Scalability study on [La]LaCl production with a focus on potential clinical applications.

Background: In recent years, targeted alpha therapy has gained importance in the clinics, and in particular, the alpha-emitter Ac plays a fundamental role in this clinical development. Nevertheless, depending on the chelating system no real diagnostic alternative has been established which shares similar chemical properties with this alpha-emitting radionuclide. In fact, the race to launch a diagnostic radionuclide to form a matched pair with Ac is still open, and La features attractive radiation properties to claim this place.
