Objective: Identify, describe and make a list of artifacts that are caused by a wide range of electromagnetic radiation: from 3 to 3000 MHz.

Materials and Methods: Original method of research (has no analogues in clinical practice) has been developed.
Nihon Kohden donates equipment for research; Volynskaya Bolnica Hospital #1 of the Department for Presidential Affairs of the Russian Federation provides support in the format of advisers and equipment; Center of Speech Pathology and Neurorehabilitation provides support in the format of advisers; The Ministry of Education and Science of the Russian Federation provides administrative support.

Results: Systematized and described artifacts identified for further development of methods of the electroencephalogram in the presence of the background of technogenic electromagnetic radiation.

Discussion: At present portable EEG-devices are widely used. The influence of artificial electromagnetic radiation (EMR) is actual for the quality of recording brain activity. A lot of artifacts are considered non-physiological artifacts that are caused by a wide range of electromagnetic radiation: from 3 to 3000 MHz. Considering the above, the identification, description and making a list of these artifacts is a priority now. It will make it possible to create a software filter for EEG-systems.
Artificial electromagnetic radiations have a major impact on the EEG recording. This fact prevents an accurate diagnosis. Original method of research (has no analogues in clinical practice) has been developed. That will allow recording the EEG in any unprepared urban environments to create a method of excluding impacts to the above.

Key words: artefact, EEG, EMR, functional diagnostics.
