Radiation detector comprises fluorescent parts, an intermediate area, and a separating part which reflects and/or is opaque to the light

摘要

Radiation detector (1) comprises at least two fluorescent parts (11), an intermediate area between them, and a separating part which reflects and/or is opaque to the light. The separating part and the fluorescent part are spaced apart, and the medium between them has a refractive index which is smaller than that of the fluorescent material.
