The goal of this research was to determine whether a relation exists between electromagnetic fields and the subjective complaints together with cognitive performance associated with an electromagnetic stimulus. Note that only effects present during and shortly after exposure to electromagnetic fields have been studied. In addition, we examined whether thermal effects can be responsible for possible effects found in this study.
This research goal was pursued by using a double blind crossover design in order to investigate the real influence of fields on the complaints reported. Comparing the complaints as reported by the subjects with and without the presence of GSM and UMTS-like fields, and without their knowledge of that exposure condition, eliminates subjectivity. At the same time cognitive functions have been evaluated.
