Datasheet – ANV S2 Ships and Submarines

Naval Vessel Radiation Monitoring System ANV S2
The ANV S2 is an exceptionally robust, highly qualified, naval vessel installed gamma radiation monitoring system used by navies worldwide to detect the residual radiation resulting from a nuclear weapon detonation. The system monitors the radiological environment within the ship or submarine whilst providing continuous data regarding the external threat in both air and water. The ANV S2 design has been proven in a comprehensive range of environmental and other conditions against UK MOD Defense Standards.

The system’s modules are designed to:

  • perform continuously with minimum maintenance.
  • have excellent reliability.


An ANV S2 system can have up to seven detectors capable of measuring from natural background to full threat levels which may be experienced post nuclear weapon detonation. The detectors are sited to monitor the exposure of the crew, the airborne threat and sea water contamination. For smaller vessels and submarines, a two detector system is used providing the same comprehensive data, alarms and displays for the platform.
