Abstract: A radiation image sensor comprises (1) an image sensor 1 having a plurality of light receiving elements arranged one or two dimensionally, (2) scintillator 2 having columnar structure formed on the light-receiving surface of this image sensor 1 to convert radiation into light including wavelengths that can be detected by the image sensor 1, (3) a protective film 3 formed so as to cover and adhere to the columnar structure of the scintillator 2, and (4) a radiation-transmittable reflective plate 4 that has a reflective surface 42 disposed to face the image sensor across the protective film 3.

Abstract: An Ag film as a light-reflecting film is formed on one surface of an a-C substrate of a scintillator panel. The entire surface of the Ag film is covered with an SiN film for protecting the Ag film. A scintillator having a columnar structure, which converts an incident radiation into visible light, is formed on the surface of the SiN film. The scintillator is covered with a polyparaxylylene film together with the substrate.

Abstract: Comprising a first step of supporting a substrate formed with a scintillator on at least three protrusions of a target-support element disposed on a vapor deposition table so as to keep a distance from said vapor deposition table; a second step of introducing said vapor deposition table having said substrate supported by said target-support element into a vapor deposition chamber of a CVD apparatus; and a third step of depositing an organic film by CVD method onto all surfaces of said substrate, provided with said scintillator, introduced into said vapor deposition chamber.

Abstract: A scintillator panel 1 uses a glass substrate 5, having heat resistance, as a base member for forming a scintillator 10. Glass substrate 5 also functions as a radiation entry window. Also, a dielectric multilayer film mirror 6 is disposed as a light-reflecting film between the scintillator 10 and the glass substrate 5. Furthermore, a light-absorbing film 7 is disposed on the radiation entry surface of glass substrate 5 and this absorbs the light that has been emitted from scintillator 10 and has passed through the dielectric multilayer film mirror 6 and the glass substrate 5. Light components that are reflected by the radiation entry surface, etc., and return to the dielectric multilayer film mirror 7 and the scintillator 10 therefore do not occur and the optical output of the scintillator panel 1 is not subject to degrading effects.

Abstract: A radiation detection device comprising: a light receiving device array (6) formed by disposing two-dimensionally light receiving elements (2) on a substrate (1), arranging bonding pads (4) on the outer periphery of the substrate (1) and electrically connecting them to light receiving elements ( 2) of each row or column with signal lines (3) and depositing a protective passivation film (5) on the light receiving elements (2) and on the signal lines (3); a scintillator (7) of a CsI columnar crystal deposited on the lig ht receiving surface of the light receiving device array (6); and a protective film (11) formed by sandwiching an Al inorganic film (9) with Parillen organ ic films (8 and 10) and laminating it on the scintillator (7). The outer periphery of the protective film (11) is cut at such a position at which the bonding pads (4) are exposed, and is bonded closely to the passivation film (5) by a covering resin (12).

Abstract: A surface of a substrate made of Al in a scintillator panel 1 is sandblasted, whereas one surface thereof is formed with an MgF 2 film as a low refractive index material. The surface of MgF 2 film is formed with a scintillator having a columnar structure for converting incident radiation into visible light. Together with the substrate, the scintillator is covered with a polyparaxylylene film.
