Résumé

Despite a widely recognised need, electronic devices for personal dosimetry of neutrons or mixed neutron-photon fields are still far less established than systems for photons alone. A large research project is in progress to evaluate different methods currently available or under development for electronic personal dosimetry in mixed neutron-photon work-places. The study includes experiments in calibration fields as well as in representative work-places of the nuclear industry. This paper describes the commercial and laboratory systems under investigation and their response characteristics, which were determined so far with measurements with reference neutron fields. These were primarily carried out at the PTB in Braunschweig, Germany, with ISO standard monoenergetic beams up to 19 MeV.
