Abstract
A scintillator for radiation detection obtained by coating a light reflective material in a thickness of 50 to 150 .mu.m by a screen printing method on the surface of a solid scintillator material substrate is excellent in uniformity, dimensional accuracy with high light output. When the light reflective material layer is covered with a synthetic resin film, adhesive strength of the light reflective material layer to the substrate is increased remarkably.

A scintillator for radiation detection, including a solid scintillator material substrate adapted to have one surface thereof in contact with a light receiver, obtained by coating, by a screen printing method providing a uniform thickness of 50 to 150 .mu.m, a light reflective material on the whole surface of the solid scintillator material substrate other than the surface to be in contact with the light receiver, the light reflective material being coated on the surface of the solid scintillator material substrate as part of a mixture of said light reflective material, an organic binder and an organic solvent, and drying the light reflective material, followed by spraying and drying a synthetic resin to form a synthetic resin film on the light reflective material layer.
A scintillator for radiation detection, comprising a solid scintillator material substrate, said substrate being adapted to have a surface thereof in contact with a light receiver and all remaining surfaces coated with a light reflective layer including an organic binder and solvent, wherein the light reflective material is coated on the substrate, to form said layer, by a screen printing method, said layer having a uniform thickness of 50-150 .mu.m, whereby, for emitted light to be entered into the light receiver, a degree of parallel of 50 .mu.m or less and a light output (relative value) of at least 90 can be achieved.
