A IONIZING RADIATION BEAM DETECTOR

摘要

A ionizing radiation detector comprising a plurality of scintillators (12) of plastic material, wherein said scintillators (12) are in form of co-planar plates disposed according to a two-dimensional ordered arrangement, each plate having a respective optical fiber (13) joined to a face or to a perimetral edge portion of the plate for conveying scintillation light pulses to a photodetector (20).
