N2 - Radiomagnetotelluric (RMT) is one of the newest and innovative methods of applied geophysics. Military and civilian radio stations broadcasting in the frequency range between 10 kHz and 1 MHz are used as transmitters. Information about the conductivity distribution of the earth can be derived from 1 m to 100 m downwards. A new RMT device was developed which can record time series of electric and magnetic fields in a wide frequency range of 10 kHz to 1 MHz. Transfer functions were determined by spectral analysis using a newly developed processing software. The observed transfer functions in the field are the first ones worldwide in a frequency range above 300 kHz and lead to a better resolution of the shallow structure. RMT measurements were carried out in Ukraine using the new device. The main aim of this field survey is the mapping of kerosene contamination close to a military area. RMT transfer functions and their interpretation by 2D inversion calculations will be demonstrated.
