The frequency range covered is 0 Hz to 300 GHz. Technical considerations and measurements are necessary for frequencies from d.c. to 20 kHz because no relevant field strengths are expected above due to the physical nature of EMF-sources in the railway environment. a) The regulations regarding the protection of human beings (also bearing active implantable...
