Bent Pedersen has worked more than 25 years at the Joint Research Centre in Ispra in Italy with non–destructive assay methods and instrumentation for applications in nuclear safeguards, nuclear security and waste characterisation. He specialises in passive and active neutron detection systems for the development of characterisation, or detection, methods for fissile materials. In the laboratory, he operates a pulsed neutron interrogation facility for R&D in active neutron methods concentrating mainly on fissile materials both for safeguards and security applications. He also teaches neutron correlation techniques in both passive and active neutron counting to nuclear safeguards inspectors from Euratom and IAEA.
