CLYC is the first practical gamma-neutron scintillation detector for use as a replacement for both medium resolution gamma-ray detectors and Helium-3 proportional counter tubes for neutron detection. The ease of using Pulse Shape Discrimination (PSD) for neutron detection, combined with better gamma-ray resolution than NaI or CsI, make the CLYC detector an ideal solution for several classes of handheld instruments, including personal radiation detectors (PRDs), spectroscopic personal radiation detectors (SPRDs), and radioisotope identification devices (RIDs). Other applications requiring gamma-neutron detection can also benefit from using CLYC.
