GR-500 Series Radiation Portal Monitor (RPM)

Overview

The GR-500 Series is a portal radiation monitoring system (RPM) that is designed to detect the presence of a shielded radioactive source buried in a moving vehicle. Vehicles pass between two large detectors at a controlled speed, and using sophisticated algorithms, the detector output is analyzed and in turn provides visual and audible alarms indicating the location of the radioactive source. The system offers reliable, year-round operation and is suitable for:

• Trucks
• Trains
• Chargebuckets
• Containers
• Conveyors

Applications

Government and private businesses, around the world count on the GR-500 Series and the upgraded AT-900S systems to detect the presence of radioactive emissions.

• Scrap metal industry
• Rail yards
• Industrial

Features

A GR-500 Series detection system consists of one controller unit, called a console, and one to eight detector assemblies. The GR-500 offers comprehensive tools to help detect deeply buried sources, including unique alarm thresholds for each vehicle based on its individual radiation profile and the ability to set low alarm thresholds - 30%-50% below natural background.

• Advanced electronics design
• Reliable, automatic, 24 hr/7 day operation

Benefits

Using the GR-500 Series Portal Radiation Monitoring System is a fast, reliable way to detect radioactive sources encased in metal shields and prevent contamination during the steel making process. The system uses advanced technology enabling the operator to easily monitor trucks and railcars for shielded sources, providing the best opportunity to reject any contamination before it enters or exits your site. With the GR-500 Series, the high costs associated with the decontamination, storage and disposal of radioactive sources can be avoided. See Photo 1, See Photo 2
