Cell phones don't affect brain waves, study reveals

Cell phone junkies, take note: concluding a small, three-year study, a neurological clinic in Munich this week said it found no harmful effects from cell phones on human brain waves.

The study, commissioned by Bavaria's Environmental Ministry, looked at 39 mobile phone users whom it deemed "not overly sensitive to electromagnetic waves". There was no explanation as to how participants were chosen, and researchers at the neurological clinic at the Grosshadern Hospital in Munich -- where the studied was carried out -- could not be reached for comment.

The study measured the effects on participants in a variety of tests over a three-year period, according to a summary of the study results released by the Bavarian Environmental Ministry. Electrodes were attached to each participant, who received either a car telephone with an antenna or a mobile phone registered with one of two mobile phone networks in Germany. The participants -- 21 women and 18 men between the ages of 16 and 58 -- were not aware of whether the phones were on or off during the tests.

The researchers found that the phones had no impact on participants' brain waves, whether the phones were on or off, according to the summary.

Many people have voiced concerns over the effects of electromagnetic waves on human health. The study is part of the Ministry's efforts to analyse what effect these electromagnetic fields have on humans and the environment.
