Overview

The portal radiation detector is a fast detachable automatic radiation monitoring system equipped with a large volume and high sensitivity gamma detector. The system can perform real-time online radiation monitoring on pedestrians in the passage, detect trace amounts of radioactive substances, automatically issue radiation over limit alarms, and complete the storage of detection data.

Product Details

Portal radioactive detectorThe system can be connected to the higher-level management system to form a remote real-time monitoring information system platform. It is mainly used for rapid radioactive testing of large-scale evacuees after nuclear facility accidents, and can also be used for temporary occasions such as major events and conferences that require radioactive testing of personnel entering the venue.

The rapid deployment channel radioactive automatic monitoring system is a set of quick detachable automatic radiation monitoring systems equipped with large volume and high sensitivity gamma detectors. The system can perform real-time online radioactive monitoring on pedestrians in the channel, detect trace amounts of radioactive substances, automatically issue radiation over limit alarms, and complete the storage of detection data.
