What survey methods are approved for the monthly survey?

The method depends on what radionuclide(s) your approval is approved to possess and use:

  • Approvals approved for low energy beta emitters (such as C-14, S-35 and H-3 ) must use a liquid scintillation counter.
  • Approvals approved for high energy beta emitters (such as P-32) can use a pancake probe Geiger counter.
  • Approvals approved for low energy gammas emitters (such as I-125 or Cr-51) can use a low energy gamma scintillation probe.
  • Wipes surveys with a liquid scintillation counter can substitute for portable instrument surveys.
