Comparison of Energy Resolution of NaI (Tl) Scintillation Detectors Obtained by Analog and Digital Ways

Assist. Prof. Elif Ebru Ermiş

Gamma-ray energy spectra were acquired using a Multichannel Analyzer (MCA) and a digitizer. A spectrometer which was consisted of a NaI(Tl) inorganic scintillation detector and a digitizer were used to obtain energy spectra of 137Cs radioisotope. The energy resolution values from analog and digital ways were calculated and compared with each other. The average analog and digital energy resolution values were determined as 7.69 % and 6.80 %, respectively. Obtained results showed that the digital systems are more preferable than the analog ones from the energy resolution point of view.
