Abstract: Cross-sectional quantitative electroencephalogram (qEEG) study (1996—2001) among Chernobyl accident survivors, who had confirmed acute radiation sickness and were irradiated in dose of 1—5 Gy, revealed the neurophysiological markers of ionizing radiation. Neuropsychological markers were: left fronto-temporal dominant frequency reduction; absolute δ-power lateralization to the left (dominant) hemisphere; relative δ-power increase in the fronto-temporal areas; absolute θ-power decrease in the left temporal region; absolute and relative α-power diffusive decrease, which may reflect cortico-limbic dysfunction lateralized to the left, dominant hemisphere, with the fronto-temporal cortical and hippocampal damage. Quantitative electroencephalogram proposed for differentiation of radiation and nonradiation brain damages and as a new biological dosymetry method. High radiosensitivity of the brain, neocortex, and dominant hemisphere higher radiosensitivity are discussed.
