A METHOD OF FORMING AN INJECTABLE RADIOACTIVE COMPOSITION OFA CARBON ENCAPSULATED RADIOACTIVE PARTICULATE

A method of forming an injectable radioactive composition, the method comprising the steps of: (a) depositing a solid form of technetium onto a carbon crucible; (b) preheating the solid form of technetium to remove any carrier; (c) plasma ablating the technetium and portions of the carbon crucible;...

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