Approach to Radiation Protection

 

• Environmental Monitoring - Stack and site perimeter for particulate and tritium.
  
  
• Facility Surveys - work areas, waste packaging, Mock-up, RWHF, adjacent facility areas.
  
  
• Personnel Monitoring - bioassay, whole body count, digital dosimeters, whole body scan for beta gamma (when exiting work area).
  
  
• Job Coverage and Monitoring - one HP per 4-5 workers (3 tasks simultaneously), exposure monitoring to tritium and gamma, surface monitoring.
  
  
• Release of Equipment - scan for beta-gamma (no detectable), 1,000 dpm/100 cm2 for tritium surface contamination. (may change to 10,000 dpm/100cm2).
  
  
• Radioactive Waste Characterization - smear for tritium by system and estimate surface area. Gamma survey on loaded containers for other radionuclides.
  
  
• Containment - tents for diamond wire cutting using engineered ventilation.
  
  
• Cutting - Baseline plan to cut all metals with shears except for VV. PF coils and pump ducts.
