To study the effects of radiofrequency electromagnetic fields on the brain physiology of adolescents.
Different studies have shown an influence of pulsed radiofrequency electromagnetic fields on the wake and sleep EEG in adults. In 2006, the WHO highlighted that further radiofrequency electromagnetic field provocation studies on children of different ages are required to estimate the risks, especially of mobile phone usage. Therefore, in the present study, adolescents were examined. During exposure (low SAR (0.35 W/kg), high SAR (1.4 W/kg) or sham exposure at weekly intervals), 22 adolescents performed cognitive tasks. EEG was recorded during baseline (before exposure), immediately after, and 30 and 60 min after exposure.
No clear significant exposure-related effects on the waking EEG or cognitive functions were found in adolescents. The data did not provide evidence for a higher sensitivity of adolescents to radiofrequency electromagnetic fields than adults.
