It is shown that with the help of a mobile device based on 3He detectors and isotope sources (AmBe, PuBe, 252Cf) it is possible to detect an antipersonnel mine at a depth of up to 15 cm in dry soil and at a depth of up to 5 cm in soils with moderate water content (13.5 %). The detection radius of an antipersonnel mine, which is 5-10 cm in soils with moderate water content, has been determined. It is shown that for dry soil it is possible to use the peak of thermal neutrons 764 keV, which allows to increase the signal-background ratio up to 8 times, but is ineffective for soils with high moisture content. Mathematical models and methods for determining the stress-strain state of the winding of a closed magnetic system have been developed Proton radiology and proton computed tomography are methods developed as a variant of X-ray computed tomography and nuclear magnetic resonance techniques in the planning of proton therapy. Physical quantities important for obtaining images in proton tomography are the kinetic energy of the proton, the angle and coordinate at the exit from the surface. GEANT4 validation (version 9.6.p03) is presented to model the energy distributions of protons moving through homogeneous absorbers. Product Description popup.authors popup.nrat_date 2020-12-16 Close
