Before we get into the details, let’s understand what exactly radon is and why it is a cause for concern.

What is Radon?

Radon is a naturally occurring radioactive gas that is formed through the decay of uranium, which is found in the soil and rock beneath our homes. It is a byproduct of the natural breakdown of uranium and can seep into buildings through cracks in the foundation, walls, gaps around pipes, or any other openings. Radon can also be present in well water and released into the air when the water is used for activities like showering or doing laundry.

Radon is classified as a Group 1 carcinogen by the World Health Organization (WHO), meaning it is known to cause cancer in humans. Prolonged exposure to high levels of radon gas is the second leading cause of lung cancer, after smoking. In fact, the Environmental Protection Agency (EPA) estimates that radon causes about 21,000 lung cancer deaths in the United States each year.

Since radon is invisible and odorless, it is impossible to detect its presence without proper testing. That is why radon home inspections are crucial in identifying if there are elevated levels of radon in your home.

The concentration of radon in a home can vary significantly depending on several factors, including the underlying geology of the area, the construction of the home, and ventilation. Even homes in low-radon areas can have elevated radon levels if there are cracks or openings that allow radon to enter.

It’s important to note that radon is not just a concern for older homes or homes located in specific regions. Any home, regardless of age or location, can have radon issues. Therefore, it is recommended that all homeowners consider getting a radon home inspection to ensure the safety of their household.
