Details

This system uses a machine learning algorithm to assess alarms triggered by radiation portal monitors at Canadian border crossings. When a cargo container passes through a portal monitor and triggers an alarm, the algorithm helps border officers decide whether the alarm indicates a genuine threat or a benign source of radiation. No personal information is processed. Border officers are informed that AI is used in this process.
