Electricity substations take electricity from power lines and transformer lines to transform it from high to low voltage and distribute to the consumers. These substations generate low frequency electromagnetic fields similar to those emitted from over head power lines and electrical appliances at home. The present study is focused on assessing the potential bioeffects of Extremely Low Frequency Electromagnetic Fields (ELF-EMFs) on melatonin level and oxidative stress biomarkers, in subjects occupationally exposed to 132 kV high voltage substation in Hyderabad, India. These subjects are involved in maintenance and installation of power line distribution at electricity transmission network. The ELFEMFs exposed subjects (n = 142) included the electric utility workers, who were compared with age, and socioeconomic status matched controls (n = 151). The subjects were professionally categorized based on their job titles, with different exposure levels, as administrative workers (low exposure),
Workplace exposure to very low frequency electromagnetic fields may be linked to a doubling in risk of developing the most common form of motor neurone disease -- amyotrophic lateral sclerosis, or ALS for short -- suggests research published online in Occupational & Environmental Medicine.
Extremely low frequency electromagnetic field exposure during the initial three days post-surgery caused a significant increase in regeneration for both heads and tails, but especially tails. The first appearance of eyes occurred at day seven post-transection in exposed tail portions. In the sham exposure control tail samples the initial appearance of eyes occurred 48 h later. Concurrently, exposed heads and tails exhibited an elevation in the level of Hsp70 protein, an activation of an ERK cascade, and an increase in the SRF-SRE binding ...
All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and then reared for 60 days. The obtained results revealed that all growth indices were significantly (p | 0.05) improved by increasing in the EMFs intensity. 2 mT treatment indicated the highest final weight (43.95 ± 0.27 g), weight gain (6.83 ± 0.10 g), weight gain rate (20.94 ± 0.13 %), daily growth rate (0.38 ± 0.00 g day-1), specific growth rate (1.26 ± 0.01 % day-1) and the lowest food conversion ratio (p | 0.05). Survival rate had significantly (p | 0.05) increased in all exposed treatments compared to the control group. In conclusion, ELF-EMF can enhance the growth indices and survival rate of common

Radiofrequency electromagnetic fields are absorbed by the body and may subsequently provoke various effects. The strength of the energy absorption depends on the strength and the frequency of the electromagnetic fields, but also on the properties and structures of the biological tissue. Forces and heating due to radiofrequency electromagnetic fields are clearly proven and physically defined.

Analysis of literature, references to the experimental and theoretical research got possibility to disclose connections between health problems of population and long term expousure of low electromagnetic fields - electrosmog. The energy power of low frequency electromagnetic emission is quite small. But electromagnetic radiation of these frequencies has clearly expressed electric and magnetic fields influencing to the human body and individual organs. The most sensitive is central nervous and neuro endocrine systems. The main sources of electromagnetic fields in living and working environment are household appliance, electricity transmission, transformation and distribution devices. Electromagnetic fields emitted from electric devices propagating in the space under l/r³; l/r² and l/r regulations. It is typical for variation of values of electric and magnetic fields. The value of electromagnetic field parameters is defined by voltage of electric devices, current and positioning of studied ...
Exposure assessment is the determination or estimate of the magnitude, frequency of occurrence, and rate of exposure of an individual or a group to an environmental agent. The agents of interest in this case are the electric and magnetic fields (EMF) in the extreme low-frequency range that includes the power frequency of 50/60 Hz. There are an increasing concern that exposure to EMF may be associated with biological and health effects. This concern has prompted numerous measurement projects and the development of instrumentation, methodologies, and exposure models and simulations. This paper identifies the status of EMF exposure assessment research related to occupational exposures. It draws the recent results to emphasize the unique aspects of EMF exposures in the home and utilities environments, and highlights the research needs. The intensities of electromagnetic fields have been measured under power transmission and distribution lines, at substations and industrial plants and near various ...

The use of electromagnetic field in the treatment of diseases has already been known for centuries. Low hazard, wide applicability, good clinical effect and the relatively low cost enable the electromagnetic field therapy to be widely used. The biological effect of the electromagnetic field is based on inter alia, analgesic, anti-inflammatory, osteogenetic and regenerative actions, which are associated with the changes in cellular signal transmission, action on biological membranes, ion transport processes, protein synthesis, cell proliferation and apoptosis. In addition, the electromagnetic field increases quantity of collagen content elevating its density and a more regular arrangement. Furthermore, it induces the activation of glutathione peroxidase and intensification of the process of erythropoiesis leading to better use of oxygen in the tissues around the wound. The electromagnetic field is used in rehabilitation of patients with diseases of skeletal, nervous and respiratory systems. ...

Several studies have shown that low frequency electromagnetic field has biological and therapeutic potential on the human body, however, to very limited extent on the heart. In the current study cardiac patients suffering from exercise-induced-angina will undergo two consecutive stress tests, one test after being exposed for 30 minutes to the magnetic field and the other test after being exposed to placebo (magnetic field not operated). The order of which the magnet will be operated will be randomly assigned for the patients so a group of patients will be exposed to the magnetic field at their first stress test and another groups of patients will be exposed to the magnetic field at their second stress test. During resting period, and while the patients are subjected to the magnetic field, a 12 lead electrocardiogram (ECG) will be monitored. Thereafter the magnetic field and frequency will be turned off and the patients will be subjected to graded exercise stress test during which they will be ...
Purpose : A great deal of evidence has confirmed that electromagnetic fields can affect the central nervous system and are effective in gene expression as well as development, differentiation, cell proliferation, and apoptosis of embryonic neural cells.

Protein expressions of Pax6, Nestin, and cytokeratin 8/18 ...
And for all the civil servants - employed by various governmental authorities - to actively lure their own government and parliament must be regarded as very serious. I believe it is called high treason to engage in such an act, or…? I, as a scientist, am not here to promote convenience or economic growth, but only to serve and protect human health, as well as to directly protect other animals, plants, and bacteria. These aims must be my only target, not to ensure consumers nor parliaments there is no cause for alarm which would be a blatant lie.. ***. Based on earlier conclusions, the World Health Organization (WHO) in Geneva already in 2001/2002 classified powerfrequency magnetic fields as possibly carcinogenic for childhood leukemia (Class 2B), and, by May 31, 2011, radiofrequency electromagnetic fields were also classified as possibly carcinogenic for certain brain tumours (Class 2B).. In the same year, the Council of Europe said Ban mobile phones and wireless networks in schools, ...

Young adult long-term study: Beneficial cognitive effects of chronic EMF exposure were observed in both Tg and NT mice. EMF exposure had essentially no effect on oxidative markers in the hippocampus of Tg mice, and the changes in oxidative markers in NT mice can be interpreted as a decrease in oxidative stress. No effect of EMF exposure on any oxidative markers was observed in the cerebral cortex tissue of either NT or Tg mice. An increase in levels of soluble Aβ in both hippocampus and frontal cortex was detected in EMF-exposed Tg mice. Aged adult long-term study:No effect of EMF exposure on cognitive performance of cognitively impaired Tg mice was observed during the initial 5 months of EMF exposure, while NT mice showed improved performance on cognitive testing 5 months after exposure initiation. After 8 months of EMF exposure the cognitive performance of EMF-exposed Tg mice was considerably better. Exposed NT mice continued to show better cognitive performance compared to the control NT ...

A novel exposure system for double-blind human electromagnetic provocation studies has been developed that satisfies the precision, control of fields and potential artifacts, and provides the flexibility to investigate the response of hypotheses-driven electromagnetic field exposure schemes on brain function, ranging from extremely low frequency (ELF) to radio frequency (RF) fields. The system can provide the same exposure of the lateral cerebral cortex at two different RF frequencies (900 and 2140 MHz) but with different exposure levels at subcortical structures, and also allows uniform ELF magnetic field exposure of the brain. The RF modulation and ELF signal are obtained by a freely programmable arbitrary signal generator allowing a wide range of worst-case exposure scenarios to be simulated, including those caused by wireless devices. The maximum achievable RF exposure is larger than 60 W/kg peak spatial specific absorption rate averaged over 10 g of tissue. The maximum ELF magnetic field ...
A few studies concentrated on the effects of electrical (power frequency) electromagnetic fields (EMFs) on the human brain function and nervous system (Savitz et al., 1998; Hakansson et al., 2003, Feychting et al., 2003; Qiu et al., 2004). These studies clearly established that there is a strong and consistent relationship between exposure to electrical EMFs and various types of neurodegenerative diseases like Alzheimers disease, Parkinsons disease, motor neuron disease and amyotrophic lateral sclerosis (ALS) or Lou Gehrigs disease. ALS is also a type of motor neuron disease. The studies of Savitz, Hakansson and Feychting furnish ample evidence on the relationship between electrical EMF exposure and Alzheimers disease, while the study by Hakansson proves the relationship between exposure of electrical EMFs and ALS. Various other studies had also confirmed the link between electrical EMF exposure and ALS and Alzheimers disease (Johansen, 2000, 2001, 2004; Ahlbom, 2001; Park et al., ...
Microwave and other low frequency electromagnetic fields (EMFs) have been shown to act by activating voltage-gated calcium channels (VGCCs) with most biological effects being due to elevated intracellular calcium, consequent nitric oxide (NO) elevation and either peroxynitrite or NO signaling. This, the role of excessive intracellular calcium in microwave effects, the greater biological effects of pulsed fields and some 20,000 papers on microwave biological effects show that the current international safety standards do not predict biological hazard. Such standards are based on the false assumption that the predominant effects of microwave and other low frequency EMF exposures are due to heating. A whole series of biological changes reportedly produced by microwave exposures can now be explained in terms of this new paradigm of EMF action via VGCC activation, including: oxidative stress; single and double stranded breaks in cellular DNA; therapeutic effects; blood-brain barrier breakdown; ...

Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near 1/2 Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby computer monitor or TV set. For the latter, the image pulsing may be embedded in the program material, or it may be overlaid by modulating a video stream, either as an RF signal or as a video signal. The image displayed on a computer monitor may be pulsed effectively by a simple computer program. For certain monitors, pulsed electromagnetic fields capable of exciting sensory resonances in nearby subjects may be generated even as the displayed images are pulsed with subliminal intensity.. ...
Children are exposed to various kind of non-ionizan radiation in their daily life involuntarily. The potential sensitivity of developing organism to the effects of radiofrequency (RF) signals, the higher estimated specific absorption rate (SAR) values of children and greater lifetime cumulative risk raised the scientific interest for childrens vulnerability to electromagnetic fields (EMFs). In modern societies, children are being exposed to EMFs in very early ages. There are many researches in scientific literature investigating the alterations of biological parameters in living organisms after EMFs. Although the international guidelines did not report definite, convincing data about the causality, there are unignorable amount of studies indicating the increased risk of cancer, hematologic effects and cognitive impairment. Although they are less in amount; growing number of studies reveal the impacts on metabolism and endocrine function. Reproductive system and growth look like the most ...

Concern has arisen over human exposures to radio frequency electromagnetic radiation (RFEMR), including a recent report indicating that regular mobile phone use can negatively impact upon human semen quality. These effects would be particularly serious if the biological effects of RFEMR included the induction of DNA damage in male germ cells. In this study, mice were exposed to 900 MHz RFEMR at a specific absorption rate of approximately 90 mW/kg inside a waveguide for 7 days at 12 h per day. Following exposure, DNA damage to caudal epididymal spermatozoa was assessed by quantitative PCR (QPCR) as well as alkaline and pulsed-field gel electrophoresis. The treated mice were overtly normal and all assessment criteria, including sperm number, morphology and vitality were not significantly affected. Gel electrophoresis revealed no gross evidence of increased single- or double-DNA strand breakage in spermatozoa taken from treated animals. However, a detailed analysis of DNA integrity using QPCR ...

In this study we created a job-exposure matrix based on systematically performed magnetic field measurements in the 49 most common occupations among women in Stockholm County. We identified a group of occupations in which workers are exposed to higher than average magnetic field levels and spend a larger than average proportion of their time in high fields. Individual occupations showed large variation and overlap in measured magnetic field values. When exposure during 24 hours was taken into consideration the contrast between high and low exposure occupations was diluted but still discernible. Among the highest exposed were women working in kitchens and in shops, which comprises occupations that have not previously been identified as highly exposed to magnetic fields.. The main limitation of the study is the limited number of measurements in each occupation and that the subjects were all volunteers and thus not a random sample. To ensure representation the measurements were distributed within ...
This project will enhance knowledge in the area of electromagnetic fields and health by clarifying some of the actual effects of low frequency electromagnetic fields (LF-EMF) on the innate immune system. The main goal of this project is to gain a basic understanding of possible LF-EMF effects at all levels of the organism (molecular, cellular and whole organism). Our model builds on existing in vitro models studying the formation of oxygen radicals in human monocytes, thus taking into account past research and established effects.The research questions in theis proposal address how LF-EMF modulate a) the in vitro response of macrophages, b) in vivo fish health and c) transcription of (immune-relevant) genes. The animal species of choice is fish, common carp (Cyprinus carpio L.), using an in vitro culture system of the fish equivalent of human bone marrow-derived macrophages. Carp macrophages will be exposed to LF-EMF treatments to measure macrophage activation. Microarray analysis will be used ...

Sources of electromagnetic radiation. It is known that in the vicinity of a conductor through which the current flows electric and magnetic fields are generated simultaneously. If the current does not alternate in time, these fields do not depend on each other. In case of alternating current magnetic and electric fields are interconnected with each other, representing a uniform electromagnetic field. The electromagnetic field possesses certain energy and is characterized by electric and magnetic strength that is necessary to take into consideration when evaluating working conditions. Sources of electromagnetic radiation include: radio engineering and electronic devices, inductors, condensers of thermal installations, transformers, antennas, flange connections of wave-guide transmission lines, generators of ultra-high frequencies etc. Modern geodesic, astronomical, gravimetric, aerophotographic, marine geodesic, engineering-geodesic and geophysical works are carried out with use of devices ...

More studies that are focused on the bioeffects of radio-frequency (RF) electromagnetic radiation that is generated from the communication devices, but there were few reports with confirmed results about the bioeffects of RF radiation on reproductive cells. To explore the effects of 1950 MHz RF electromagnetic radiation (EMR) on mouse Leydig (TM3) cells. TM3 cells were irradiated or sham-irradiated continuously for 24 h by the specific absorption rate (SAR) 3 W/kg radiation. At 0, 1, 2, 3, 4, and 5 days after irradiation, cell proliferation was detected by cell counting kit-8 (CCK-8) method, cell cycle distribution, percentage of apoptosis, and cellular reactive oxygen species (ROS) were examined by flow cytometry, Testosterone level was measured using enzyme-linked immunosorbent assay (ELISA) assay, messenger ribonucleic acid (mRNA) expression level of steroidogenic acute regulatory protein (StAR) and P450scc in TM3 cells was detected by real-time polymerase chain reaction (PCR). After being irradiated
Using a custom build spectrophotometer equipped with Helmholtz coils and designed to study the effects of magnetic fields on enzyme reactions in real-time we have investigated the influence of fields, from 100 ?T to 10 mT and at a variety of field frequencies, on the membrane bound enzymes alkaline phosphatase and acetylcholinesterase. We have also employed other methods to apply a magnetic field, e.g. Biostim. In contrast to earlier reports we have been unable to detect any field effects on these enzymes under any field/frequency regime. We discuss possible reasons for the discrepancy between this and earlier work and note the particularly complex influence of small temperature changes that may confound analysis.. ...
We do not see the electromagnetic field, we vaguely knew what it was and therefore the danger seems to be mythical. However, unfortunately, the harmful effects of electromagnetic radiation on our health is difficult to overestimate. If we are talking about the child, the effect increases tenfold - there is a violation of the immune, nervous, cardiovascular, reproductive and endocrine systems. How to avoid and protect children?. We interviewed expert of the St. Petersburg center of hygiene and epidemiology «Control Kniazeva of Larisa.. - Larissa Viktorovna, what is the source of the electromagnetic fields.. - Sources of such radiation is in every apartment: electrical wiring, household electrical appliances (irons, vacuum cleaners, furnaces, TVs), cordless phones, computers and laptops etc All this creates a so-called household electrosmog. Also electromagnetic radiation enters the apartment from the outside: it is produced transformers, cell towers, television and radio towers, signal ...

The Appeal highlights WHOs conflicting positions about EMF risk. WHOs International Agency for Research on Cancer classified Radiofrequency radiation as a Group 2B Possible Carcinogen in 2011, and Extremely Low Frequency fields in 2001. Nonetheless, WHO continues to ignore its own agencys recommendations and favors guidelines recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). These guidelines, developed by a self-selected group of industry insiders, have long been criticized as non-protective ...
Controversy over cell phones in trains. A letter from T. Hondou in the Journal of the Physical Society of Japan has been widely reported in newspapers. Hondou claims that the simultaneous use of a number of mobile phones in an area with a reflective boundary, such as a commuter train, could create a level of exposure to electromagnetic fields that could exceed the guidelines of the International Commission on Non-Ionizing Radiation Protection. Other experts dispute his conclusions. Some have pointed out that the author used calculations suited to far-field exposure rather than Specific Absorption Rate - appropriate for near-field exposure. In addition, it has been claimed that he underestimated the dissipation of electromagnetic fields that would occur in a train with many people inside..

Electromagnetic radiation is the result of oscillating electric and magnetic fields. The wave of energy generated by such vibrations moves through space at the speed of light. And well it should... for visible light is indeed one form of electromagnetic (EM) radiation.. X-rays, radio waves, gamma rays, and infrared and ultraviolet light are the other main types of electromagnetic radiation. They are all traveling vibrations of electromagnetic waves, each with its own characteristic wavelength. Organized in order of wavelength, they make up the electromagnetic spectrum.. Sometimes it is useful to think about electromagnetic radiation as though it came in packets. These packets of EM radiation are called photons.. There is a second main type of radiation, which is the result of subatomic particles moving at very high speeds. That type of radiation is called particle radiation.. ...
Electromagnetic energy is the component that controls cell functions, therefore all bodily functions. When that energy is disrupted or taken away, your body is punished. The worry of harmful electromagnetic fields is widely known but PEMF therapy provides a safe, protective use of balancing frequencies to decrease the effects of negative electricity. Unlike magnetic frequencies, PEMF penetrates through the body at different strengths while not addicting the cells to require this energy. PEMF therapy is the best choice to help your body feel and work better so you can live your life to the fullest!. ...
There is disclosed a novel method and apparatus for generating high power electromagnetic radiation in the ultraviolet and visible regions of the electromagnetic spectrum wherein high energy electrons, produced by directing a lower frequency (radio to microwave) electromagnetic energy wave into a plasma producing medium (gas, vapor and mixtures thereof), are caused to collide with heavy particles of the medium to thereby cause same to be collisionally excited and subsequently emit electromagnetic radiation. Particular means are disclosed for coupling the lower frequency electromagnetic wave energy to the medium. In a preferred embodiment the medium is confined in a closed vessel or chamber at a selected pressure to which a magnetic field is applied to guide the high energy electrons to collision with said heavy particles.
Extensive Pulsed Electromagnetic Field research shows that PEMF therapy enables bone & connective tissue regeneration by enhancing growth & shortening rehabilitation.. Pulsed electromagnetic field therapy for bone stimulation & connective tissue regeneration is one of PEMFs first approved uses. PEMF therapy enhances regeneration of bone and connective tissue matrix. PERIOD. End of story. It ONLY fails where application parameters are faulty (or perhaps if someone has some sort of genetic anomaly).. Studies done that show no effect are red-herrings (poorly designed and meant to fail). PEMF have been repeatedly shown to reverse degenerative effects of osteoarthritis, rheumatoid arthritis and osteoporosis. The plethora of failures in the research can be largely-attributed to short duration PEMF application, or use of incorrect waveform, frequency, amplitude; or any combination of those.. We believe PEMF therapys effects on bone and connective tissue are at least partially attributable to MoreATP ...
http://www.emfnews.org/store/. Blue Tube Headset. Radiation Detector EMF Meter. Cell Phone Radiation Protection. (Brevard, NC) - For years, the issue of cell phone safety has been a hot topic of debate, but we now know, thanks to years of stringent laboratory research, that cell phones do emit levels of radiation that can negatively affect ones health.. Aulterra, the leading cell phone radiation neutralizer manufacturer, is introducing the new Aulterra Neutralizer™ into U.S. markets. The Neutralizer is a small holographic disc which has been scientifically proven to be significantly effective in reducing and neutralizing the harmful effects of electromagnetic waves.. Electromagnetic fields are all around us. In their natural form they are harmless. When electromagnetic fields are man-made, they have been shown to disrupt the DNA structure of our bodies, as scientific studies have demonstrated.. Growing evidence suggests that electromagnetic fields (EMF) can break or nick DNA strands. This ...
If carriers of electromagnetic force are photons, it also means that magnetic fields surrounding magnets are also composed of photons. I must confess that I am confused by this, especially as magnetic fields and its effects on matter do not show any similarity with light, which is a form of electromagnetic radiation, itself also made of photons. If both electromagnetic radiation and magnetic field are carried by photons, then why light doesn t cause a piece of iron to move around as magnetic field does. If it is made of photons, why photons of magnetic field don t excite electrons of atoms that they hit to higher energy level as photons of electromagnetic radiation do? Do photons comprising a magnetic field have a particular wavelength/frequency as photons of electromagnetic radiation do? Why are these same things, so strikingly different in their manifestations ...
An apparatus comprises a radio frequency magnetic field unit to generate a desired magnetic field. In one embodiment, the radio frequency magnetic field unit includes a first aperture that is substantially unobstructed and a second aperture contiguous to the first aperture. In an alternative embodiment, the radio frequency magnetic field unit includes a first side aperture, a second side aperture and one or more end apertures. In one embodiment of a method, a current element is removed from a radio frequency magnetic field unit to form a magnetic field unit having an aperture. In an alternative embodiment, two current elements located opposite from one another in a radio frequency magnetic field unit are removed to form a magnetic filed unit having a first side aperture and a second side aperture.
Mutat Res. 2012 Aug 30;747(1):138-41. Tempol suppresses micronuclei formation in astrocytes of newborn rats exposed to 50-Hz, 10-mT electromagnetic fields under bleomycin administration. Miyakoshi Y1, Kajihara C, Shimizu H, Yanagisawa H. 1Department of Public Health and Environmental Medicine, the Jikei University School of Medicine, Tokyo, Japan. Abstract A number of epidemiological studies have suggested that exposure to environmental and occupational electromagnetic fields (EMFs) contribute to the induction of brain tumors. The aim of this study was to investigate the mutagenetic effects of co-exposure to 50-Hz, 10-mT EMFs and bleomycin (BLM) using an ex vivo newborn rat astrocyte micronucleus assay. We also investigated whether the mutagenetic effects of EMFs were related to active oxygen species by using 4-hydroxy-2,2,6,6-tetramethyl piperidine-1-oxyl (tempol), a superoxide radical scavenger. Three-day-old male Sprague-Dawley rats were co-exposed to 50-Hz EMFs and BLM (5 or 10mg/kg body weight (BW)
Cell phones have only been in widespread use for a couple of decades, which is far too short a time for us to know conclusively whether or not using them could cause cancer. Research thus far appears to indicate that most of us have little if anything to worry about.. According to the federally funded National Cancer Institute, the low-frequency electromagnetic radiation that cell phones give off when we hold them up to our heads is non-ionizing, meaning it cannot cause significant human tissue heating or body temperature increases that could lead to direct damage to cellular DNA. By contrast, X-rays consist of high-frequency ionizing electromagnetic radiation and can lead to the kind of cellular damage resulting in cancer. Nonetheless, some cell phone users and researchers still worry about our cell phone usage, given how much we now use them and how little we know about their potential long-term effects.. The reason the issue keeps coming up is that some initial studies in Europe, where cell ...

This is an update of a Cochrane review first published in 2002. Osteoarthritis is a disease that affects the synovial joints, causing degeneration and destruction of hyaline cartilage and subchondral bone. Electromagnetic field therapy is currently used by physiotherapists and may promote growth and repair of bone and cartilage. It is based on principles of physics which include Wolffs law, the piezoelectric effect and the concept of streaming potentials. ...
PEMF therapy also affects the utilization of nutrients and other medications in the body. For example, PEMF therapy is contraindicated for patients who are under chemotherapy. This is because PEMF therapy promotes cell growth and repair, and so it may promote the proliferation of cancer cells. Therefore, PEMF therapy has effects that are antagonistic to chemotherapeutic drugs. These side effects can be avoided by starting PEMF therapy after chemotherapy has been completed. However, there is more research that is required in this area as some studies suggest that PEMF therapy actually helps chemotherapeutic drugs achieve their objective.. Although there is still much more research to be done, pregnant women are advised to avoid PEMF because it is considered to be a teratogen. A teratogen is an agent or factor that causes poor, abnormal or inhibited development of unborn babies or embryos. Therefore, pregnant women should not be exposed to PEMF since it increases the risk of miscarriage, birth ...
Using Survey Monkey (Palo Alto, CA), an online survey consisting of 13 questions was conducted in April 2012. Information about this on-going survey and the opportunity to participate was made available to all 27,000 students of the University of Innsbruck in Austria. A total of 2,013 students with a mean age of 24.5 years participated, with 66% of the respondents being female and 34% male. The students were from a wide variety of academic disciplines, and participation was anonymous and voluntary. The survey used parts of the original IARC [2011] press release as stimulus material. Participants were instructed to read the text from the original IARC press release: The WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer associated with wireless phone use. The IARC [2011] did not quantitate the risk; however, one study of ...

Are you concerned about how much cumulative exposure your kids have to electromagnetic radiation at home and at school from computers, cell phones, tablets, electronic toys, cell towers, power lines and the like?. If not, you should be! ...
Maxwells equations established that some charges and currents (sources) produce a local type of electromagnetic field near them that does not have the behaviour of EMR. Currents directly produce a magnetic field, but it is of a magnetic dipole type that dies out with distance from the current. In a similar manner, moving charges pushed apart in a conductor by a changing electrical potential (such as in an antenna) produce an electric dipole type electrical field, but this also declines with distance. These fields make up the near-field near the EMR source. Neither of these behaviours are responsible for EM radiation. Instead, they cause electromagnetic field behaviour that only efficiently transfers power to a receiver very close to the source, such as the magnetic induction inside a transformer, or the feedback behaviour that happens close to the coil of a metal detector. Typically, near-fields have a powerful effect on their own sources, causing an increased load (decreased electrical ...

We report the effects of pulsed electromagnetic fields (PEMFs) on the responsiveness of osteoclasts to cellular, hormonal, and ionic signals. Osteoclasts isolated from neonatal rat long bones were dispersed onto either slices of devitalised cortical bone (for the measurement of resorptive activity) or glass coverslips (for the determination of the cytosolic free Ca2+ concentration, [Ca2+]). Osteoclasts were also cocultured on bone with osteoblastlike, UMR-106 cells. Bone resorption was quantitated by scanning electron microscopy and computer-assisted morphometry. PEMF application to osteoblast-osteoclast cocultures for 18 hr resulted in a twofold stimulation of bone resorption. In contrast, resorption by isolated osteoclasts remained unchanged in the presence of PEMFs, suggesting that osteoblasts were necessary for the PEMF-induced resorption simulation seen in osteoblast-osteoclast cocultures. Furthermore, the potent inhibitory action of the hormone calcitonin on bone resorption was unaffected by PEMF

February 20, 2011. Thirty years ago, James Kinn with the U.S. Environmental Protection Agency (EPA) and Elliot Postow with Naval Medical R&D Command compiled a list of 3627 publications on the biological effects of electromagnetic radiation from 1 to 100 GHz. This 574 page document has been scanned and converted into a searchable pdf document that is available here. The references in this document are listed by title and author.. ABSTRACT. Considerable research effort has been made into the biological effects of electromagnetic radiation over the frequency range of 0-100 GHz. This work intensified since 1966 when occupational exposure guidelines were made by the American Standards Institute - C95.9. During this period and especially in the last several years it has become clear that a cumulative bibliography of peer reviewed publications reporting this research was needed.. This publication lists 3627 articles published in world literature dealing with the biological effects of electromagnetic ...
