Provided is a detector module for measuring one or more types of radiation, in particular X-ray, gamma ray, or nuclear particle radiation, comprising a detection unit, an analog-to-digital converter, an information processing device, and a memory device for storing the position of the detector module. The detector module comprises at least one light-emitting diode (LED), optically connected with the detection unit for stabilizing the detector unit. Further, the invention provides a stanchion, in particular a portable stanchion, whereby the stanchion comprises a inventive detector module. Yet further, a (wireless) network of detector modules is provided, whereby each detector module is mounted within a stanchion.
