Abstract: The present invention provides an intracellular radiation microdosimetric detection structure and detection method, and relates to the field of radiation microdosimetric detection technologies. The detection structure includes a first semiconductor detector unit, a first pixel array detector, a cellular microfluidic chip, a second pixel array detector, and a second semiconductor detector unit that are sequentially arranged in layers. The cellular microfluidic chip is configured for cell fixation and culture. The first semiconductor detector unit and the second semiconductor detector unit form a charged particle energy information detector combination for detecting deposit energy of charged particles in a semiconductor detector. The first pixel array detector and the second pixel array detector form a charged particle flux and position information detector combination for measuring a flux and an angle of charged particles incident at a position of the cellular microfluidic chip.

Abstract: The present disclosure belongs to the technical field of neutron detection, and it relates to a structure for slow neutron detection and a method for energy spectrum measurement of slow neutrons, wherein the structure for slow neutron detection comprises: a shielding barrel, which is configured as square with an opening; and a detector unit, which is a slow neutron detector with position resolution function, wherein the detector unit is completely wrapped in the shielding barrel, and the detector unit is placed close to one of the sides of the shielding barrel that is perpendicular to the open side of the shielding barrel. When the structure for slow neutron detection moves at a set speed, the incident energy spectrum of slow neutrons can be inversely extrapolated on the basis of the number of slow neutrons at different depths.
