METHOD FOR FINDING NEUTRON RADIATION SOURCE Russian patent published in 2008 - IPC G01T1/169 

FIELD: technical physics, possible use for concealed detection of weak or masked sources of neutron radiation.

SUBSTANCE: method for finding neutron radiation source includes slowing neutrons by means of slower, as which operator body is used, and following registration of heat neutrons. Registration of neutron radiation is performed by means of a group of similar, time-synchronized detectors, which are moved along previously developed routes, geographic coordinates of detector positions are determined and recorded into memory together with time of registration of each neutron by each detector, on basis of results of all measurements by all detectors, density of flow of neutrons is determined in all points of examined locale, conclusion is drawn about detection of neutron radiation source, map of isolines of neutron flow density is built and by combining the map with local area plan, position of neutron radiation source is determined.

EFFECT: possible determining of position of neutron radiation source with simultaneously increased sensitivity and probability of correct detection.
