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, each 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 said light sources emit a first color on detecting metal masses and emit a second color, different from the first color, on detecting a radioactive radiation, and wherein the power supply and processing module 30 is suitable for driving the two series of light sources (40) provided respectively on each of the two uprights (12, 14) differently according to the lateral horizontal position of the detected objects and said metal detector gate further comprises:

  • i) identical power supplies for the two series of sources (40) for an object detected in the center of the gate,ii) a power supply only for the series of sources (40) located on the left side of the gate for an object detected on the left side of the gate, andiii) a power supply only for the series of sources (40) located on the right side of the gate for an object detected on the right side of the gate.
