PROBLEM OF EVALUATION OF EEG FINDING IN RELATION TO THE GRADE OF EXPOSURE TO USW RADIOWAVES
Styblova V., Holovska V., Spondova V., Zubrik L. · 1973
An EEG study of 42 TV station employees exposed to 48.5-230 MHz fields found no significant EEG differences from controls.
Plain English Summary
This study evaluated EEG (brain wave) findings in 42 employees of TV stations exposed to ultra-short wave (USW) radiowaves, in relation to the grade of exposure, and assessed whether electromagnetic energy at that dose damages the central nervous system. The emitters' frequency band was 48.5-230 MHz with a mean field intensity of 2.9 V/m. The authors found no significant differences in the EEG findings between the exposed persons and the control group, and concluded that the dose does not damage the CNS.
Why This Matters
This occupational study examined EEG findings in 42 employees of TV stations. The mean value of irradiation for one working day, the sum of field intensity in V/m and exposure time in hours, was 30.7 (range 6.5-97.1), against a threshold limit of up to 80.
The authors found no significant differences in the EEG findings between the exposed group and the control group, in agreement with other authors and with the results of clinical examination. A significant coincidence was found between the incidence of headache and the percentage of EEG abnormality, particularly in migraine. The authors believe that some authors erroneously interpret such EEG findings as brain damage by electromagnetic radiation, and that EEG abnormality in exposed persons should always be assessed in relation to the incidence of migraine.
Finding
The authors found no significant differences in the EEG findings in the group of exposed persons and in the control group, this being in agreement with other authors and with the results of clinical examination.
In their words
“The authors found no significant differences in the EEG findings in the group of exposed persons and in the control group, this being in agreement with other authors and with the results of clinical examination.”
Exposure Details
- Electric Field
- 2.9 V/m
Exposure Context
This study used 2.9 V/m for electric fields:
- 9.7x above the Building Biology guideline of 0.3 V/m

It is believed that these EEG findings are erroneously interpreted by some authors as a manifestation of brain damage by electromagnetic radiation. The authors believe that electromagnetic energy at the dose to which the mentioned groups were exposed does not damage the CNS, and that the EEG abnormality in exposed persons should always be assessed in relation to the incidence of migraine.
