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 1 st Year PAG
14
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 (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
