Radon zones


	Zone 3 (0 counties)
	Zone 2 (39 counties)
	Zone 1 (53 counties)

	Highest Potential: counties have a predicted average indoor radon screening level greater than 4 pCi/L (pico curies per liter) (red zones)
	Moderate Potential: counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones)
	Low Potential: counties have a predicted average indoor radon screening level less than 2 pCi/L (yellow zones)
