Radiation measurement installation

摘要

In an exemplary embodiment, a radiation source emits a fan-shaped beam of rays, and a radiation receiver has a row of photoelectric transducers. Before each photoelectric transducer at least three like scintillation crystals are arranged in the row which are separated from one another by thin, opaque layers. Between each photoelectric transducer and the associated scintillation crystals, a medium is arranged which has a light transmission decreasing from the center of the respective photoelectric transducer in the direction of the outer edges of said transducer.
