• Non-destructive assay
• Neutron and gamma ray transmission
• Cf-252 source

A new laboratory facility for non-destructive analysis (NDA) using a time-tagged Cf-252 source is presented. The system is designed to analyze samples having maximum size of about 20 x 25 cm(2), the material recognition being obtained by measuring simultaneously total and energy dependent transmission of neutrons and gamma rays. The equipment technical characteristics and performances of the NDA system are presented, exploring also limits due to the sample thickness. Some recent applications in the field of cultural heritage are presented.
