Abstract

A scintillator for a particles is prepared by depositing by evaporation successive layers of a translucent plastic, and including in the liquid applied to form one layer a fluorescent inorganic powder; the scintillator has a total thickness of about 10 m . The scintillator may comprise, e.g. five layers of nitrocellulose, the top one containing the phosphor powder, and may also have alternate layers of a metal, e.g. aluminium, and plastic, e.g. alternately polyvinylalcohol (water soluable) and polyvinylformol chloroform soluable). The provision of alternate layers of two different plastics, soluable in different solvents and insoluable in each other's solvents, prevents dissolving a lower layer through a pin-hole in the metal layer during deposition of the next upper layer. Suitable phosphors include activated ZnS, CdS, NaI, CoI, KI, certain fluorides and calcium tungstate.
