ABSTRACT:
A radiation scintillation detector which is particularly suited for X-ray detection is formed as a solid body of rotation about a central axis of a scintillator medium. The body includes at least one internal reflective surface, and at least one substantially planar surface through which the light is substantially transmitted to a photomultiplier tube. The curvilinear axial cross-section of the internal reflective surface is formed such that substantially any light originating from an area in proximity to a point of most probable emission within the body and intersecting the internal reflective surface is totally reflected internally. The photomultiplier tubes will receive most of the light emitted, by virtue of the decreasing taper of each internal reflective surface as it approaches the planar surface. A detector comprising two portions, which are joined integrally back-to-back to each other, and which each include an internal reflective surface, internally reflects substantially all photons striking the reflective surface to the photomultiplier tubes.
