Regional neutron monitoring device

One of the important equipment of the neutron radiation monitoring system in nuclear radiation areas is the neutron detection device, which is mainly used to monitor the neutron dose level in areas with activated neutrons. The monitoring information is converted into digital signals and uploaded to the local processing box through paired 4-core shielded cables. The regional neutron detection device communicates with the local host using RS485 protocol.
