Gamma Ray Spectrometry : Analyzing the Response of a Gamma Ray Spectrometer

Abstract

We experimentally analyzed the internal components of an old gamma ray spectrometer. The NaI(TI) spectrometer was manufactured in 1979 and all of its internal components are original. We were unable to open the device to examine its internal components without destroying the detector. Therefore, we determined the state of the scintillator through indirect means and found that there was no evidence of cracks or impurities in the NaI(Tl) crystal. Knowing the detector is free of internal defects will allow future use of the detector without concern about its reliability.
