Patent number: 8058624Abstract: A simple method is developed for detection of fast neutrons for systems of detection of radioactive materials, which does not involve moderator systems, operates on the real time scale and ensures high detection efficiency. The method includes conversion of the cascade of gamma-quanta formed as a result of inelastic scattering of neutrons in a converter material with high atomic number into a set of light scintillations by a scintillator, processing of signals obtained in recording of said scintillations, formation of counting pulses with frequency proportional to the neutron flux and their recording according to an appropriate algorithm. Inorganic scintillators with high effective atomic number are used, and, as converter materials for inelastic scattering of neutrons, materials with high atomic numbers are used, which are a constituent part of said inorganic scintillators.Type: GrantFiled: May 4, 2009Date of Patent: November 15, 2011Assignee: Institute of Scintillation Materials, National Academy of Sciences of UkraineInventors: Boris Viktorovich Grynyov, Volodymyr Diomydovych Ryzhikov, Liudmyla Lavrentiivna Nagorna, Genadiy Mychaylovich Onishenko, Leonid Oleksiyvich Piven

Patent number: 7912177Abstract: An efficient X-ray radiographic method for recognition of materials of inspected objects and a corresponding device with improved functional possibilities are proposed, ensuring direct determination of the effective atomic number Zeff of the material, its density and thickness, as well as chemical composition. In customs inspection this should ensure practically unambiguous identification of explosives and drugs, and in medical tomography—early diagnostics of cancer tumors, osteoporosis, atherosclerosis and other dangerous and widespread diseases. The method includes X-raying of the inspected objects and recording of the transmitted radiation in several different spectral ranges with different effective energy by multi-element radiation receivers.Type: GrantFiled: August 12, 2009Date of Patent: March 22, 2011Assignee: Institute of Scintillation Materials, National Academy of Sciences of UkraineInventors: Sergei Vyacheslavovich Naydenov, Boris Viktorovich Grynyov, Volodymyr Diomydovych Ryzhikov
