NSN3中子仪Portable Neutron Survey Meter
The Fuji model NSN3 portable neutron survey meter is very lightweight and small without polyethylene moderator.The energy response is improved using the spectrum weighting function.
The NSN3 survey meter measures ambient dose equivalent and ambient dose equivalent rate of neutrons.
