Radionuclides in Air and Water: Overview

Radionuclides in air and water are brought directly into our bodies as we breathe and drink. Once there, they may lodge in our lungs or digestive tract and continue to emit radiation directly to living tissue. EPA protects people from these exposures through its regulatory programs to control air emissions and by setting standards for removing radionuclides from drinking water. Through its voluntary programs, EPA encourages homeowners to help protect themselves and their families by testing their homes for radon and mitigating any problems found.
