Patent ID: 8440980

Claim:
A method of radiation detection, comprising: providing a detection system comprising: a scintillator comprising Cs 2 LiLn Halide composition, wherein Ln is selected from one or more of Y, La, Ce, Gd, Lu and Sc, wherein the Halide comprises at least Cl; and a detection assembly coupled to the scintillator to detect a light pulse luminescence from the scintillator as a measure of a scintillation event; and positioning the system such that a radiation source is within a field of view of the system so as to detect emissions from the source; measuring a scintillation event luminescence signal from the scintillator with the detection assembly; and processing the measured luminescence signal using pulse shape discrimination analysis over a time of greater than 50 ns to differentiate between gamma emissions and neutron emissions from the source.
