Abstract: A method of isolating 99Mo produced using a (n,?) reaction according to example embodiments may include vaporizing a source compound containing 98Mo and 99Mo. The vaporized source compound may be ionized to form ions containing 98Mo and 99Mo. The ions may be separated to isolate the ions containing 99Mo. The isolated ions containing 99Mo may be collected with a collector. Accordingly, the isolated 99Mo may have a relatively high specific radioactivity and, in turn, may be used to produce the diagnostic radioisotope, 99mTc, through radioactive decay.

Abstract: A method of isolating a radioisotope according to example embodiments may include vaporizing a source compound containing a first isotope and a second isotope of an element, wherein the second isotope may have at least one of therapeutic and diagnostic properties when used as a radiopharmaceutical. The vaporized source compound may be ionized to form charged particles of the first and second isotopes. The charged particles may be separated to isolate the particles of the second isotope. The isolated charged particles of the second isotope may be collected with an oppositely-charged collector. Accordingly, the isolated second isotope may be used to produce therapeutic and/or diagnostic radiopharmaceuticals having higher specific activity.

Abstract: A method of isolating 186Re according to example embodiments may include vaporizing a source compound containing 185Re and 186Re. The vaporized source compound may be ionized to form negatively-charged molecules containing 185Re and 186Re. The negatively-charged molecules may be separated to isolate the negatively-charged molecules containing 186Re. The isolated negatively-charged molecules containing 186Re may be collected with a positively-charged collector. Accordingly, the isolated 186Re may be used to produce therapeutic and/or diagnostic radiopharmaceuticals having higher specific activity.
