Everything you need to get started.

  • Invisible

    Radon is a colorless, odorless, and tasteless gas. Only a detector can reveal its presence.

  • Cancer Risk Factor

    Radon is the second leading cause of lung cancer, especially among non-smokers.

  • As Bad as Smoking

    Exposure to 4 pCi/L of radon equals the risk of smoking 8 cigarettes per day.

  • Always Changing

    Radon levels fluctuate constantly due to weather, season, and ventilation conditions.

What is a Radon Detector?

A radon detector is a device that monitors radon gas levels indoors. Radon is a colorless, odorless radioactive gas that can build up over time and pose health risks. Regular monitoring helps ensure a safe living environment.

Where Is Radon Most Common in the U.S.?

In the U.S., radon is most common in the Midwest, northern states, and mountainous regions. Key points per the EPA:

- High-risk (red zones): Iowa, North Dakota, South Dakota, Minnesota, Wisconsin, Illinois, Nebraska, Colorado, and parts of Pennsylvania/Ohio, where levels often exceed 4.0 pCi/L.

- Medium-risk (orange zones): Areas surrounding high-risk regions with moderate radon levels.

- Low-risk (yellow zones): Southern and coastal states with lower radon levels.

Risk differences stem from local soil and geological factors affecting radon seepage into buildings.

How Radon Enters Your Home?

Radon seeps into homes from soil gas, which forms as uranium in bedrock and topsoil decays. It creeps in through pathways like cracks in foundations, drains, crawl spaces, dirt floors, and even gaps around fittings or windows. Trapped indoors by poor ventilation, it can build to risky levels. Test your home and seal these entry points to stay safe!

Radon Levels & Actions

To minimize radon exposure, choose low-emission building materials when possible. For newly renovated homes, use a radon detector to confirm safe levels before moving in. If you live in a high-risk area (check local government or EPA maps), consider long-term monitoring with a reliable radon detector. When levels are elevated, improve ventilation by opening windows or using exhaust fans. For persistent issues, seal foundation cracks or install professional mitigation systems to ensure safety.
