Since the photons in the NaI detector had energies up to 1500 keV, and the GM detector has a lower threshold of ~ 100 keV, it seems like it should be possible to obtain a strong correlation between the signals from the two detectors. One thing that I did not understand was how the detected photons in the NaI detector were shown to be sourced at the live tube. There was no evident correlation between the temperature of the active side and the photon signal. Eric
