Title:

INTENSIFYING SCREEN FOR X-RAY DETECTOR, X-RAY DETECTOR, AND X-RAY INSPECTION DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/051165

Kind Code:

A1

Abstract:

An X-ray detector (6) of an embodiment is provided with a transmission-type fluorescence generation portion (11) provided on an incident portion (9a) of a detector body (9), and a reflection-type fluorescence generation portion (13) provided on a portion (9b) other than the incident portion (9a) of the detector body. The transmission-type fluorescence generation portion (11) and the reflection-type fluorescence generation portion (13) are each provided with an intensifying screen provided with a phosphor layer containing praseodymium-activated gadolinium oxysulfide phosphor particles, among which the percentage of particles having a particle diameter within plus or minus 30% of a median particle diameter is 45 vol% or more, and the filling percentage of which is 60 vol% or more, and/or an intensifying screen provided with a phosphor layer containing europium-activated barium chloride fluoride phosphor particles, among which the percentage of particles having a particle diameter within plus or minus 30% of a median particle diameter is 45 vol% or more, and the filling percentage of which is 45 vol% or more.
