Average Gamma Energy Calc

[trolnia@entergy.com]

     Radsafers,
     
     Does anyone have a tested method for calculation of "E bar gamma", 
     average gamma energy, from gamma spec or radiochem analysis? I have 
     reasonably good isotopic data for our PWR waste stream and need to 
     periodically prove that the calibration of certain instruments is 
     acceptable versus the average gamma energy of isotopes present in 
     waste stream gamma spec.  The practical purpose is to ensure our whole 
     body counters are calibrated to measure the actual energies 
     encountered.  Previously, I have used an energy weighted approach. Any 
     suggestions?
