Title:
COMPOSITIONS OF HIGH SPECIFIC ACTIVITY SN-117M AND METHODS OF PREPARING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/074983
Kind Code:
A3
Abstract:
Compositions of high specific activity 117mSn with specific activity of greater than 100 Ci/g Sn and methods of producing the same. The method includes exposing 116Cd in a target layer (12) to an α-particle beam (16) of sufficient incident kinetic energy and duration to convert a portion of the 116Cd to 117mSn to form an irradiated material. The irradiated material in the target layer (12) is dissolved to form an intermediate solution containing117mSn and 116Cd. The 117mSn is separated from the 116Cd to yield high specific activity 117mSn.
