Effect of 226Ra purity as a target for 225Ac production using a fast reactor
Researchers are seeking alternative 225 Ac production methods because of the scarcity of 225 Ac for targeted alpha therapy. Although 226 Ra from waste sources has been considered, obtaining 226 Ra is challenging. Therefore, the authors focused on the contamination of minerals with 232 Th-derived 228...

225
Ac production methods because of the scarcity of
225
Ac for targeted alpha therapy. Although
226
Ra from waste sources has been considered, obtaining
226
Ra is challenging. Therefore, the authors focused on the contamination of minerals with
232
Th-derived
228
Ra while investigating methods to recover
226
Ra from uranium ores. The effect of
228
Ra contamination on
225
Ac production by
226
Ra transmutation using fast reactors was evaluated. Consequently, toxic
228
Ac contaminates
225
Ac. However, using the different half-lives of
225
Ac and
228
Ac, pure
225
Ac can be obtained from the chemical separation of actinium after cooling for 5–8 days. |
