The MDN-01 monitor is designed for the measurement of ambient dose equivalent rate Ḣ*(10) in neutron fields in different environments, such as spent fuel storage facilities in nuclear power plants, PET centres with cyclotrons, workplaces with particle accelerators, radioactive waste repositories, neutron calibration laboratories, etc.
It includes a proportional 3He detector, sensitive to low energy neutron. This detector is mounted in a moderator – a Bonner sphere made of polyethylene with a diameter of 25 cm. The moderator provides a slow-down of high-energy neutrons to neutrons of detectable energies. The measured values are compared to two adjustable alarm levels and are transferred to the host system via the RS-485 or Ethernet interface. Exceeding the alarm level will trigger an alarm.
