radiation detection device and detection system combines

The invention relates to a radiation detection device comprising at least two radiation detectors (D1, D2, D3) distributed in series along a cable support (MB), each detector comprising a light-detecting element optically coupled stimulated optically to at least one optical fiber (F1, F2, ..., F3), each light-detecting element optically stimulated being maintained in vis-a-vis a first end of the optical fiber by a mechanical part secured to the support cable, the mechanical part being held in a flexible cable (FL) by holding means, the second ends of each optical fiber emerging at the same first end of the flexible cable.
