Description
Electronic personal dosemeters (EPDs) are widely used for operational radiation protection in large-scale facilities such as nuclear power plants and particle accelerators. While EPDs for photon radiation are well established and generally comply with relevant standards, neutron EPDs remain scarce. Those that do exist often exhibit strong energy and angular dependences, limiting their use without prior, field-specific information. INFN Frascati has patented an innovative EPD capable of measuring both neutron and photon radiation. The device features an almost isotropic response and, compared with commercial instruments, offers significantly higher sensitivity. Moreover, its multi-detector architecture enables the selection of an appropriate calibration factor according to the energy distribution of the incident field. This communication presents the instrument and discusses its performance in mono-energetic neutron fields as well as in representative workplace environments.
