Q: How does radon enter my home?

• <div><p>Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.</p></div>

Q: What does air quality testing include?

• <div><p>Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.</p></div>

Q: Is there a safe level of radon?

• <div><p>No level of radon is technically safe, but because it&rsquo;s everywhere&mdash;even in the air outside&mdash;it&rsquo;s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.</p></div>

Q: How are samples collected during testing?

• <div><p>Through air sampling devices and surface swabs in key areas of concern.</p></div>

Q: Where is radon commonly found in a home?

• <div><p>Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.</p></div>
