Xenon detector based gamma-ray spectrometer for a radioactive waste sorting complex and its characteristics are described. It has been shown that the "thin-wall" modification of the detector allows better registration of low-energy gamma rays (tens of keV). The spectrometer is capable of operation in unfavorable field conditions and can identify ra...

... [6]. Figure . Along with a gamma-ray detector with a working volume of 2000 cm3, it is possible to manufacture devices both large (4000 cm 3 [6] or 5000 cm 3 [7]) and small volumes (200 cm 3 [8]). The choice of the working volume may depend on the assigned tasks for the robotic automated complex at DNRHF. ...
... The staff of the Radiation Laboratory of the Institute of Space Physics of the National Nuclear Research University MEPhI have extensive experience in the development of gamma spectrometers based on compressed xenon, which were used as a prototype radioactive waste sorting complex [6], a portal complex for passenger flow management [9], an automated system for monitoring the gaseous radioactive emissions of a nuclear reactor [10]. It is important to note that the HPXe spectrometers are being developed for the first time with the aim of using an automated robotic complex for DNRHF. ...
The article focuses on a robotic gamma-ray spectrometric complex designed for decommissioning nuclear and radiation-hazardous objects and monitoring radioactive waste. The complex includes various components, such as radiation monitoring and regular observations to determine the object’s radiation parameters. The control of nuclear and radiation-hazardous objects performed using a High Pressure Xenon gamma-ray spectrometer that installed on a remotely controlled platform.
The paper considers the structure of robotic gamma-spectrometric complexes for the decommissioning of nuclear facilities. It presents physical and technical characteristics of xenon gamma-ray spectrometer considered a key instrument for gamma-ray spectra measurements of analyzed objects and their activity. The study demonstrated the feasibility of xenon gamma spectrometers application in the decommissioning of nuclear facilities. Remotely received information from a gamma spectrometric complex is transmitted via Internet to a remote computer enabling realtime processing of the experimental data.
