  1. PA State Participation in Liberty RadEx Randolph Easton PA BRP

  2. Liberty RadEx • National Tier 2 Full-Scale Radiological Dispersion Device (RDD) Exercise • Sponsored by EPA • Philadelphia, PA – April 2010 • RDD in Urban Environment • Focus on Intermediate and Recovery Phase Activities

  3. Liberty RadEx Timeframe • Most Exercises Focus on First Hours or Days of Response (Emergency Phase) • Liberty RadEx Will Focus on ‘Post-Emergency’ Phase Responsibilities and Coordination

  4. Liberty RadEx Focus • Unified Command (Fed., State, Local) • Federal Support to State and Local Authorities • NRF Exercise in Rad Assessment and Hazmat Response • Public Involvement in Response Planning and Community Recovery

  5. PA State Participation • PA Dept. of Environmental Protection • Central Office • Bureau of Radiation Protection • Southeast Regional Office (Norristown) • Radiation Protection • Emergency Response • Waste Program • Community Relations • Legal Staff

  6. PA Radiation Protection Missions • Accident Assessment • PAG Evaluation • Relocation, Food, Water • Integration with Federal Response • Technical Interface with State Decision Makers • Field Monitoring • Environmental Monitoring and Sampling • Integration with FRMAC

  7. Radiation Protection Staff • Central Office • Health Physics – 22 • Nuclear Safety – 6 • Southeast Regional Office (Norristown) • Health Physics – 15 • Southcentral and Southwest Regional Offices (Harrisburg and Pittsburgh) – 12-14 Health Physics Staff Each

  8. PA Radiation Protection Assets • Mobile Command Vehicles (R3V) • Mobile Field Response Vehicles (F-150s)

  9. PA Radiation Protection Assets • Portable Radiation Monitoring Instruments • Field Sampling Equipment • Radiation Measurements Laboratory

  10. Liberty RadEx Radiological Source • 2300 Ci of Cs-137 (Cesium Chloride) • 3000 lbs. Explosive • Wind 8 mph from 220 Degrees • Particle size 0.1 to 1000 microns

  11. Liberty RadEx Exposure Rates

  12. Liberty RadEx Relocation Area – EPA-400

  13. Liberty RadEx Relocation Area – PA 1st Year PAG

  14. Liberty RadEx RDD Relocation Area • Based on PA 1st year PAG of 500 mrem • Impacted Population – 61, 000 • Impacted Area – 5.5 miles long by 1 mile wide (300-600 city blocks) • Additional Buffer Zone needed • 2,000,000 tons waste (100,000 truck loads at 20 tons per truck) (Based on ORD waste calculation tool developed for Liberty RadEx.

  15. Liberty RadEx Agricultural Products Area of Concern - Ingestion

  16. Liberty RadEx Ground Deposition Area

  17. Exercise Issues and Challenges – Technical - PAGs • State PAGs and Federal PAGs for First Year Relocation Differ • Federal (EPA-400) – 2 rem in first year • PA State – 500 mrem in first year • Water PAGs – • DHS August 1, 2008 FR Notice - RDD and IND • 0.5 Rem Projected Dose in First Year. • New – Not used in exercise before.

  18. Exercise Issues and Challenges – Technical - Contamination • Contamination Levels • Where does one draw ‘the lines’ on contamination? • 500 mrem in First Year is about 8.3 uCi/sq. meter • 1 uCi/sq. meter = 22,000 dpm/100 sq. cm. • Contamination Migration • Contamination moves due to weathering • Relocates and concentrates

  19. Exercise Issues and Challenges – Technical - Cleanup • Contamination Levels for Cleanup: • Site Specific • One oft cited number for removable contamination is: 1000 dpm/100 sq. cm. (or about 0.05 uCi/sq. meter)

  20. Exercise Issues and Challenges – Technical – Exposure Control • Radiation Exposure Control for Workers Entering Restricted Zone • Radiation Worker – 5 rem/year • Numerous Organizations Involved in Response • Differing Dosimetry • Differing Administrative Dose Limits

  21. Exercise Issues and Challenges – Technical - PPE • Level of PPE required • Respiratory Protection • Air Sampling and Re-suspension Factor • Training and Physical • Equipment

  22. PA State Issues and Challenges - Administrative • Budget Issue – What level of funding can be approved, given PA’s budget issues. • State Agencies – Reluctant to commit to participation due to uncertainty over budget and staffing.

  23. Sources of Information on Large Scale Cs-137 Contamination Event • Chernobyl – 1986 • Goiania, Brazil - 1987
