“…Chance is, however, not a plausible explanation for the exceptional accurate on/off judgment of two participants in one trial because the p-values were below 10 À21 [29]. The probability of achieving such a performance by chance is as low as achieving six correct hits in a lottery (6 out of 49) three times in a row.…”

This is an update of a previous systematic review on the association between radiofrequency electromagnetic field (RF-EMF) exposure and health-related quality of life that included studies published before August 2007 [1]. Since then, nine randomized trials addressed short-term exposures from close-to-body RF-EMF sources such as mobile phones, and two observational studies investigated the effects of mobile phone use on health-related quality of life. Six randomized trials addressed short-term far-field exposure arising, for instance, from mobile phone base stations, and eight studies evaluated the effects of environmental far-field RF-EMF exposure. In most of the randomized trials, no exposure-response association was observed. The sporadically reported associations did not show a consistent pattern regarding the type of symptoms or the direction of the effects (increase/decrease). Similarly, most of the recent observational studies did not show associations between RF-EMF exposure and non-specific symptoms. However, the exposure gradients were small and possible exposure misclassification is a limitation of these studies. Longitudinal studies as well as studies in children and adolescents are scarce. In summary, recent research did not indicate health-related quality of life to be affected by RF-EMF exposure in our everyday environment. Furthermore, none of the studies showed that individuals with self-reported electromagnetic hypersensitivity (EHS) were more susceptible to RF-EMF than the rest of the population. Nevertheless, the rapid technological development and anticipated increase in exposure levels warrant the conduct of further longitudinal studies. Due to the widespread use of wireless communication technologies potential adverse health effects would have major public health consequences.

“…Frick et al [2005] reported that their experiment using transcranial magnetic stimulation did not support the hypothesis that subjectively electrosensitive patients suffered from a physiological hypersensitivity to EMFs stimuli. Another study by Kwon et al [2008] also provided lack of evidence for the existence of electromagnetic perception to the Global System for Mobile Communications (GSM) mobile phone EMF. In a recent review, Röösli [2008] concluded that the available provocation studies do not indicate that people can perceive radio frequency (RF)-EMF or that symptoms are directly invoked by them.…”

With the number of cellular phone users rapidly increasing, there is a considerable amount of public concern regarding the effects that electromagnetic fields (EMFs) from cellular phones have on health. People with self-attributed electromagnetic hypersensitivity (EHS) complain of subjective symptoms such as headaches, insomnia, and memory loss, and attribute these symptoms to radio frequency (RF) radiation from cellular phones and/or base stations. However, EHS is difficult to diagnose because it relies on a person's subjective judgment. Various provocation studies have been conducted on EHS caused by Global System for Mobile Communications (GSM) phones in which heart rate and blood pressure or subjective symptoms were investigated. However, there have been few sham-controlled provocation studies on EHS with Code Division Multiple Access (CDMA) phones where physiological parameters, subjective symptoms, and perception of RF radiation for EHS and non-EHS groups were simultaneously investigated. In this study, two volunteer groups of 18 self-reported EHS and 19 non-EHS persons were tested for both sham and real RF exposure from CDMA cellular phones with a 300 mW maximum exposure that lasted half an hour. We investigated not only the physiological parameters such as heart rate, respiration rate, and heart rate variability (HRV), but also various subjective symptoms and the perception of EMF. In conclusion, RF exposure did not have any effects on physiological parameters or subjective symptoms in either group. As for EMF perception, there was no evidence that the EHS group better perceived EMF than the non-EHS group.

“…Ponieważ ucho sąsiaduje ze źródłem PEM, którym jest telefon komórkowy, więk-szość badań ukierunkowywano na sprawdzenie oddziaływania PEM na układu słuchowy, w tym na słu-chowe potencjały wywołane -w trakcie lub po ekspozycji, a nawet po ekspozycji wielokrotnej. Nie zaobserwowano w tych badaniach żadnych skutków oddziały-wania PEM [37][38][39][40][41][42][43][44][45][46]. Również badania na zwierzętach nie wykazały takiego oddziaływania [47].…”

StreszczenieW organizmie ludzkim do układów najbardziej "elektrycznych" należy układ nerwowy oparty na elektroprzewodzących sieciach neuronalnych. W związku z tym od lat prowadzone są badania mające na celu sprawdzenie wpływu pól elektromagnetycznych (PEM) o różnych częstotliwościach na jego funkcjonowanie. W pracy zaprezentowano wyniki przeglądu literatury naukowej poświęconej oddziaływaniu PEM na funkcjonowanie ludzkiego układu nerwowego, przy czym szczególny nacisk położono na najnowsze prace dotyczące współczesnych bezprzewodowych systemów łączności i transmisji danych. Wyniki opublikowanych prac w większości analizowanych obszarów nie wykazują wpływu PEM na układ nerwowy. Wyjątkami są oddziaływanie sygnału telefonii GSM na zapis EEG -spoczynkowy i podczas snu badanych osób -oraz wpływ częstotliwości radiofalowych na regulację układu krążenia. W pozostałych analizowanych obszarach (wpływ na sen, potencjały wywołane i procesy poznawcze) nie ma spójnych wyników prac świadczących zdecydowanie o oddziaływaniu PEM. Neurofizjologiczne badania wpływu fal radiowych i mikrofal na funkcje mózgu u ludzi nie przyniosły dotychczas jednoznacznych wyników. Przyczynami tego są m.in. różne warunki ekspozycji, duża liczba badanych zmiennych, brak powtarzalności badań i wątpliwości natury statystycznej. Istnieją już jednak wskazówki metodyczne dające szansę na ujednolicenie badań, które zdecydowanie nadal powinny być prowadzone, żeby określić biofizyczne mechanizmy oddziaływania PEM na układ nerwowy. Jednym z aspektów, na które coraz częściej zwraca się uwagę, jest uwzględnianie w badaniach oddziaływania PEM różnic osobniczych. Med.

The research of the effects of electromagnetic fields (EMFs) of different frequencies on its functioning have been carried out for years. This paper presents the results of the scientific literature review on the EMF influence on the functioning of the human nervous system with a particular emphasis on the recent studies of the modern wireless communication and data transmission systems. In the majority of the analyzed areas the published research results do not show EMF effects on the nervous system, except for the influence of GSM telephony signal on resting EEG and EEG during patients' sleep and the influence of radiofrequency EMF on the cardiovascular regulation. In other analyzed areas (EMF impact on sleep, the evoked potentials and cognitive processes), there are no consistent results supporting any influence of electromagnetic fields. Neurophysiological studies of the effect of radio-and microwaves on the brain functions in humans are still considered inconclusive. This is among others due to, different exposure conditions, a large number of variables tested, deficiencies in repeatability of research and statistical uncertainties. However, methodological guidelines are already...
