The results of comparative experimental studies of the effect of various radiation protection (RP) fillers of composite materials based on their fosfogipsum binding properties of RP
From the analysis of results of experimental studies of the effect of various rare-earth filling of composite materials based on their binding fosfogipsum protective properties may be concluded. Barium sulfate as the RE filler plaster matrix displays technological instability in the manufacturing process of the composite since its metropolitan hydration gypsum. An introduction to the gypsum matrix of tungsten at a concentration of 50% by weight of the composite material gives it the RP largest properties, recorded at an accelerating voltage of 100 kV lead equivalent δPb = 1,20 mm. Composite material based on fosfogipsum binder incorporated therein particulate filler in the form of RP at a concentration of 30% by weight provides almost the same properties of RP with composite materials on the same basis with the RE filler in the form of tungsten at the same concentrationReferences
