Radium targets for cyclotron production of 225Ac in view of targeted alpha therapy

Popis výsledku v původním jazyce

Targeted alpha therapy using the radionuclide Ac-225 has shown remarkable beneft in clinical trials to patients sufering from various cancer types. Currently most Ac-225 is produced from a few sources of Th-229 existing worldwide. However, the total amount available is only sufcient for a few thousand patient doses. Given a projected demand that is several orders of magnitude higher, alternative paths for the production of Ac-225 must be developed. We have been investigating the routenusing the Ra-226(p,2n)Ac-225 reaction. It is particularly attractive due to its large cross-section near 17 MeV proton energy and because it can be readily employed at a large number of cyclotron facilities. The excitation function of this reaction has been previously measured by us for a few energies, but discrepancies with calculations remain. Hence, new irradiation experiments are required to improve the knowledge of the excitation function to support the industrial production of Ac-225 via this route.
