研究目的(著者による)

To study the relation between exposure from mobile telecommunication and other radiofrequency electromagnetic field and the association between exposure and symptoms.

詳細情報

In a cross-sectional study of randomly selected inhabitants living in urban and rural areas of Austria for more than one year near to 10 selected base stations, 365 subjects were examined.

研究の主なアウトカム(著者による)

Self-reported symptoms like headache and difficulties in concentrating show an association with microwave exposure from base stations, not attributable to subject's fear of health effects from the base stations. Despite the influence of confounder variables (like fear of adverse effects from exposure) there was a significant relation of some symptoms to measured power density; this was highest for headaches.
Perceptual speed increased, while accuracy decreased insignificantly with increasing exposure levels. There was no significant effect on sleep quality.
The data show that effects of very low exposure to high frequency electromagnetic fields on well being and performance cannot be ruled out; however, mechanisms of action at these low levels are unknown.
