The Detector Efficiency (D.E.) has been calculated for both probe and well detectors. There is a difference
because the photon path length through the Nal detector is different in the two detector configurations.
There are some isotopes that the well efficiency has not been analytically determined due to gamma ray
summing in the well. You must use the empirical method for these isotopes. You may have to create a
custom version of the isotope with a different ROI to properly count the isotope in the well.
