METHOD FOR PRODUCING RADIONUCLIDE SOURCE CORE Russian patent published in 1997 - IPC

FIELD: nuclear engineering; manufacture of actinide and lanthenide base ionizing radiation sources. SUBSTANCE: radionuclide oxide is reduced to metal, then radionuclide metal is applied to substrate by metal deposition in vacuum. Evaporation is made at evaporating cup temperature of 900-2100 C. Substrate is made of nonmetal materials, such as Si, C, Ge or nonplatinum metals, such as Cu, Ag, Au, Fe, Co, Ni. EFFECT: improved stability of compositions formed between radionuclide and substrate material; improved mechanical strength of core. 2 tbl
