11 Claims

1. A process for preparing dry Sn-117m tetraiodide comprising:

reacting a radioactive solid Sn containing Sn-117m with a solution of I₂in an organic solvent at a temperature and for a duration sufficient to result in the formation of Sn-117m tetraiodide; and

evaporating the organic solvent to leave dry Sn-117m tetraiodide.
