A system and method are provided for reclaiming an enriched radioisotope starting material (14) from a target body (12). The system and method enable reclaiming the starting material in a relatively short time (e.g., several hours) after the target body's bombardment with energetic particles, greatly simplifying the target body's chemical processing, as well as reducing the cost of such processing (e.g., reducing the need for costly long-term storage). Specifically, a chemical protective layer (16) is disposed between a radioisotope starting material (14) and a base material (18) of the target body (12). After the target body is irradiated with a suitable source (e.g., particle accelerator), then the irradiated radioisotope starting material and be removed without removing the base material due to the protection provided by the chemical protective layer. The system and method also enable the operator to obtain three different radioisotopes in a single bombardment of the target body, further reducing cost of radioisotope production.

La présente invention concerne un système et un procédé destinés à récupérer une matière de départ radio-isotopique (14) enrichie à partir d'un corps cible (12). Le système et le procédé permettent la récupération de ladite matière en relativement peu de temps (par exemple, plusieurs heures) après le bombardement du corps cible avec des particules énergétiques, ce qui simplifie grandement le traitement chimique du corps cible, et réduit également le coût d'un tel traitement (par exemple, la réduction du besoin d'un stockage à long terme onéreux). En particulier, une couche protectrice chimique (16) est disposée entre une matière de départ radio-isotopique (14) et un matériau de base (18) du corps cible (12). Après irradiation du corps cible avec une source adaptée (par exemple, un accélérateur de particules), ledit matériau irradié peut être retiré sans retirer le matériau de base en raison de la protection formée par la couche protectrice chimique. Le système et le procédé permettent également que l'opérateur obtienne trois radio-isotopes différents en un seul bombardement du corps cible, réduisant encore le coût de la production radio-isotopique.
