Guardian™ VM500 Series detects radioactive sources hidden within passenger vehicles; small trucks; and heavy, wide-load trucks at border crossings, ports, airports, critical infrastructure, and nuclear facilities. It offers State of Health monitoring to ensure that the radiation portal monitor (RPM) is operating at peak performance. Its industry leading software allows for customization of screens and settings, optimizing personnel and system performance. Detector sensitivity levels are adjusted based on the needs of the site, providing exceptional NORM discrimination which minimizes nuisance alarms and the need for time-consuming manual inspections.
