State Indoor Radon Grant (SIRG) Program

On this page:


State and tribal radon programs are critical to the Agency's national goal of minimizing and preventing radon-related lung cancer. States and tribes receive grant funds from EPA that help finance their radon risk reduction programs; recipients must provide a minimum of 40% in matching funds. By law, these State Indoor Radon Grant (SIRG) funds are not available to individuals or homeowners.

Those receiving SIRG funds must:

  1. Align their projects and activities with the Agency's strategic goals
  2. Demonstrate, capture and report results

In alignment with EPA’s FY2018-2022 Strategic Goals, the Agency’s radon program’s principle objectives are to:

  • Build new homes with radon-reducing features where appropriate, by encouraging home builders to voluntarily include these features, and by local governments adopting building codes that require these features;
  • Have existing homes tested and fixed by homeowners when appropriate, and especially by home sellers and buyers during residential real estate transfers;
  • Build new schools with radon-reducing features where appropriate, and to have existing schools tested and fixed when necessary; and
  • Conduct projects and activities that directly support the first three strategic goals (above), including promoting action by:
    • consumers
    • real estate professionals
    • state and local building code officials
    • schools officials
    • non-profit public health organizations
    • professional organizations
    • partnerships
