Environmental monitoring systems


ELSE NUCLEAR has been historically involved in the design and manufacturing of a broad range of products for environmental monitoring systems for a wide range of customers: nuclear power plants, regional and national environmental agencies, universities, research centres, particle accelerator facilities, etc.

Up to date, ELSE NUCLEAR has more than 3000 detection units integrated in environmental monitoring systems, installed in over 40 countries operating since the ‘90s worldwide.

Discover our complete set of products for environmental monitoring systems:

  • Ion chamber based gamma radiation monitoring unit (NAUSICAA IC-T, ICP-T, DISCOVERY IC-T)
  • Geiger Muller based gamma detectors (GM-1, MERCURY GMP WR)
  • Neutron rem counter for pulsed fields (LUPIN series)
  • Digital ratemeters (SATURN I, SATURN II)
  • Gamma and neutron environmental monitoring mobile stations (SATURN 5702)
  • Air activation monitoring systems (MISTRAL XM)
  • Environmental monitoring stations (CPMON)
  • Visualization and processing software for monitoring networks (5700 sMON)

The environmental monitoring unit LUPIN is a modular system for neutron H*(10) measurements, with excellent performance for neutron detection in pulsed fields.

The MISTRAL XM air activation monitoring system is designed to sample and monitor the gamma activity concentration resulting from air activation, in Marinelli geometry.

The MISTRAL XM Rooms is designed for free air monitoring (up to 8 sampling points), whereas the MISTRAL XM Stack is used to monitor the air expelled from a chimney or a stack.

The SATURN ratemeter is a compact acquisition and control unit, designed for managing and processing signals from the connected detector. 

SATURN 5702 is a mobile station equipped with two detectors for gamma and neutron dose rate monitoring. The station includes:

  • Ion chamber-based gamma radiation monitoring unit: ICP-T or ICP-T-PF
  • Neutron rem counter for pulsed fields: LUPIN BF3-NP

The software 5700 sMON is a complete, Windows compatible, remote software package for real time control, display and management of environmental monitoring systems, employing serial or Ethernet connections.

The CPMON monitoring station hosts an ion chamber based gamma monitoring unit NAUSICAA IC-T and/or alpha/beta air particulate monitor, as well as the electronics and the power storage batteries, linked to the solar panels installed on the top of the station.

Each station communicates with a central host PC through a radio connection.

The NAUSICAA ion chamber based gamma radiation monitoring unit is a modular system that comes in two versions: the IC-T version is equipped with a 9 decades electrometer for environmental measurements, whereas the IC-T-PF version is equipped with a 7 decades electrometer for pulsed field measurements. Both versions share the same main components: ion chamber, power supply, electrometer, acquisition and control unit.

Geiger-Müller detectors for gamma radiation detection can be provided in different versions: single Geiger detectors GM-1 and double Geiger detectors MERCURY GMP WR for extended measurement range.
