Abstract
The detector consisted of ZnS(Ag) scintillator and photomultiplier tube (PMT) is widely used ascontamination monitor in the nuclear facilities. Such detectors are mainly manufactured by adhering the ZnS(Ag)powder onto the transparent plastic. In this study the preparation condition for ZnS(Ag) scintillator sheet usinga simple method was established. The scintillator sheet was composed with a support polymer sheet and ZnS(Ag)scintillator layer. The base sheet was prepared by casting the polymer solution after solving the polymer withIt was found that the polysulfone(PSf) as a polymer for the base sheet and a cyano resin as a paste for adheringthe ZnS(Ag) scintillator was suitable. Also, the prepared thin scintillator sheet had a sufficient mechanicalstrength, a optical transparency and an alpha-ray detection performance.
