Described herein are methods and devices for infusion of a radioactive compound, such as yttrium-90 radiolabeled somatostatin peptide or analog. A radiation shield defining a shielded cavity suitable for storing a radioactive substance includes a first aperture providing external access to the shielded cavity and a second aperture suitable for transferring a dosage vial into and out of the shielded cavity. A removable shielded plug and panel are adapted to shield respective apertures of the radiation shield. At least one dose of a radio-labeled compound stored in a vial in the radiation shield is delivered through a fluid communication channel at a rate of about 500 mL/hour. The fluid communication channel is washed after delivery, such that the process substantially reduces radiation exposure during infusion of the radiolabeled compound into a patient.

Linvention concerne des procédés et dispositifs pour linfusion dun composé radioactif, tel quun peptide de somatostatine radiomarqué à lyttrium 90 ou un analogue. Un bouclier de protection définissant une cavité blindée appropriée pour stocker une substance radioactive comprend une première ouverture fournissant un accès externe à la cavité blindée et une seconde ouverture appropriée pour transférer un flacon de dosage dans et hors de la cavité blindée. Un bouchon et un panneau blindés amovibles sont adaptés pour protéger des ouvertures respectives du bouclier de protection. Au moins une dose dun composé radiomarqué stocké dans un flacon dans le bouclier de protection est délivrée à travers un canal de communication fluidique à une vitesse denviron 500 mL/heure. Le canal de communication fluidique est lavé après livraison, de telle sorte que le procédé réduise sensiblement lexposition au rayonnement pendant linfusion du composé radiomarqué dans un patient.
