Laminated scintillation detector capable of measuring beta energy spectrum and directional dose equivalent rate

The invention belongs to the technical field of radiation detection, and relates to a laminated scintillation detector capable of measuring beta energy spectrum and directional dose equivalent rate. The laminated scintillation detector comprises a probe. The probe comprises incident windows, a first layer of plastic scintillator, a second layer of plastic scintillator, a photomultiplier and a charge-sensitive preamplifier which are closely connected in turn. There are multiple layers of incident windows which are arranged in a staggered way and used for avoiding light and reflecting the scintillation photons generated by the plastic scintillators so as to increase the collection efficiency of the photomultiplier for the scintillation photons. The photomultiplier is used for converting thescintillation photon signals generated by the radiation particles in the plastic scintillators into electric signals. The charge-sensitive preamplifier is used for outputting the electric signals in the photomultiplier and in
