Background
Radio-frequency electromagnetic fields (RF EMF) of mobile communication systems are
widespread in the living environment, yet their effects on humans are uncertain despite a
growing body of literature.
Objectives
We investigated the influence of a Universal Mobile Telecommunication System (UMTS)
base station-like signal on well being and cognitive performance in subjects with and without
self-reported sensitivity to RF EMF.
Methods
We performed a controlled exposure experiment (45 min at an electric field strength of 0, 1 or
10 V/m, incident with a polarization of 45o from the left back side of the subject, weekly
intervals) in a randomized, double-blind crossover design. 117 healthy subjects (33 self-
reported sensitive, 84 non-sensitive subjects) participated in the study. We assessed well
being, perceived field strength and cognitive performance with questionnaires and cognitive
tasks and conducted statistical analyses using linear mixed models. Organ and brain tissue
specific dosimetry including uncertainty and variation analysis was performed.
Results
In both groups, well being and perceived field strength were not associated with actual
exposure levels. We observed no consistent condition-induced changes in cognitive
performance except for two marginal effects. At 10 V/m, we observed a slight effect on speed
in one of six tasks in the sensitive subjects and an effect on accuracy in another task in non-sensitive subjects. Both effects disappeared after multiple endpoint adjustment.
Conclusions
In contrast to a recent Dutch study, we could not confirm a short-term effect of UMTS base
station-like exposure on well being. The reported effects on brain functioning were marginal
and may have occurred by chance. Peak spatial absorption in brain tissue was considerably
smaller than during usage of a mobile phone. No conclusions can be drawn regarding short
term-effects of cell phone exposure or the effects of long-term base station-like exposure on
human health.

Effect of 910-MHz electromagnetic field on rat bone marrow.
Department of Environmental and Natural Resources Management, Ioannina University, Seferi 2, Agrinio 30100, Greece. gntemsia@cc.uoi.gr
Aiming to investigate the possibility of electromagnetic fields (EMF) developed by nonionizing radiation to be a noxious agent capable of inducing genotoxicity to humans, in the current study we have investigated the effect of 910-MHz EMF in rat bone marrow. Rats were exposed daily for 2 h over a period of 30 consecutive days. Studying bone marrow smears from EMF-exposed and sham-exposed animals, we observed an almost threefold increase of micronuclei (MN) in polychromatic erythrocytes (PCEs) after EMF exposure. An induction of MN was also observed in polymorphonuclear cells. The induction of MN in female rats was less than that in male rats. The results indicate that 910-MHz EMF could be considered as a noxious agent capable of producing genotoxic effects

Abstract
This Study focuses upon an aspect of how living organisms and humans in particular can be adversely affected by highly coherent electromagnetic fields of technological origin, in a way that is not entertained or addressed by existing Safety Guidelines – namely, through the possibility of nonthermal, frequency-specific influences of an informational nature. Supporting evidence is presented, and attention drawn to a disturbing consistency between some of these influences and the nature of certain adverse health effects found amongst some exposed people. On the basis of a detailed analysis of the present situation, a number of recommendations are made to promote a higher degree of electromagnetic biocompatibility between these fields and the living human organism than currently obtains.

Final Report REFLEX Project
-

The Report of the European Union's REFLEX Project (Risk Evaluation of Potential Environmental Hazards from Low Frequency Electromagnetic Field Exposure Using Sensitive in vitro Methods) was released in November, 2004. The Project studied ELF and RF exposures to various cell types. Swedish RF researcher and epidemiologist Lennart Hardell has sent the link to the entire 291-page report (See below. It's a long download, so be patient).

From 7.12 Summary
... the omnipresence of EMF's in infrastructures and consumer products have become a topic of public concern. This is due to the fear of people that based on the many conflicting research data a risk to their health cannot be excluded with some certainty. Therefore, the overall objective of REFLEX was to find out whether or not the fundamental biological processes at the cellular and molecular level support such an assumption. For this purpose, possible effects of EMFs on cellular events controlling key functions, including those involved in carcinogenesis and in the pathogenesis of neurodegenerative disorders, were studied through focussed research. Failure to observe the occurrence of such key critical events in living cells after EMF exposure would have suggested that further research efforts in this field could be suspended and financial resources be reallocated to the investigation of more important issues. But as clearly demonstrated, the results of the REFLEX project show the way into the opposite direction.
Key emphases of the REFLEX Project were to develop reliable exposure equipment, to assure that exposure parameters were consistent and thoroughly documented, and to examine how differences in techniques for cell culture preparation such as staining of specimens yielded differing results. Along with consistency in genotype of study specimens, these emphases are of crucial importance to the replication of studies from one laboratory to another.
