Efficiency and resolution of HPGe and NaI(Tl) detectors using gamma-ray spectroscopy

Synthesis and characterization of 159 Gd-doped hydroxyapatite nanorods for bioapplications as theranostic systems

“…In order to investigate the phosphorous activation, 31 P(n,g) 32 P, beta spectroscopy measurements in HA sample were performed in a beta counter (Thermo Eberline HandECount, Thermo Electron Corporation, USA). To analyze the gadolinium activation, 158 Gd(n,g) 159 Gd, the gamma spectrum of the irradiated HA-Gd2.8 was obtained using a HP-Ge detector with nominal efficiency of 50% and the Canberra Genie 2000 software [34].…”

A Study of Shielding Properties of X-ray and Gamma in Barium Compounds

“…Some of the earlier work-ers measured the mass attenuation coefficient of photons using alternate to transmission experiments [9,10]. The high-purity Germanium spectrometers having poor efficiency but high resolution, NaI scintillation detectors have a poor energy resolution but high efficiency [11]. For intensity measurements, efficiency of the detector should be high rather than resolution.…”

Determination of Natural Radioactivity and Radiological Hazards of 226Ra, 232Th, and 40K in the Grains Available at Penang Markets, Malaysia, Using High-purity Germanium Detector

“…Am, and 226 Ra, that is in agreement with the study of Hossain et al, 2012. Certified standards of known activities were used to derive the calibration curve for energy and the efficiency of the HPGe detector since the efficiency is an important parameter of HPGe detector (Khandaker, 2011).…”
