| Abstract: | Theoretical research is conducted in this paper on the causes for the spectrum-drifting of the actual operation principle,based on discussion of NaI(Tl) scintillation spectrometer system.The factors that may be the causes for the spectrum-drifting are sorted out on the grounds of energy spectrum measurements and spectrum stabilization with the result of theoretical analysis referred, so as to achieve the theoretical method of spectrum stabilization and practical techniques approach of correcting the spectrum-drifting of NaI(Tl) scintillation spectrometer. The spectrum stabilization measure is indicated on non-linearity spectrum-drifting. |

| Keywords: | NaI(Tl) scintillation spectrometer spectrum-drifting non-linearity spectrum stabilization |
