摘要：

The diffuse reflection spectra (in the range of 300-1000 nm) of polypropylene modified with aluminum-oxide nanoparticles in the concentration range of 1-5 wt %, its integrated absorption coefficient of solar radiation, as well as their change after electron irradiation (E = 30 keV, Phi = 2 x 10(16) cm(-2)) are studied. The optimal concentration of nanoparticles (2 wt %), at which the radiation resistance increases by 9.5 times, is established. The results of this study can be used for the selection of materials that work under the influence of ionizing radiation in outer space, in nuclear power plants, and in accelerator and X-ray facilities.
