Energy resolution improvement of NaI(Tl) scintillation detectors by means of a timing discrimination method
- 471 Downloads
Gamma-ray energy spectrum of a 137Cs radioisotope was obtained by using a NaI(Tl) scintillation detector. Improvement of the energy resolution of the detector was aimed. To achieve this, constant fraction timing method was used. Energy resolution of the photopeak of the isotope was improved from 7.1 to 6.7% through the timing application.
