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 Relocation Area – EPA-400

Liberty RadEx Relocation Area – PA 1 st Year PAG

Liberty RadEx RDD Relocation Area Based on PA 1 st year PAG of 500 mrem Impacted Population – 61, 000 Impacted Area – 5.5 miles long by 1 mile wide ( 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.

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.
