Description

Technetium migration was investigated apatite a possible nuclear wastes conditioning materials. 99mTc was introduced into fluoroapatite by ion implantation. The analysis of implanted profile evolution under samples treatment allows to identify the migration process as a bulk diffusion. The observed Tc release is correlated to the oxidation of Tc by interaction with air at the sample surface. (orig.)
