Claims
- 1. A physiologically acceptable aqueous solution of tantalum-178 comprising from about 0.1 to 200 millicuries per milliliter of tantalum-178 solution.
- 2. The process for obtaining a physiologically acceptable aqueous solution of tantalum-178 which comprises binding tungsten-178 to an anion-exchange resin from a hydrochloric acid-solution containing hydrogen peroxide whereby tantalum-178 is formed in situ from said tungsten-178, eluting said tantalum-178 from said resin with an aqueous HCl solution containing hydrogen peroxide and neutralizing the aqueous HCl solution containing tantalum-178.
- 3. The process of claim 2 wherein said tungsten-178 is obtained by exposing tantalum-181 to incident proton energy of between about 32 MeV and 40 MeV.
- 4. The process of claim 3 wherein said proton energy is 34 MeV.
- 5. A kit for the preparation of a physiologically acceptable solution of tantalum-178 from a resin column containing bound tungsten-178 which comprises a first container having a volume of about 1 to 3 ml in which is aseptically and hermatically sealed a 0.05 to 0.25N HCl solution containing from about 0.05 and 3 volume percent of hydrogen peroxide and a second container having a volume of about 0.5 to 3 ml and in which is sealed a neutralizing agent for said acidic solution.
- 6. The kit of claim 5 wherein the second container is partially evacuated.
- 7. The kit of claim 6 wherein the second container is provided with a hypodermic syringe.
- 8. The kit of claim 6 wherein said neutralizing agent is sodium bisulfite.
