| titleOfInvention | A method for preparing a radioactive film for application in nuclear medicine |
| abstract | The proposed process for preparing radioactive sheet for application in nuclear medicine is characterized in that metallic holmium (1) is deposited in vacuum of 10e-1 to 10e-3 Pa, preferably 10e-2 Pa to an arbitrary, thoroughly cleaned substrate, such as aluminium, polyimide, polyurethane, or paper substrate, preferably aluminium substrate for a period of 5 to 50 minutes, preferably 10 to 30 minutes. The metallic holmium layer (11), deposited onto the substrate (3) is then subjected to irradiation within a nuclear reactor for a period necessary to achieve induced radioactivity amounting to 50 to 1000 MBq. The radioactive layer (11) of the irradiated metallic holmium (1) is then covered with an overlay tape (5) preventing mechanical release of particles of the vacuum-deposited radioactive layer (11) and direct contact of that layer (11) with a patient skin during therapeutic application. Weight of the vacuum plated radioactive layer (11) ranges within 0.5 to 5 mg, preferably 1.0 to 2.5 mg and surface density thereof is in the range of 10 to 500 mg/cme2, preferably 50 to 150 mg/cme2. The sheet radioactivity ranges from several MBq units up to several hundreds up to thousand MBq units. So prepared radioactive sheet is intended for external therapy during which it is put directly onto skin tissue involved spot. |
