|Abstract:||This report presents a comparison between conventional and novel neutron detection techniques in use or planned to be used at Nordic countries as well as developed by companies. The intercomparison measurements were performed at the Metrology laboratory of the Finnish Radiation and Nuclear Safety Authority using Cf-252 and Am/Be sources. The following organizations participated in the project:
- Lund University/Swedish Radiation Safety Authority
- Icelandic Radiation Safety Authority, GR
- Norwegian Radiation Protection Authority, NRPA
- Finnish Radiation and Nuclear Safety Authority, STUK
- MARS Project, Oxford University
- Arktis Radiation Detectors Ltd.
- FinPhys Oy
- Symetrica Security Ltd.
The count rates, absolute detection efficiencies and sensitivities are presented together with descriptions of the tested detectors. Maybe the most important result is the knowledge transfer between the Nordic countries in particular and the neutron detection community in general. Measurements sessions such as this are rare and the NKS NOVE project attracted international interest.
Prior to the measurements at STUK, a seminar was organized by GR in Reykjavík, Iceland. The outcome of the seminar (including field measurements) are included in an appendix to the report.|
