Nonlinear Correction Methods of Temperature-Caused Peak Shift for a NaI(Tl) Gamma-Ray Spectrometer

Figure 4

(a) The raw measured spectra are corrected using temperature-caused peak-shift correction algorithm based on the multicharacteristic peak area weighting factor (IED_310). (b) The raw measured spectra are corrected using an interpolation correction algorithm based on multicharacteristic peak sequence (IED_310).
