Guardian PM500 Series is a highly sensitive walk-through, radiation portal monitor (RPM) that detects radionuclides sources as pedestrians pass through its gateway with their parcels and bags. It offers exceptional NORM discrimination, capable of differentiating between medical, industrial, and special nuclear materials (SNM) while supporting the steady flow of pedestrian traffic at busy airports, train stations, seaports, border crossings, nuclear facilities, and other critical infrastructure.
