چکیده انگلیسی
Low-energy γ-ray spectra were collected from 241Am, 57Co, 133Ba, 198Au, 137Cs and 235U using a 3.4×3.4×5.7 mm3 CdZnTe detector utilizing an insulated Frisch ring. The CdZnTe detector was fabricated from a single crystal and a copper shim was used as the Frisch collar. Room-temperature energy resolution of 1.45% full-width half-maximum (FWHM) was obtained for 137Cs at 661.7 keV without electronic correction. The detector fabrication process is described and the resulting energy spectra are discussed. The detector fabrication process is described and the resulting energy spectra are discussed. The detector full-energy-peak intrinsic efficiency is reported for different γ-ray energies, specifically from 241Am, 57Co, 133Ba and 137Cs.
