<p>A method warns persons who are in the vicinity of an high-frequency (HF) field-emitting device, such as an European train control system (ETCS) antenna of a rail vehicle. In order to be able to reliably warn persons of the presence of radiation that is detrimental to health, the HF field is extracted by an antenna arrangement, the extracted signal actuating, by a power-measuring device, a signaling device for the optical and/or acoustic signaling of an ON/OFF state of the device, in particular the ETCS antenna.</p> |
