What is radon?

Radon is a naturally occurring radioactive gas that is a byproduct of uranium. Unlike some other hazardous gases, radon is undetectable by our senses; you can't see, smell, or taste it. It is present in both the air we breathe and the groundwater beneath our homes.

Why is radon dangerous?

Radon poses a grave threat to our health—it's the primary cause of lung cancer among non-smokers, responsible for approximately 21,000 American deaths every year. Long-term exposure to elevated radon levels can have devastating health consequences, making it a critical concern for homeowners.

Does my home have high radon levels?

Testing is the only way to determine if your home has elevated radon levels. Fortunately, it's usually easy and affordable to test for radon. You can purchase a radon testing kit or detector to use in your home. These kits are readily available and straightforward to use, offering a simple and effective way to safeguard your family.

What do I do if I detect dangerous levels of radon in my home?

If your radon test reveals high gas levels, taking immediate action is crucial to protect your family's health. Contact a qualified contractor experienced in radon mitigation. They will assess your home, seal any foundation cracks that allow radon to enter, and install a ventilation system to improve air circulation, effectively reducing Radon levels.

Although Radon testing may not have been on your list of priorities for January, it's an important safety measure that shouldn't be overlooked. Protect your loved ones by testing your home for radon and, if necessary, investing in mitigation measures. And radon isn't the only invisible danger lurking in our homes. To stay safe, healthy, and happy this year, consider exploring additional resources such as gas leak detectors and carbon monoxide detectors.

Don't let this silent threat go unnoticed. Prioritize radon testing and ensure your home remains a safe haven for you and your family.
