Wyoming Radon Levels

Zone 1 counties have predicted average indoor radon screening level greater than 4 pCi/L (picocuries per liter) (red zones)
Highest Potential
Zone 2 counties have predicted average indoor radon screening level between 2 and 4 pCi/L (picocuries per liter) (orange zones)
Moderate Potential
Zone 3 counties have predicted average indoor radon screening level less than 2 pCi/L (picocuries per liter) (yellow zones)
Low Potential

Radon is naturally occuring radioactive gas that is colorless, odorless, and tasteless. It is formed by natural breakdown of uranium in rock, soil, and water

Radon gas moves up through the soil and can be drawn into our homes by slight pressure differences. Once inside, radon can become trapped and build up to unsafe levels

State Breakdown
