Karazin popup.description2 The methods of detection of unauthorized loads and forbidden enclosures, related to transportation of weapon, live ammunitions and fission materials, are a research object in work. The special actuality was today acquired by the problem of detection of isotopes of uranium-235 and plutonium-239 in connection with the threat of nuclear terrorism and necessity of strengthening of control above non-proliferation. Development of perceptible methods of inspection of loads, that are transported in large containers is the purpose of work, including, determination of presence of materials with a large atomic number, including fission materials on a background of masking factors. The computer simulation of reducing of bunch of brake radiation by a model is a research method and experimental researches of linked with that questions. The bunch of bremsstrahlung radiation is used from the linear electron accelerator of 6 MeV energy. Thanks to the special forming of spectrum of bremsstrahlung radiation a possibility to distinguish different materials at an identical mass thickness is created. For detecting of presence of fission materials the method of the induced fission of materials of model during the irradiation by a short neutron pulse is simultaneously developed (10-20 ns). At implementation of stage the method of obtaining 3-dimention image of contents of container with the use of one accelerator was developed. The comparative analysis of different offered in literature methods of control and developed method was executed. The previous measuring were carried out on the bremsstrahlung beam of the linear accelerator LPE-6. Data are got on dispersion and weakening of stream of brake radiation by models from different materials and background terms in a hall LPE. Development of method of discrimination of heavy metals is continued on a background the investments of other masking materials. Works are executed to reduce of radiation background of neutron generator, that is used for the active remote detecting offission materials.
