EPA's Radiation Protection program works to protect human health and the environment from harmful levels of ionizing radiation. In the Pacific Southwest Region, the program:

  • informs people about the hazards of radon gas and other forms of ionizing radiation
  • provides technical support on ionizing radiation issues to federal, state, and local government agencies
  • regulates radionuclide emissions and provides guidance on compliance with the Clean Air Act's National Emissions Standards for Hazardous Air Pollutants (NESHAP) on radionuclides
  • provides technical support for cleanup of radiation-contaminated sites
  • assists in FEMA emergency exercise evaluations about dispersal of radioactive materials
