Lanthanum Bromide (LaBr3(Ce)) are relatively new to the gamma ray spectroscopy industry in comparison to the long history of NaI(Tl) and CsI(Tl) scintillation. LaBr3(Ce) crystals have shown remarkable advantages over NaI(Tl) as early as 2001, and as reported in 2002 in the paper entitled "LaBr3:Ce Scintillators for Gamma Ray Spectroscopy", K.S. Shah, J. Glodo, M.…

Building Gamma Scintillation Detection Downhole Tools for High Temperature
Putting delicate scintillation detector crystals into a shock resistant hermetic casing, or shielding a photomultiplier tube (PMT) from background radiation all while drilling is one thing, ensuring that the tool can continue to operate in temperatures well above 165C is quite another matter. When Flashpoint first began to distribute its NaI(Tl) crystals and PMT tubes…
