Abstract

One general embodiment according to the present disclosure may be formation evaluation tool for detecting radiation in a borehole in a volume of an earth formation. The tool may include a detector including a monolithic scintillation element comprising a coherent assemblage of joined fibers, wherein the fibers are made of an optically transparent scintillation media. The fibers may be at least one of i) gamma ray responsive; and ii) neutron responsive. The coherent assemblage of fibers may be a continuous mass, may be heat-joined. The fibers may be solid. The scintillation media may comprise at least one of i) organic crystalline scintillation materials, ii) amorphous glass, and iii) nanostructured glass ceramics. The coherent assemblage of fibers may be asymmetric. The coherent assemblage of fibers may surround a further scintillation media having different scintillation characteristics than the scintillation media. The scintillation element may be azimuthally sensitive.
