Nowadays nearly more than half of human beings on the planet are directly or indirectly exposed to an “evolutionary” novel physical agent: the electromagnetic fields (EMFs) emitted by cellular phones, base stations, as well as other types of wireless communication technologies. More than 10 years ago several studies reported that cognitive functions of human beings may have been altered while exposed to radiofrequency (RF) EMFs. Yet, the genuine effect of these non-ionizing radiations on human behaviour was not replicated by several other recent and more methodologically robust studies. Latest reviews and metanalyses confirmed the paucity of evidence in favour of psychomotor and cognitive effects of acute RF EMF exposure on human volunteers in well controlled laboratory settings. Thus, despite persisting concerns on potential biologic effects of acute RF EMFs irradiation, there is substantial lack of evidence that RF radiation can affect cognitive functions in humans.

AbstractOver the past decades, the use of common sources of electromagnetic fields such as Wi-Fi routers and mobile phones has been increased enormously all over the world. There is ongoing concern that exposure to electromagnetic fields can lead to adverse health effects. It has recently been shown that even low doses of mercury are capable of causing toxicity. Therefore, efforts are initiated to phase down or eliminate the use of mercury amalgam in dental restorations. Increased release of mercury from dental amalgam restorations after exposure to electromagnetic fields such as those generated by MRI and mobile phones has been reported by our team and other researchers. We have recently shown that some of the papers which reported no increased release of mercury after MRI, may have some methodological errors. Although it was previously believed that the amount of mercury released from dental amalgam cannot be hazardous, new findings indicate that mercury, even at low doses, may cause toxicity. Based on recent epidemiological findings, it can be claimed that the safety of mercury released from dental amalgam fillings is questionable. Therefore, as some individuals tend to be hypersensitive to the toxic effects of mercury, regulatory authorities should re-assess the safety of exposure to electromagnetic fields in individuals with amalgam restorations. On the other hand, we have reported that increased mercury release after exposure to electromagnetic fields may be risky for the pregnant women. It is worth mentioning that as a strong positive correlation between maternal and cord blood mercury levels has been found in some studies, our findings regarding the effect of exposure to electromagnetic fields on the release of mercury from dental amalgam fillings lead us to this conclusion that pregnant women with dental amalgam fillings should limit their exposure to electromagnetic fields to prevent toxic effects of mercury in their fetuses. Based on these findings, as infants and children are more vulnerable to mercury exposures, and as some individuals are routinely exposed to different sources of electromagnetic fields, we possibly need a paradigm shift in evaluating the health effects of amalgam fillings.

In today’s world, most children are exposed to various manmade electromagnetic fields (EMFs). EMFs are electromagnetic waves less than 300 GHz. A developing child’s brain is vulnerable to electromagnetic radiation; thus, their caregivers’ concerns about the health effects of EMFs are increasing. EMF exposure is divided into 2 categories: extremely low frequencies (ELFs; 3–3,000 Hz), involving high-voltage transmission lines and in-house wiring; and radiofrequencies (RFs; 30 kHz to 300 GHz), involving mobile phones, smart devices, base stations, WiFi, and 5G technologies. The biological effects of EMFs on humans include stimulation, thermal, and nonthermal, the latter of which is the least known. Among the various health issues related to EMFs, the most important issue is human carcinogenicity. According to the International Agency for Research on Cancer’s (IARC’s) evaluation of carcinogenic risks to humans, ELFs and RFs were evaluated as possible human carcinogens (Group 2B). However, the World Health Organization’s (WHO’s) view of EMFs remains undetermined. This article reviews the current knowledge of EMF exposure on humans, specifically children. EMF exposure sources, biological effects, current WHO and IARC opinions on carcinogenicity, and effects of EMF exposures on children will be discussed. As well-controlled EMF experiments in children are nearly impossible, scientific knowledge should be interpreted objectively. Precautionary approaches are recommended for children until the potential health effects of EMF are confirmed.

Direct health effects could result following exposure to RF by thermal (heating effects). Recent Studies have shown that there are public fears on effects that can be caused mainly by holding mobile phones close to the body, or as a result of possible non-thermal effects from both phones and base stations.  This paper offers an overview on the biological effects of electromagnetic radiation caused by mobile phones. Exposures of individuals to RF radiation from these sources will depend upon their proximity and may be above those from mobile phone base stations, although still well below guidelines. From a review of the scientific literature, it is concluded that there were no established health effects from exposure to the RF fields from mobile phones. However, there are gaps in knowledge requiring further research, but current knowledge suggests that RF exposure to levels below the guidelines were not a risk to health.

As the network of cellular mobile phones has recently expanded and in particular after the digital GSM 900/1800/2100 systems have been introduced, the potential effect on human health of electromagnetic radiation from the base stations of these systems has become of great concern to European countries. There have been requests made in some countries for areas free from mobile phones in which installation of base stations would not be permitted and for considerable reduction of the maximum authorised exposure or other restrictions. The European Commission's Recommendation adopted on 12 July 1999 requires that the maximum field strength for electromagnetic radiation (0–300 GHz) is established and that information about population's exposure to EMF and the measures taken to reduce it is provided. The article presents and analyses EMFs produced by mobile communication antennas in a residential area. Measurements of the electric strength, magnetic strength and EMF power density were performed and compared to the established hygiene norms. Tests were conducted in the near- and far-field of the antenna, on residential premises located directly in front of the antenna within its main radiation lobe. In addition, there were performed measurements of electromagnetic fields produced by mobile communication in rural areas. Santrauka Pastaruoju metu paplitus koriniam mobiliųjų telefonų tinklui ir ypač – įvedus skaitmenines GSM900/1800/2100 sistemas, daugelyje Europos šalių pradėta rūpintis dėl galimo šių sistemų bazinių stočių elektromagnetinės spinduliuotės poveikio žmogaus sveikatai. Kai kuriose šalyse imta reikalauti zonų be mobiliųjų telefonų, kuriose būtų draudžiama įrengti bazines stotis, gerokai sumažinti didžiausiąją leidžiamąją apšvitą ar įvesti kitus ribojimus. 1999 m. liepos 12 d. priimta Europos Tarybos rekomendacija nurodo nustatyti maksimalių elektromagnetinės spinduliuotės (0–300 GHz) laukų stiprį, reikalauja teikti informaciją apie gyventojų apšvitą dėl elektromagnetinių laukų bei taikomas priemones jai sumažinti. Pateikiami ir nagrinėjami gyvenamojoje zonoje mobiliojo ryšio antenų sukuriamų elektromagnetinių laukų duomenys. Atlikti elektrinio stiprio, magnetinio stiprio ir elektromagnetinio lauko energijos srauto tankio matavimai. Duomenys lyginami su nustatytomis higienos normomis. Tyrimai atlikti artimojoje ir tolimojoje antenos zonoje, gyvenamosiose patalpose, esančiose prieš anteną. Mobiliojo ryšio elektromagnetinių laukų matavimai atlikti ir kaimo vietovėse.

There has been a dramatic increase in the use of mobile phone technology in the last decades, with widespread benefits in many professional and private activities. In parallel with this, the concern regarding the possibility of adverse health effects due to the absorption of electromagnetic fields by humans also increased. For several years, many research groups in different countries were developing research projects on these subjects in the areas of medicine, biophysics, engineering, etc. Also, the World Health Organization (WHO) has coordinate efforts including many countries to access the existing scientific evidence of harmful health effects of non ionizing radiation (NIR) emitted from different communication equipment, such as the mobile phones and their base stations, with special emphasis to the non-thermal effects. In principle, the base stations radiate more energy. However, their antennas are usually located on the top of elevated towers (or masts) and the radiated energy is mainly concentrated in the horizontal direction. Therefore people are usually far from these antennas, and also in directions reasonably apart from those of maximum radiation. Because the conventional monopole (or whip) antennas being used now in mobile phones typically show a circular radiation pattern in the horizontal plane, they may radiate substantial levels of energy in almost all directions, very close to the body and during considerable time. It is observed that when they are operated very close to the user’s head (e.g., 2,5 cm or less) , most of energy is absorbed in the head tissues (such as the bone, the brain, eye, etc), and less energy is radiated to the nearest base station. This situation is undesirable since quality of communication is worse, and the Specific Absorption Rate (SAR) in the user’s head and the battery drain are increased.
