During recent years there has been increasing public concern on potential health risks from power-frequency fields (extremely low frequency electromagnetic fields; ELF) and from radiofrequency/microwave radiation emissions (RF) from wireless communications. Non-thermal (low-intensity) biological effects have not been considered for regulation of microwave exposure, although numerous scientific reports indicate such effects. The BioInitiative Report is based on an international research and public policy initiative to give an overview of what is known of biological effects that occur at low-intensity electromagnetic fields (EMFs) exposure. Health endpoints reported to be associated with ELF and/or RF include childhood leukaemia, brain tumours, genotoxic effects, neurological effects and neurodegenerative diseases, immune system deregulation, allergic and inflammatory responses, breast cancer, miscarriage and some cardiovascular effects. The BioInitiative Report concluded that a reasonable suspicion of risk exists based on clear evidence of bioeffects at environmentally relevant levels, which, with prolonged exposures may reasonably be presumed to result in health impacts. Regarding ELF a new lower public safety limit for habitable space adjacent to all new or upgraded power lines and for all other new constructions should be applied. A new lower limit should also be used for existing habitable space for children and/or women who are pregnant. A precautionary limit should be adopted for outdoor, cumulative RF exposure and for cumulative indoor RF fields with considerably lower limits than existing guidelines, see the BioInitiative Report. The current guidelines for the US and European microwave exposure from mobile phones, for the brain are 1.6 W/Kg and 2 W/Kg, respectively. Since use of mobile phones is associated with an increased risk for brain tumour after 10 years, a new biologically based guideline is warranted. Other health impacts associated with exposure to electromagnetic fields not summarized here may be found in the BioInitiative Report at

In addition, exposure to ELFs for a long duration of time may cause calcium (Ca 2 + ) level alterations in nervous system cells and neurons, and induce oxidative stress (Fig. 3) (Hardell and Sage, 2008).

    ABSTRACT: The objective of this review paper was to raise awareness about exposure to low levels of electromagnetic field (EMF) in children, arising from electrical power sources and mobile phones. This exposure may lead to the cognitive and behavioral impairment of brain function; therefore, being aware of these dangers is important to the healthy developmental process of children. When the current data were considered in detail, it was noted that children are not more or less sensitive to EMFs emitted by wireless devices, when compared to adults. Overall, the information about absorption in the crania of children and adults in the literature is not clear.

    • "The problem of " electromagnetic compatibility " of nature and sources of electromagnetic radiation (EMR) is becoming increasingly important [2]. To date, significant correlation between the activity of this factor and the vital functions of various living beings are being established [3]. Microorganisms are widespread in nature and form the basic ecological and trophic links in the functioning of the biosphere. "

    ABSTRACT: Continuous increase in the number and the variety of anthropogenic sources of electromagnetic radiation causes a high interest in studying the effects ultrahigh frequency on living organisms. In the present research influence of UHF EMR (15 W, 2.45 GHz) for 5 and 15 min on morphological and genetic peculiarities of Photobacterium phosphoreum colonies was studied. It has been revealed that UHF EMR affected colony growth parameters, induced transcriptional activity of luciferase encoding gene expression and that the effect was depended on exposure duration. The subsequent cultivation of bacteria during a two week period after treatment showed maintaining of the increased luxb mRNA level in irradiated colonies. Opposite bacterial stress responses were detected to UHF EMR and elevated temperature treatments that assumed UHF EMR comprised of not only thermal but specific component of non-thermal nature.

    • "The effect of EMF emitted by mobile phones on the developing embryo/fetus during pregnancy is attracting considerable interest from researchers (Odacı et al., 2008, 2013, 2014; Topal et al., 2014). Studies on the subject have reported that exposure to the effect of EMF in the prenatal or postnatal period causes childhood leukemia (Wertheimer and Leeper, 1979), brain tumors in adults (Feychting et al., 1997), DNA damage (Lai and Singh, 2004), neurodegenerative diseases (Köktürk et al., 2013), immune system disorders (Kimata, 2004) and various cardiovascular diseases (Jeong et al., 2005; Hardell and Sage, 2008). Heart development in rats begins with the formation of the cardiogenic area on the ninth day of the prenatal term and continues, albeit at a low level, after birth (Marcela et al., 2012). "

    ABSTRACT: The growing spread of mobile phone use is raising concerns about the effect on human health of the electromagnetic field (EMF) these devices emit. The purpose of this study was to investigate the effects on rat pup heart tissue of prenatal exposure to a 900 megahertz (MHz) EMF. For this purpose, pregnant rats were divided into experimental and control groups. Experimental group rats were exposed to a 900 MHz EMF (1 h/d) on days 13-21 of pregnancy. Measurements were performed with rats inside the exposure box in order to determine the distribution of EMF intensity. Our measurements showed that pregnant experimental group rats were exposed to a mean electrical field intensity of 13.77 V/m inside the box (0.50 W/m(2)). This study continued with male rat pups obtained from both groups. Pups were sacrificed on postnatal day 21, and the heart tissues were extracted. Malondialdehyde, superoxide dismutase and catalase values were significantly higher in the experimental group rats, while glutathione values were lower. Light microscopy revealed irregularities in heart muscle fibers and apoptotic changes in the experimental group. Electron microscopy revealed crista loss and swelling in the mitochondria, degeneration in myofibrils and structural impairments in Z bands. Our study results suggest that exposure to EMF in the prenatal period causes oxidative stress and histopathological changes in male rat pup heart tissue.
