Neutron area survey instrument measurements in the EVIDOS project

Abstract

Neutron survey instruments have been exposed at all the measurement locations used in the EVIDOS project. These results have an important impact in the interpretation of the results from the project, since operationally the survey instrument will be used for an initial assessment of and routine monitoring of the ambient dose equivalent dose rate. Additionally, since the response of these instruments is in some cases very well characterised, their systematic deviations from the reference quantities provide an important verification of the determination of those quantities.

“…There is currently no reference field available for epithermal neutrons while radiation protection measuring devices show strong discrepancies in this energy range [12]. Epithermal neutron reference fields are required for the quantification and development of new devices.…”
