摘要：
A method of forming an injectable radioactive composition, the methodcomprising the steps of: (a) depositing a solid form of technetium onto acarbon crucible； (b) preheating the solid form of technetium to remove anycarrier； (c) plasma ablating the technetium and portions of the carboncrucible； (d) allowing the carbon and technetium metal to co-condense from thegas phase to produce a nanoparticle composite aerosol in an inert gas； (e)dispersing the nanoparticle composite in water containing a low concentrationof surfactant using an electrostatic precipitator； (f) size fractionating thenanoparticle dispersion by filtration with hydrophilic membranes of known poresize.
