Abstract
A terminally sterilized isotope generator for producing an alpha-emitting Lead-212 (Pb) daughter isotope by emanation of Radon-220 (Rn) gas from Radium-224, comprising a closed retainer assembly including a parent-isotope chamber for receiving a parent isotope, a daughter-isotope chamber for collecting thePb daughter isotope, and a gas permeable membrane separating the parent-isotope chamber from the daughter-isotope chamber, wherein the parent isotope is naturally decaying intoRn within the parent-isotope chamber, wherein the gas permeable membrane allows theRn to passively pass therethrough, wherein theRn is spontaneously decaying intoPb within the daughter-isotope chamber. An eluent is delivered in the daughter-isotope chamber, to elute in a liquid form thePb generated in a gaseous form; and a collection container collects thePb daughter-isotope eluted. The isotope generator is scalable based on requiredPb daughter-isotope quantities to be generated, thePb daughter-isotope quantities ranging from 1 mCi to 500 mCi.
