Method and generation for generating 90 Y from 90 SR

Abstract

The present invention is related to a method for generating .sup.90 Y from .sup.90 Sr which includes steps of a) providing a crown-ether bonded silica gel, and b) having .sup.90 Sr stay with the crown-ether silica gel for a period of time. The present invention is also related to a .sup.90 Sr/.sup.90 Y generator for implementing the method, which includes a .sup.90 Sr/.sup.90 Y converting device including the crown-ether bonded silica gel for adsorbing .sup.90 Sr and converting .sup.90 Sr into .sup.90 Y, and an eluting device forcing an eluant to elute the .sup.90 Sr/.sup.90 Y converting device to obtain .sup.90 Y. The generator according to the present invention has advantages of simplicity, reusability, high yield and low cost. The obtained .sup.90 Y by the present method possesses high purity so that it is suitable for nuclear medicine use.
