Short-term exposure at 1 V/m to GSM and UMTS base station signals produced no statistically significant differences in cognitive performance or physiological measures compared with sham exposure in either sensitive or non-sensitive individuals.

Plain English Summary

Summary written for general audiences

The study aimed to determine whether short-term exposure at 1 V/m to typical GSM and UMTS signals affects cognitive performance and physiological parameters. The sample included 200 subjects, with 50.0% reporting idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF) and 50.0% non-IEI-EMF. No statistically significant differences were found between real exposure and sham exposure for cognitive performance or physiological effects in either group (P’s > 0.05).

Why This Matters

Cognitive performance was measured with the computer-administered Cambridge Neuropsychological Test Automated Battery (CANTAB eclipseTM). Four CANTAB tests were selected: Reaction Time (RTI), Rapid Visual Processing (RVP), Paired Associates Learning (PAL) and Spatial Span (SSP). Physiological parameters were analyzed using paired sample t-tests.

Study Details

The aim of this study is to clarify whether short-term exposure at 1 V/m to the typical Global System for Mobile Communication and Universal Mobile Telecommunications System (UMTS) affects cognitive performance and physiological parameters (body temperature, blood pressure and heart rate).
