US Patent 11181648 Scintillator-based neutron and gamma-ray dosimeter

A method for obtaining fast neutron and gamma ray quantities in an unknown neutron and gamma ray mixed field. The method is comprised of (1) a radiation detector capable of measuring neutrons and gamma rays, (2) identification of the neutron and the gamma ray interactions based on digital pulse shape analysis, (3) formation of a pulse height (or pulse area) histogram for both neutron and gamma ray events, (4) conversion of the neutron and gamma ray pulse height (or pulse area) histogram into a quantity of interest such as count rate, energy spectra, kerma, absorbed dose, and dose equivalent, for both instantaneous and integral readings, and (5) steps (2-4) occurring in real-time.
