GSM phone signals produced no immediate symptoms during 30-60 minute exposures, but this doesn't address long-term cumulative health effects.

Plain English Summary

Summary written for general audiences

Finnish researchers exposed healthy volunteers to GSM mobile phone signals (902 MHz) for 30-60 minutes and measured whether they experienced symptoms like headaches, dizziness, fatigue, or skin sensations. The study found no difference in reported symptoms between exposure and non-exposure sessions, suggesting that short-term GSM phone radiation doesn't cause immediate subjective symptoms in healthy people.

Study Details

The influence of pulsed radiofrequency (RF) electromagnetic fields of digital GSM mobile phones (902 MHz, 217 Hz pulse modulation) on subjective symptoms or sensations in healthy subjects were studied in two single-blind experiments.

The duration of the RF exposure was about 60 min in Experiment 1 and 30 min in Experiment 2. Each su...

The results did not reveal any differences between exposure and non-exposure conditions, suggesting ...
