Une methode de production D'Europium 155 sans entraineur au niveau du Curie

Abstract

High activity "point" sources of Eu-155 are used for medical and industrial applications. For this purpose we have studied a method of obtaining I Ci of carrier free Eu -155, with a solid residue smaller than 5 mg per Ci. In order to separate the Eu-155 from several grams of a Sm-154 enriched target we propose a procedure which is based on the work of Bouissi&res and David, Onstott, and Takekoshi et al.The separation is carried out by electrolysis on a mercury cathode followed by purification on ion exchange resin. The yields of the europium separation and target recovery.
