中子探測-
In analyzing the neutron active detection, the neutron multiplication in the nuclear warheads induced by outer neutron source with different neutron energys is studied with numeral simulation, and the feasibility of through counting neutrons to determine the presence of high enrichment uranium ( heu ) in nuclear warhead has been proved. the method of detecting the warhead which contains heu pit by counting the released neut rons whose energy is higher than that of source neutron is studied. the feasibility of this method has been studied
