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.
Claims20
An emanation system for production of ultrapure radioisotopes, comprising:
- an emanation device having an emanation source comprising a source isotope therein that emanates a radioactive gas therefrom;
- and
- a collection device configured to collect the radioactive gas retaining same for a time sufficient to yield one or more high purity radioactive daughter isotopes therein.
An emanation system for production of ultra-pure isotopes for radiotherapeutic applications, comprising:
- an emanation generator comprising a radium source configured to generate a radioactive gas that is emitted separating same therefrom;
- and
- a collection device configured to collect and retain the emitted radioactive gas for a time sufficient to decay the gas therein yielding one or more radioactive daughter isotopes therefrom.
A method of producing high purity radioisotopes, comprising the steps of:
- emanating a radioactive gas generated in a source material comprising a source isotope to separate the radioactive gas as a pure product therefrom;
- and
- collecting the separated radioactive gas and retaining same for a time sufficient to decay the radioactive gas to yield one or more high purity radioactive daughter isotopes therefrom.
