Abstract :
Cerium-doped lanthanum bromide, LaBr3(Ce), crystal is the latest among the scintillation counters and shows same attracting properties for γ spectroscopy that makes it a suitable solution for security, medical, geophysics and high energy physics applications. LaBr3(Ce) exhibits a proportional light yield response to γ - ray energy. Very good linearity was seen up to 2 MeV. LaBr3(Ce) has also relatively high intrinsic radiation background due to naturally occurring 138La and 227Ac radioisotopes. A good use of LaBr3(Ce) needs an accurate determination of the self-activity, particularly when low background is required or when events are collected at very low trigger rates. The impact of internal background on energy resolution and linearity is discussed.
