METHOD OF RADIOACTIVE OBJECT AND NUCLEAR MATERIAL IDENTIFICATION

The invention belongs to the field of remote object identification based on passive and/or active radiation, namely, to systems for to identifying radioactive objects, including concealed ones. A mobile and yet highly-efficient object detection and identification system detects gamma, X-ray and neutron radiation. A distributed multilevel system for a departmental (restricted) use, as well as an open system for common use, is proposed.The expert system is designed to be multilevel. At a low level, the capacity of the portable computer sensor of the expert system is used; at a higher level, functioning of the local network of the expert system through communication links is implemented; and the next level represents the global specialized expert system performance in real time. The transfer from a lower level to a higher level takes place in the case of radioactive object identification failure or ambiguity.
