RADIATION-PROTECTIVE CHARACTERISTICS OF A COMPOSITE BASED ON A HEAT-RESISTANT MODIFIED FRACTION OF TITANIUM HYDRIDE

The article describes the technology of obtaining a highly effective composite radiation-protective material based on titanium-coated fraction of titanium hydride and alumina cement binder. The physical and mechanical properties of the resulting composite are investigated. The results of an experimental study of the radiation-protective properties of a composite material based on a titanium-coated titanium hydride and alumina cement fraction with respect to gamma and neutron radiation are presented. Point isotopic sources of fast neutrons Pu-α-Be (neutron energy - 4.5 MeV), isotopic source of gamma radiation Cs-137 (gamma-ray energy - 0.661 MeV) and isotopic source of gamma radiation Co-60 (average energy of gamma–quanta - 1.25 MeV) are used for measurements. The paper compares the effectiveness of protection based on composite and concrete. It is shown that with the same attenuation multiplicity of neutron radiation, the thickness of the protection from a composite based on a modified fraction of titanium hydride and alumina cement will be in ~ 1.7 times less than that of concrete. The use of composite materials based on a modified fraction of titanium hydride and alumina binder will significantly simplify the technology of mounting protection, reduce its weight and size characteristics, cost and increase reliability
