Neither the UMTS- nor the GSM-EMF produced any significant changes in the measured parameters compared to sham exposure.

Plain English Summary

Summary written for general audiences

Researchers tested the effects of 1950 MHz UMTS at 0.1 and 1 W/kg and pulsed 900 MHz GSM at 1 W/kg on event-related potentials and behavioral measures in 15 healthy right-handed subjects. The study used a double-blind, randomized, crossover design. Neither the UMTS- nor the GSM-EMF produced any significant changes in the measured parameters compared to sham exposure. The results do not give any evidence for a deleterious effect of the EMF on normal healthy mobile phone users.
