Portable Neutron Survey Meter Lightweight and easy to handle Excellent Gamma rejection Wide measuring range

Specification The NSN3 neutron survey meter measures the ambient dose equivalent rate. It is intended for the protection of workers in nuclear facilities and throughout the fuel cycle, research centres, particle accelerators and civil protection first response teams. The innovative detection principle of the NSN3 gas counter consists of an organic gas mixture of methane and nitrogen (neutrons are measured by this gas mixture). Fast neutrons are detected by the elastic scattering reaction of hydrogen from methane. Slow, thermal neutrons are detected by the 14N (n,p) 14C reaction of nitrogen. The...
