Advanced Radiological Incident Operations ARIO

Target Audience/Disciplines

Any member of an organized federal, state, local, or tribal radiological/hazardous materials response team who have responsibility for responding to or managing a radiological incident. These individuals may be members of federal, state, tribal, local, and private-sector response teams. Local or tribal participants should reside within either of two Emergency Planning Zones (EPZ). The two EPZ’s are described as 1) the plume exposure pathway EPZ has a radius of about 10 miles from the reactor site, or 2) the ingestion exposure pathway EPZ has a radius of about 50 miles from the reactor site. There are over 100 commercial nuclear power reactors in the United States.

A spreadsheet of jurisdictions, broken down by FEMA Region and state, eligible to attend Radiological training courses is available here.


The Advanced Radiological Incident Operations course is a five-day course providing participants with the advanced skills necessary to safely respond to and manage incidents involving radiological hazards. Participants apply these skills in tabletop exercises based on realistic radiological incident scenarios, set within the ICS structure.

At the conclusion of this course, participants will be able to accomplish the following:

  • Identify hazards created by a release of nuclear power plant radioactivity and fallout created by a nuclear detonation.
  • Outline protective actions that must be taken for the public and other responders during an incident.
  • Apply relocation, re-entry, and return procedures relative to ingestion exposure pathways..
  • Recognize the benefits of using plume modeling for making response decisions during an incident involving radiological materials.
  • Identify selected radiation responder kits that may be used during radiological response.
  • Generate an Incident Action Plan.

As this course is being taught the RERO course will also be in session with both courses coming together in an Integrated Capstone Event (ICE). The ARIO course will focus on Emergency Operations Center (EOC) responsibilities, coordination of the field monitoring teams, data collection, and developing recommendations for protective actions whereas the RERO course will focus on 1st Responder hands-on equipment skills, and responsibilities as members of a field monitoring team during radiological Plume and Ingestion Pathway incidents.
