The invention relates to measuring, with a measuring device with a detector, a radiation, such as magnetism or light, which originates from the interior space of the housing of a B-relay. This radiation leaves this internal space and comes in the immediate vicinity of the housing of the B-relay, in which immediate vicinity the measuring device measures this radiation with the detector. A relay box contains a large number of relays. These relays are in an own relay housing which is provided with a for a radiation coming from the housing sensitive external, individual detector. This relay box is associated with a railroad and applied to security level in the management and control of switches or railway crossings, or used for track occupancy detection, such as a so-called repeat relay.
