Ingestion Pathway Exercise Scenarios Developing Field Data and GIS Maps

This document outlines the development of ingestion pathway exercise scenarios to enhance radiation protection and emergency management strategies in Wisconsin. Experts Dr. Perry Manor, Lisa Olson-McDonald, and Paul Schmidt collaborated to create actionable strategies for plume release, field monitoring, and agricultural management in response to radioactive contamination. Key activities include local, state, and federal coordination, plume projection modeling, and ingestion sampling strategies. The document highlights the importance of clear communication and preparation for various scenarios to mitigate risks effectively.

Counties) Return Release terminates

  3. Scenario Pitfalls • Disconnect between plume phase and ingestion phase objectives • Transition between plume and ingestion phase • Relocation

  4. Pitfall 1: Disconnect between plume and ingestion phase objectives • Ignore all data beyond 50 miles • Two source terms • Rain out • Smaller source on Day 1 • Develop Day 1 and 2 data and maps internally with same software

  5. Pitfall 2: Transition between plume phase and ingestion phase • Gap Model • Time jump between phases • Continuous play model • No time jump between phases

  6. Pitfall 3: Relocation Options for driving relocation decision-making • Arbitrary hotspot • DRL • 230 µR/hr

  7. Three Rules of Scenario Development • Do NOT set the players up to fail!! • Scenario data may not need to be 100% accurate to adequately drive scenario play • Keep it Simple (when possible)
