This report documents the results of a study conducted to better understand the capabilities and practices of offsite response organizations (OROs) for protective actions in the intermediate phase of a radiological emergency response. The research consisted of:

  • Interviews with state OROs regarding protective action decisions (PADs) and capabilities.
  • Review of Federal Emergency Management Agency (FEMA) after action reports (AARs) from the Radiological Emergency Preparedness Program ingestion pathway exercises.
  • Review of a sample of state radiological emergency response plans.

Nine states voluntarily participated in the interview process, including at least one state from eight of the nine FEMA regions with nuclear power plants. State practices were largely consistent in several areas, including using Federal guidelines and scientific procedures to inform protective action decision-making; working within and across various levels of government to develop and implement PADs; and utilizing resources from the Federal Government or mutual aid sources as needed.

The review of AARs yielded 35 with relevant information from 25 states. This review, combined with the review of 23 state radiological emergency response plans from 21 states, augmented the interview results. Results from the interviews and the documentary reviews may be used by the Nuclear Regulatory Commission to inform modeling assumptions.
