2 results about "Slow neutron" patented technology

The invention relates to a dosimeter (A) wearable by a human subject which includes:at least a first slow neutron sensor S1; a matrix containing a certain amount of absorbent material for slow neutrons;at least a second slow neutron sensor S2; a moderator consisting of or comprising polyethylene, hydrogenated plastic, water, paraffin or other hydrogenated or deuterated compounds.

The application discloses a deep space radiation neutron detector and belongs to the technical field of nuclear radiation detection. The gadolinium film captures slow neutrons to generate multi-state particles, the TPC module detects the three-dimensional tracks and energy of the inner conversion electrons and Auger electrons, the energy quantifier module detects the energy of the prompt gamma rays, and efficient and high-precision neutron detection is realized through electron-gamma coincidence measurement. The application adopts gadolinium to replace the scarce 3 He, solves the problems of low efficiency and high cost of the traditional detector, combines the track reconstruction capability of the TPC module and the high energy resolution of the energy quantifier, significantly improves the signal-to-noise ratio and detection sensitivity of the neutron signal, and is suitable for fields such as deep space exploration and nuclear radiation monitoring.
