摘要：
A 891 g BGO (Bi4Ge3O12) scintillating bolometer has been tested at 10 mK in the underground Laboratori Nazionali del Gran Sasso (Italy). The discrimination capability, the radio-purity of the compound and the main features of the crystal have been studied in order to demonstrate the excellent performances obtained by operating a scintillating bolometer in the field of gamma and alpha spectroscopy. The sensitivity of this detector in the study of extremely low surface contaminations has been investigated.
