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

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 PAs budget issues.
• State Agencies Reluctant to commit to
  participation due to uncertainty over budget and
  staffing.

Sources of Information on Large Scale Cs-137
Contamination Event

• Chernobyl 1986
• Goiania, Brazil - 1987
