Summary: In a modern city there are numerous sources of electro-magnetic radiation. However, their interaction and overlap are studied extremely insufficiently. We investigated the spatial distribution of strength indicators of electric fields and flux density of magnetic fields in Petrozavodsk. It was established that the intensity of electric fields reaches significant values only near overhead high-voltage lines, but there is no revealed excess of exposure standard outside their security zones. The flux density does not exceed the permissible level, but within the city area it varies wildly. It was represented on the compiled map. The largest levels of the flux density were observed in modern building zones, mainly in the centre of the city. In separate points the abnormal values were noted. They were explained by the influence of underground power cables. The results are useful for working out the method of mapping electrio-magnetic fields.
