EEG has no radiation. EEG is a sophisticated electronic instrument that is connected to the human body through scalp electrodes and is able to amplify and record the biological potential of the brain and obtain the corresponding graph. The EEG itself does not produce electronic radiation, nor radioactive radiation, but records the bioelectric phenomena generated by the human body itself. The EEG records the spontaneous and rhythmic electrical activity of brain cell groups. EEG is a commonly used adjunct to neurology and can help identify a variety of diseases, such as epilepsy, psychiatric disorders, tumors, trauma, encephalitis, and can also be used to determine brain death in patients.
