Abstract (en)
[origin: DE19807604C1] A porous carrier for radioactive substances is made by mixing titanium dioxide, zirconium dioxide, aluminium oxide or silicon dioxide with a polysaccharide and water, followed by kneading, drying and tempering at 800-1300 deg C. Preparation of a carrier for radioactive substances comprises dry mixing of a solid carrier with a polysaccharide in a ratio of 6:4 - 9:1, followed by addition of enough water to allow kneading of the mixture. Once it has been homogenized, the mixture is dried and tempered at 800-1300 deg C to give a porous structure. An Independent claim is also included for a miniaturized radioactive source with an activity of 12-15 (preferably 20) mCi/mm<3>, which is made by soaking the carrier of the invention in a radionuclide solution, followed by tempering for a short period at 800 deg C and then at 1000-1300 deg C.
