Abstract
The present disclosure relates to systems and methods for producing tailored solutions or medicaments containing radioactive isotopes (e.g., alpha particle emitting radioactive isotopes). The solutions may be produced by appropriate aging and separation steps. Therapeutically effective amounts of Ac-225 and/or Bi-213 may thus be obtained.
Claims10
A method comprising:
- (a) aging a starting aqueous acidic actinide element solution comprising at least one of (i) U-233 cations and (ii) Th-229 cations, wherein the aging comprises:
- (i) radioactively decaying at least one of the U-233 cations and Th-229 cations, thereby producing an aged starting aqueous acidic actinide element solution having progeny divalent cations;
- and
- (b) exposing the aged starting aqueous acidic actinide element solution to an adsorbent, thereby adsorbing, by the adsorbent, at least a portion of the progeny divalent cations of the aged starting aqueous acidic actinide element solution.
