NaI Scintillator Sources
NaI Scintillator Sources
The most expedient approach for assembling a NaI detector would be to grab an assembled scintillator/PMT from some place like Ebay. They regularly pop up there. Don Orie at Oetech might have some finished assemblies as well. If you really have a yen to assemble a scintillator by your lonesome, a canned crystal is probably the best approach. This is a crystal in an aluminum can with reflective packing and a glass window for PMT interface. I have also seen canned crystals from both the above mentioned sources. "Special scintillator" radiation counters can also be disassembled for their scintillator assemblies.
