Abstract

OBJECTIVE: To investigate whether the pulsed high-frequency electromagnetic field (pulsed EMF) emitted by a mobile phone for 30 min has short-term effects on human somatosensory evoked potentials (SEPs). METHODS: We studied somatosensory evoked potentials (SEPs) in 12 normal volunteers before and after exposure to the electromagnetic field emitted by a mobile phone for 30 min compared with sham exposure. In 7 out of the subjects we also measured the recovery function of the SEP. RESULTS: Neither SEPs nor their recovery function was affected by exposure to pulsed EMF emitted by a mobile phone or sham phone use. CONCLUSIONS: As far as the present methods are concerned, 30 min mobile phone use has no short-term effects on the human sensory cortex. SIGNIFICANCE: This is the first study of SEPs after electromagnetic exposure by the mobile phone. Our results support the safety of the mobile phone.
