Analysis on Gamma Spectra by NaI (Tl) Detector Shin Thant Lwan Maung Kay Khaing Oo The (3'' x 3'') NaI (Tl) detector at the Experimental Nuclear Laboratory, Physics Department, Mandalay University was used for gamma spectrum analysis incorporation with Gamma Vision 32 software. The standard gamma source 152Eu (Spectrum Technique, USA) was used to calibrate the NaI (Tl) detector. Calibration range was 122 keV to 1408 keV and showed a linear relation of 0.943 keV per channel. Sand sample from Moemauk Hot Spring, Banmaw Township, Kachin State was analyzed by gamma spectroscopy. The gamma emissions were observed at 212Pb (239 keV), 228Ac (338 keV), 208Tl (583 keV), 228Ac (911 keV) and 40K (1460 keV). With high resolution detector, such as HpGe, more gamma emissions were expected to be observed. 2018-11-27 http://hdl.handle.net/20.500.12678/0000005162 https://meral.edu.mm/records/5162
