it might sound. You can use a short-term or long-term test. Short-term tests stay in place for about 2 to 7 days, while long-term tests work for over 90 days. The longer you test, the more accurate your results will be. Either way, testing gives you a clear idea of what you’re dealing with. No guesswork needed—just real numbers that you can work with.
Where to Place Your Radon Test
Where you put the test matters a lot. You’ll want to place it in the lowest lived-in level of your home, typically the basement. Avoid putting it near windows, vents, or exterior walls. These spots can affect the readings and give you false results. Pick a room that gets regular use but doesn’t have a lot of drafts or fans running constantly.
What Those Radon Numbers Mean
After your test is complete, it’ll give you a reading in picocuries per liter (pCi/L). The EPA suggests taking action if your radon level is 4.0 pCi/L or higher. Even levels between 2.0 and 4.0 might warrant some attention. Lower is always better when it comes to radon. If your levels are too high, don’t panic—ventilation can help bring those numbers down.
Natural Ventilation: Is It Enough?
Opening a window might seem like a simple fix, but it’s not reliable in the long run. Natural airflow can help reduce radon levels temporarily, especially during mild weather when you can keep windows open for longer. But it’s not a permanent solution. The effect depends on outdoor conditions, so it’s too unpredictable to count on day after day.
Mechanical Ventilation: A Better Bet
This is where things get more consistent. Using mechanical ventilation means installing systems that pull fresh air in and push stale air out. A good example is a heat recovery ventilator (HRV) or energy recovery ventilator (ERV). These systems help keep air circulating without making your house drafty. They’re especially useful in colder climates where opening a window isn’t practical most of the year.
Sub-Slab Depressurization: A Common Fix
If your radon levels are too high, a system called sub-slab depressurization is often used. It works by creating a low-pressure zone under your home’s foundation. That way, radon gets sucked out before it has the chance to enter your house. The fan in this setup runs all the time and needs regular checks to make sure it’s doing its job right.
Keeping an Eye on Things: Why Monitoring Matters
Ventilation helps reduce radon, but it doesn’t work alone. You still need to keep an eye on the levels. Monitoring is key to knowing if your system is working the way it should. You can get digital radon detectors that constantly measure levels and show real-time results. Some even send alerts to your phone. This makes it easy to track any changes and catch problems early.
Seasonal Changes Can Shift Radon Levels
Here’s something many people don’t think about: radon levels can change with the seasons. They tend to rise in the winter because houses are sealed up tight, and that traps more radon inside. So, even if your home tested safe last summer, it might not be the same story in January. That’s why year-round monitoring is a smart move.
Keeping Your System in Shape
Just like any equipment, your ventilation system needs some attention now and then. Check your radon mitigation system at least once a year. Look for signs that the fan is running properly and check for blockages in the pipes. A maintenance check doesn’t take much time, but it can save you from bigger headaches later on.
When to Call in the Pros
If you’re not sure whether your system is working or if your radon levels aren’t dropping, it’s a good time to bring in a professional. Certified radon contractors can assess the situation and recommend adjustments or upgrades. It’s better to handle it early than wait for the problem to get worse.
Final Thought:
Living with radon in your home sounds scary, but it doesn’t have to be. With proper ventilation and regular monitoring, it’s something you can manage. Keep an eye on your numbers, keep your systems running smoothly, and don’t ignore changes. A little attention goes a long way when it comes to keeping the air in your home safe. You don’t have to overhaul your life—just take a few smart steps and follow through.
