PA State Participation in Liberty RadEx
Randolph Easton
PA BRP
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
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
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

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
Liberty RadEx Exposure Rates
Liberty RadEx Relocation Area – EPA-400
Liberty RadEx Relocation Area – PA 1st Year PAG
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.
Liberty RadEx Agricultural Products Area of Concern - Ingestion
Liberty RadEx Ground Deposition Area
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.
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
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)
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
Exercise Issues and Challenges – Technical - PPE
Level of PPE required Respiratory Protection
– Air Sampling and Re-suspension Factor– Training and Physical– Equipment
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.
