DETECTOR OF NEUTRON-AND GAMMA-RADIATIONS Russian patent published in 2004 - IPC

FIELD: for dosimetric and customs practice, for solution of the problems of the State Atom Inspection and services of nuclear safety, for complexes and systems of special radiation technical control, and radiation monitoring of territories and water areas, for detection and identification of fissionable materials.

SUBSTANCE: the detector has three transducers that are used for detection of quick, intermediate and heat neutrons, as well as for detection of gamma-radiation. The transducers are located in a common casing. PIN-sensor elements are used as transducers, they are placed in bags of boron-containing radiator-converter of neutrons made of carbide or boron nitride. The first and second transducers have inhibitors in the form of layers of hydrogen-containing material, the shape of the above inhibitors and the shape of the above radiators converters are of a variable cross-section.

EFFECT: enhanced accuracy of detection of gamma-radiation, expanded measurement range.
