This paper describes a simple and practicable method for assigning energy values to gamma-ray pulse-height distributions measured with polyvinyl toluene based detectors. It is based upon the characteristic shape of the spectrum in the region of maximum energy deposition resulting from a single Compton scattering. The validity of this method is first demonstrated by applying it to a set of NaI(Tl) spectra, and comparing those results to the standard photo-peak method of calibrating the same spectra. The method is then applied to a set of polyvinyl toluene derived spectra.
