Abstract:
     This invention is used in neutron photograph. According to this invention, concentrated 6LiF is used as reaction material and ZnS (Ag) as fluorescent material. This intensifying screen characterized by long persistance, 7 micrometers of central granularity, macromolecule polymer EvA as binder and 6LiF: ZnS (Ag): EvA=1:4.5:1.25. The mixed materials are smelted at 130-200 deg.C and mixed unifomly. The through pressing with mould, a screen is obtained, whose main properties such as inherent resolution and relative blackness are superior to those of NE 426 screen made in England.
