Abstract
An isotope production system, emanation generator, and process are disclosed for production of high-purity radioisotopes. In one implementation example, high-purity Pb-212 and/or Bi-212 isotopes are produced suitable for therapeutic applications. In one embodiment the process includes transporting gaseous radon-220 from a radium-224 bearing generator which provides gas-phase separation of the Rn-220 from the Ra-224 in the generator. Subsequent decay of the captured Rn-220 accumulates high-purity Pb-212 and/or Bi-212 isotopes suitable for direct therapeutic applications. Other high-purity product isotopes may also be prepared.
Claims13
A method of producing radioisotopes, the method comprising:
- preparing a composition comprising an Ra source isotope and sorbent particles;
- loading the composition onto a solid support material to form a mixture comprising the Ra source isotope, the sorbent particles, and the solid sorbent material;
- while within the mixture, decaying at least some of the Ra source isotope to yield one or more radioactive Rn daughter isotopes in a gaseous state;
- separating the gaseous Rn daughter isotopes from the mixture;
- and
- collecting the separated Rn daughter isotopes.
