1. A method for handling radioactive solutions after decontamination of the surfaces of protective equipment, the method comprising the combined evaporation of alkaline and acidic solutions containing sodium hydroxide, potassium permanganate, oxalic acid and nitric acid to a solid residue, with subsequent calcination and mixing of the calcinate with the components of the fusion mixture containing oxides of titanium, calcium, iron (III) and aluminum in certain proportions, and the combined melting of all components to produce a ceramic matrix, wherein zirconium and manganese (IV) oxides are further introduced into the mixture of the calcinate and oxides of titanium, calcium, iron (III) and aluminum in the following component proportions, wt %:Calcinate of high-level waste10.0-20.0TiO253.0-57. CaO 9.0-11.0Fe2O34.5-5.5Al2O34.5-5.5ZrO24.5-5.5and the total content of MnO2 in the mixture does not exceed 10 wt %. 2. The method of claim 1, wherein the solid residue resulting from the evaporation of decontaminating solutions is calcined at 750 to 800° C. to fully decompose nitrates and carbonates. 3. The method of claim 1, wherein the calcinate is fused at 1,350° C. or higher for 1 hour to produce a monolithic fused ceramic material.
