Fifteen minutes of mobile phone exposure produced no detectable thermal effects in teenage boys' heads, but longer exposures remain unstudied.

Plain English Summary

Summary written for general audiences

Finnish researchers exposed 26 teenage boys (ages 14-15) to GSM 900 mobile phone radiation for 15 minutes to measure thermal effects and blood flow changes in their heads. They found no significant increases in ear canal temperature, no changes in local brain blood flow, and no interference with the autonomic nervous system. This controlled study suggests that short-term mobile phone exposure at typical power levels doesn't produce measurable thermal effects in adolescents' heads.

Study Details

The aim of this study was to examine thermal and local blood flow responses in the head area of the preadolescent boys during exposure to radiofrequency (RF) electromagnetic fields produced by a GSM mobile phone.

The design was a double-blinded sham-controlled study of 26 boys, aged 14-15 years. The SAR distribu...

During the short-term RF exposure, local cerebral blood flow did not change, the ear canal temperatu...
