A wide area environmental radiation monitoring network has been designed and developed by RMC in 1991.
This network includes real-time monitoring instruments installed around the nuclear power stations and major metropolitan areas for the measurements of gamma radiation.
It has the function of daily 24-hour on line continous automatic radiation monitoring in the environment. The relevant data collected are transmitted to RMC via the network.
