1. Metal detector gate comprising two uprights (12, 14) housing sensors forming a metal mass detector, particularly transmitter/receiver coils (20, 22), associated with a power supply and processing module (30), and defining between them a channel for individuals to be checked to pass through, at least one of the uprights (12, 14) comprising a series of light sources (40) distributed over its height to display alarms, characterized in that it also comprises a radioactive radiation detector (25) associated with the power supply and processing module (30) and that said module is suitable for controlling the light sources (40) so that a part of the colors generated by the light sources (40) is associated with the signals from the metal mass detector and a different series of colors is associated with the signals from the radioactive radiation detector.
