Effects of global communication system radio-frequency fields on well being and congnitive functions of human subjects with and without subjective complaints.
Prof dr. ir. A.P.M. Zwamborn, Dr. ir. S.H.J.A. Vossen, ir. B.J.A.M. van Leersum, ing. M.A. Ouwens, W.N. Mäkel - september 2003 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.

REFLEX Project Summary

-
REFLEX (Risk Evaluation of Potential Environmental Hazards from Low Energy Electromagnetic Field (EMF) Exposure Using Sensitive in vitro Methods) was a 3-year joint research project within the 5th EU Framework Program. Among the 12 participating research groups, the IT'IS Foundation/ETH was responsible for providing the exposures (signal definitions, exposure setups and technical quality assurance) of all subprojects. Direct comparison of the results was possible between the participants by maintaining common, strictly controlled exposure conditions. REFLEX reported several genotoxic effects as well as effects on gene expression.
The IT'IS Foundation is committed to conducting replications and extensions with the utmost scientific scrutiny in the shortest possible time. Experiments are currently being conducted at the BioCenter in Basel, the Department of Human Biology and Genetics in Kaiserslautern and the Finnish Radiation and Nuclear Safety Authority.

11 000 citizen initiatives already joined together nationwide in order to fight against the rapid extending of the cellular phone network installations in Germany. Already now, the day has over 100 million cellphone conversation minutes in Germany so far. However how big are the dangers real? Dr. Günter Baumgart spoke for BIO with the medical physicist Dr. von Klitzing.

In Salzburg is een provocatieonderzoek gedaan vergelijkbaar met het TNO Cofam en ''het Zwitserse onderzoek''. Mensen werden kortstondig blootgesteld aan hoogfrequente elektromagnetische straling. Naast de invloed op het subjectieve welbevinden zijn ook monsters genomen (spuug). Er deden 57 proefpersonen mee en er was sprake van een gerandomiseerde en dubbelblinde opzet, wat placebo-effecten nagenoeg uitsluit.
Bij relatief lage vermogensdichtheden (500 uW/m2) werden al duidelijke biologische effecten gevonden. (n.b. de blootstellingslimiet in Nederland is 10.000.000 uW/m2)
Het lichaamseigen afweersysteem werd daadwerkelijk verzwakt. Biochemisch werd uit de speekselanalyse duidelijk dat hogere blootstellingen tot een relevante immuniteitsonderdrukking leidden. Zo was er een statistisch significante verandering in de cortisolspiegel (ook wel het stresshormoon genoemd. Daarnaast waren er opvallende veranderingen in het verloop van de alfa-amylase-spiegel (amylase is zetmeelverteringsenzym), wat tevens als een sterke stress-marker aan te merken is. Hetzelfde gold voor de immunoglobulin-A-spiegel (antilichamen in het speeksel).
Op het gebied van welbevinden werden geen statistisch significante effecten gemeten. Dit was te verwachten aangezien de opzet erg onhandig is om dit soort effecten te kunnen vinden. Zo was de blootstellingstermijn te kort en werd er wel wat rekening gehouden met voorbelasting, maar lang niet voldoende.
