Investigation of Nanostructured Radiation-protective Composites

AbstractThere were studied mechanisms of radiation dispersion using nanoparticles, which increase effective path of radiation quantum in nanocomposites, and which increase neutron- and Roentgen rays-protective properties multiplying of mitigation by the composite and optimal sizes of nanocrystals and filler nanoparticles were calculated. The performed experimental studies to define absorbing capability of the composite materials with fillers of tungsten and lead oxides nanocrystalline powders shown, that application of these filler materials for radiation-protective materials allows increase efficiency of radiation protection for 1.34-1.43 times in comparison to analogue material with coarse crystalines
