Abstract: A portable hand-held system for identification of a radiation source includes a portable detection unit that detects gamma radiation, X-ray radiation and neutron radiation emitted due to nuclear decay in the radiation source being inspected and provides a corresponding detection signal based on the radiation. A radioisotope analysis unit analyzes radiation detected by the detection unit for determining radioisotope information. A display unit for displaying results of the analysis to a user, including radiation spectrum and the radioisotope information. A GPS receiver provides a current position information. A connecting unit communicates the results of the analysis and the current location to a remote computer. The detection unit, the radioisotope analysis unit, the display unit, the GPS receiver and the connecting unit form an integral device. The common housing includes a personal communicator with a microprocessor for the analyzing of the radiation spectra.

Abstract: A multipurpose, small-sized, ergonomic device determines and measures ionizing radiation and stores the obtained data for subsequent processing. An ionizing radiation detector is used as a sensing unit and is connected with a microcontroller by a converter. The device contains a nonvolatile memory for data arrangement and command set and an interface for connection with a computer. Measurements are carried out constantly, records are made periodically by the user setting. In the case of a value current or accumulated established criterion level excess, the device gives an alert signal and stores current value, not waiting for periodic write time. At connection with a computer, these data are automatically transferred to the computer and processed for identification and saving.

Abstract: The invention belongs to the field of remote object identification by its passive and/or active radiation, namely, the systems allowing to identify objects including the concealed ones. The goal of the invention under consideration is to develop a mobile and yet highly-efficient object detection and identification system by gamma, X-ray and neutron radiation. Besides, the other objective of the proposed invention is to make it possible to create a distributed multilevel system for a departmental use as well as an open system for common use. The problem put by is solved as follows: 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 realized; and the next level represents the global specialized expert system performance in real time.

Abstract: The invention belongs to systems of identification of remote objects by detecting gamma, X-ray and neutron radiations, particularly, to systems allowing to identify objects that are concealed or forbidden to transfer, for example, at customs, checkpoints etc. The task of the present invention is to create mobile and simultaneously high capacity objects monitoring and identification system. Moreover, invention task is to make it possible to develop distributed multilevel system, as for departmental usage, and open system for common usage. The set problem is solved by that the detection unit is made separately with a micro controller and data transfer device, the preprocessing unit is supplied with a channel for data acquisition from detection unit, and processor, and display unit and two-way channel of communication with object identification expert system.

Abstract: The invention relates to combined individual devices which combine timekeeping functions with monitoring of the radiation dosage to which the user is exposed and of radiation intensity. The aim of current invention is to use Geiger-Muller counter as a radiation detector in individual wristwatch and to ensure its functioning over a long period of time. A voltage changer able to change tension from 1.5V-3V to 400V is needed to make the Geiger-Muller counter function in wristwatch and other compact devices. This was realized by installing in the certain wristwatch a Geiger-Muller counter functioning as a radiation detector and a voltage pulse converter for GeigerMuller counter power supply; and the micro controller was connected to the voltage changer.
