Scintillative rays conversion screen and process for the manufacture of the same.

摘要

1. Method of fabricating a scintillation material layer for a radiation conversion scintillation screen, receiving the X or gamma rays and converting them into light photons, this scintillation material layer (2) being obtained by evaporation on a carrier formed of a material having a thermal expansion coefficient different from that of the scintillation material (2), characterized in that the evaporation is performed on the perfectly smooth convex face of the carrier and in that, after evaporation, the scintillation material layer (2) is separated from the carrier simply by heating.
