Tritium measurements in desiccant and pump oil

[jr_johnson@ccmail.pnl.gov (John R Johnson)]

     I agree with Franz. It is impossible to use a LSC to estimate the 
     tritium conc. without calibrating the system for the mixture used. 
     Quench can be a major factor. Anybody that has tried to and blood to a 
     cocktail knows that the efficiency goes to zero with very little added 
     blood. I would never accept LSC results without spiked sample for 
     calibration. I don't think quench measurements are good enough.
