Scintillation and detection characteristics of high-sensitivity CeBr3 gamma-ray spectrometers

Multiple Gamma-Ray Detection Capability of a CeBr3 Detector for Gamma Spectroscopy

“…The development of the cerium tribromide (CeBr 3 ) gamma-ray detector among the lanthanum halide detector series (LaBr 3 :Ce and LaCl 3 :Ce detectors) is one such example [4][5][6][7][8][9][10][11]. The CeBr 3 detector, which has an energy resolution comparable with that of a LaCl 3 :Ce detector, has an order of magnitude reduced intrinsic activity as compared to the LaBr 3 :Ce and LaCl 3 :Ce detector [9].…”

Furthermore, the reduced intrinsic activity of the CeBr3 detector has a narrower energy range of 1400-2200 keV [9,12], as compared to 780-2200 keV energy range reported for the intrinsic activity of the LaBr 3 :Ce and LaCl 3 :Ce ( [1,3,7]).…”

These features enable the CeBr 3 detector to provide a larger interference-free energy range for the gamma-ray detection in prompt gamma-ray analysis of bulk samples as compared to the LaBr 3 :Ce and LaCl 3 :Ce detectors.…”

Development of a Cerium-Doped Lanthanum Bromide Gamma-Ray Spectrometer for Planetary Missions and Feasibility Studies for Determination of Elemental Abundances of Radioactive Elements (Th, K and U)

“…The above results indicate that LaBr 3 : Ce detectors will not be suitable for measurements of elemental abundances of Th, U and K. However, large 2  2 CeBr 3 crystals have been developed recently 6 , which provide an 6 , determination of K and Th in meteoritic and terrestrial samples is more likely to be feasible. Future measurements will determine the sensitivity of U, Th and K using CeBr 3 THE importance and dynamics of meteorological events (e.g.…”

“…There are several Iranian islands in the Persian Gulf. The most famous among them are Hormuz, Khark, Qeshm, Kish, Tonb-e-Kuchak, Tonb-e-Bozorg and AbuMusa [6][7][8][9] . In this communication, sea-level variations related to atmospheric pressure and wind fields at Bushehr and Kangan ports, Iran, which are situated in the northwestern region of the Persian Gulf, have been studied.…”
