In order to detect the chemical weapon contained in the unmarked ammunition,a fast neutron chemical weapon detection system based on associatedαparticle technology(APT)was developed.The detection system included an associated particle DT neutron source,anαparticle detector,aγdetector and shielding as well as an electronics signal acquiring and processing system.Four types of chemical weapons including sarin,VX reagent,mustard gas and adamsite reagent were measured by the detection system.The characteristic ...
