Program Overview

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 Plan
  2. Demonstrate, capture and report results in alignment with EPA’s FY2022-2026 Strategic Plan Framework. The Agency’s long-term performance goal is to prevent 2, 250 lung cancer deaths annually through lower radon exposure as compared to the FY2020 baseline of 1,684 prevented lung cancer deaths by September 30, 2026.

In alignment with the EPA’s FY2022-2026 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
