Abstract
In this report a double blind randomized three-way crossover evaluation of general symptoms and cognitive functions with or without exposure to GSM and UMTS-like fields in subjects presenting with complaints subjectively attributed to GSM fields is presented. From our research it is concluded that our hypotheses to find no relation between presence of RF-fields and the measured parameters is rejected. We have found statistically significant relation between UMTS-like fields with a field strength of 1 V/m and an effect on the Well Being. Further, from the cognitive tasks, it is observed that a number of significant effects is found. Each exposure frequency is associated with changes in some tasks or parameters, while other frequencies are not. In our study, it is shown that the thermal effects are negligible and therefore, an explanation based on thermal effects seems highly unlikely for effects on the cognitive parameters. Without any question, the results justfiy more scientific research into this area.
