Thanks for the response Fred. We're trying to calibrate to 59 keV and finding that our bias and precision statistics aren't looking so hot (we have Accuscan II). We'll probably end up doing what you're doing (stopping at 88). Currently we use Co-60/Cs-137 for our check source; maybe we'll look at adding something lower energy; do you ever have any issues with your source check?

Yes we have it in the library 2. No it is not part of the mixed gamma calibration source, We calibrate down to 88 keV. we use Eu-152 as a check source. 3.

Do you include Am-241 as one of the standard nuclides in your WBC Library? 2. Is Am-241 part of your mixed gamma calibration source (do you calibrate the 59 keV energy line)? 3. What type of Whole Body Counter do you use (e.g. Canberra Fastscan, Canberra Accuscan, etc)?
