The matrix which embeds the source is an array of ZnSe crystals, where enriched $^{82}$Se is used as decay isotope. The radiopurity of the initial components employed for manufacturing crystals, that can be operated as bolometers, is crucial for achieving a null background level in the region of interest for double-beta decay investigations. In this work, we evaluated the radioactive content in 2.5 kg of 96.3\\% enriched $^{82}$Se metal","authors_text":"A. Giuliani, C. Gotti, C. Nones, C. Rusconi, C. Tomei, D. Chiesa, E. Previtali, F.
