Hello,

Does anyone know of a commercial provider who can determine the 
sensitivity of NaI (or other) gamma count rate meters using extended 
sources, e.g. uranium-bearing (and/or Th or K) pads?  We had 
previously used a laboratory that provides sensitivity in cps per 
uR/h for U, Th and K for such meters, but the lab will no longer be 
providing this service.  Because of the non-linear energy response of 
some survey meters,  this is useful for meters intended for radiation 
surveys of tailings, waste areas, etc. containing above-background 
concentrations of U, Th or K.
