1. A method of radiation detection, comprising:
providing a detection system including a scintillator material and a detector assembly coupled to the scintillator material and configured to detect a light pulse luminescence from the scintillator material as a measure of a scintillation event, wherein the scintillator material comprises a thallium-based halide composition, wherein the thallium-based halide composition has the general formula of Tl2LiYCl6;
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; and
measuring a scintillation event luminescence signal from the scintillator with the detection assembly,
wherein the source emits gamma-rays and neutrons and the method further comprises differentiating gamma-ray detection and neutron detection using pulse shape discrimination (PSD) analysis.
