The GCS-SPEC Series of drive-through radiation portal monitors are trusted worldwide to detect and identify radioactive nuclides. Its modular design allows the GCS-SPEC Series to be configured with two or more detector panels to support high throughput security at border crossings, seaports, critical infrastructure, and high threat facilities.
