In response to the Helium 3 shortage, RMD developed CLYC (Cs2LiYCl6:Ce) scintillation crystals consisting of Cesium, Lithium, Yttrium, and Chlorine, doped with Cerium and with the Lithium enriched in 6 Li. When utilized in a radiation detector, CLYC gives first responders the ability to identify the presence and type of nuclear radiation.
