Prompt gamma neutron activation analysis apparatus

Abstract

A prompt gamma neutron activation analysis (PGNAA) apparatus for measuring prompt gamma rays emitted by irradiating a material to be analyzed with neutrons according to an exemplary embodiment of the present disclosure is a PGNAA apparatus including: a case having a predetermined thickness; a neutron shield disposed inside the case and having a predetermined thickness, with a source space in which a neutron source is disposed and a target space extending on one side of the source space for inserting the target material therein; a gamma-ray measurement passage communicating with the outside by penetrating the neutron shield and the case from the target space; and a gamma meter disposed outside adjacent to the gamma-ray measurement passage to measure prompt gamma rays emitted from the target material.
