LaBr3 – Lanthanum Bromide – is a salt compound of lanthanum and bromine and one of a new generation of inorganic scintillator based gamma radiation detectors. LaBr3 scintillators have fast light output decay times provide excellent energy resolution performance.LaBr3 scintillators is the international research and application of the hottest new inorganic scintillating crystal material, with high light output, short decay time and high energy resolution excellent properties, its comprehensive performance beyond the traditional high output with platinum nai scintillation crystals, is one of the best so far found flashing performance crystal, can be widely used in nuclear medicine imaging, geological exploration, oil well logging, space physics and nuclear radiation detection field.

LaBr3 – A range of gamma spectroscopy radioisotope detection and identification systems used in the homeland security market.

LaBr3 introduces an enhanced set of capabilities to a range of gamma spectroscopy radioisotope detection and identification systems used in the homeland security market. Isotope identification utilizes several techniques (known as algorithms) which rely on the detector’s ability to discriminate peaks. The improvements in resolution allow more accurate peak discrimination in ranges where isotopes often have many overlapping peaks. This leads to better isotope classification. Screening of all types (pedestrians, cargo, conveyor belts, shipping containers, vehicles, etc.) often requires accurate isotopic identification to differentiate concerning materials from non-concerning materials (medical isotopes in patients, naturally occurring radioactive materials, etc.) Heavy R&D and deployment of instruments utilizing LaBr3 is expected in the upcoming years.
