These Indoor Plants Do More Than Just Look Good – They Fight Radon!
When you think about indoor plants, what comes to mind? Perhaps it’s the calming greenery, the splash of color, or even the fresh oxygen they provide. But did you know that some of these leafy friends do more than just brighten up a room? That’s right—certain indoor plants can actually help improve the air quality in your home by reducing harmful substances, including radon decay products. For suburban homeowners like you, who might have a basement or spend a lot of time indoors, this could be a game-changer!
Understanding Radon and Its Impact on Health
Before we jump into which plants are the best radon fighters, let’s talk a little about radon itself.
What is Radon?
According to Health Canada, radon is a naturally occurring radioactive gas that forms when uranium in soil, rock, and water breaks down. It can seep into homes through cracks in the foundation, gaps around pipes, and other openings. Because radon is colorless, odorless, and tasteless, you can’t detect it without proper testing.
Health Risks Associated with Radon
Why should you care about radon? Well, radon exposure is the second leading cause of lung cancer in the United States, according to the United States Environmental Protection Agency (US EPA). For non-smokers, it’s the number one cause. Check out our online calculator to compare your radon exposure vs cigarettes smoked. Long-term exposure to high levels of radon can significantly increase your risk of lung cancer. And here’s a startling fact: about 1 in 15 homes in the U.S. has elevated radon levels!
Why Radon is a Concern for Homeowners
If you’re a homeowner, especially in a suburban area where basements are common, radon should be on your radar. Basements and ground-floor living areas tend to have higher radon levels because radon gas rises from the soil and enters through cracks and gaps. Even if you don’t spend much time in your basement, radon can still find its way into the rest of your home, affecting everyone inside.
The Role of Indoor Plants in Air Quality
Now that we’ve covered why radon is a concern, let’s talk about how indoor plants can help.
How Plants Improve Indoor Air Quality
Indoor plants are nature’s air purifiers. They improve air quality by:
Producing Oxygen: Plants release oxygen through photosynthesis, which can help freshen the air in your home.
Regulating Humidity: Plants release moisture into the air through a process called transpiration, which can help maintain optimal indoor humidity levels.
Removing Toxins: Some plants can absorb airborne pollutants like formaldehyde, benzene, and trichloroethylene through their leaves and roots.
The Science Behind Plants and Radon
While plants don’t directly absorb radon gas, they can help reduce radon decay products—tiny particles that attach to dust and other airborne substances and can be inhaled, posing a health risk. By improving overall air quality and circulation, plants can help reduce the concentration of these particles.
