| 摘要 |
A method for detecting nuclear material in an object analysed by neutron interrogation with an associated particle tube, where the method includes steps of detection of coinciding pulses by detector pixels of at least one matrix of detector pixels, where a step of detection of coinciding pulses leads to the formation of an event which reflects a fission reaction which occurs in the nuclear material, where the method includes a search for adjoining pixels amongst the pixels which have detected coinciding pulses, a grouping of adjoining pixels into groups of adjoining pixels, a count of the pixels and/or groups of adjoining pixels which have detected coinciding pulses, and a validation of the occurrence of an event provided at least three pixels and/or groups of adjoining pixels are counted. |
