Abstract The effects of electric fields in 400kv substations were examined in 53 workers exposed more than 5 years and compared with a non-exposed matched control group. The investigation included the nervous system (neurasthenic symptoms, psychological tests, EEG), cardiovascular system (symptoms, blood pressure, ECG), the blood (haemoglobin, red blood cells, reticulocytes, white blood cells including differential count, thrombocytes, sedimentation rate) and fertility. There were no differences between the exposed and control groups due to the electric fields. However, the exposed group had consistently better results in the psychological tests, but these differences were ascribed to higher education. Evaluation as to "acute" effects of exposure at some time during the 14 days preceding the examination showed lower psychological test results among the "acute" exposed. No other results indicated the presence of an "acute" effect.
