Argon Electronics LLP is a world leader in the design and manufacture of CBRN (Chemical, Biological, Radiological, Nuclear) and Hazardous material training simulators. The function and appearance of radiation dosimeters, detectors and spectrometers and their response to radiological hazards is accurately simulated. A common simulation technology base enables the safe and realistic use of multiple simulator types. The new PlumeSIM classroom and wide-area collective field training systems enable remote instructor management of simulator instruments under fully configurable ‘virtual plumes’ or ‘hotspots’ in real time over user selected mapping.
