electromagnetic radiation environmental pollution and health
However, there remain gaps in the understanding of the biological effects, and more research needs to be performed. In 2009, the US TSA introduced full-body scanners as a primary screening modality in airport security, first as backscatter x-ray scanners, which the European Union banned in 2011 due to health and safety concerns, followed by Millimeter wave scanners . , Hallquist A, Hansson Mild K, Carlberg M, Påhlsson A, Lilja A. It is well known that exposure to strong fields can result in acute effects, such as burns; the mechanisms behind such effects are well established. For a variety of reasons, distance from the mast is a virtually meaningless proxy for exposure; thus, such studies cannot be designed in a meaningful way before meters or new exposure assessment models adapted to epidemiological purposes are constructed and made available. B
Interest has prevailed in relation to breast cancer, which remains a focus of attention.
Electromagnetic fields (EMF) are ubiquitous in modern society. 1 could be used to evaluate HERF, which states a maximum power density of 0.09 W/m² for frequencies under 225 MHz (i.e. RF radiation and ELF-EMF exposures are classified as a possible human carcinogen, Group 2B. Radiofrequency Electromagnetic Radiation and Health Impacts .

Although the results of the early occupational studies are mainly negative, they are of limited value in an overall assessment because of restrictions in their designs, particularly with regard to exposure assessment. Environmental Pollution and Brain Development 6. Sastre
Examples are recommendations to use hands-free equipment and to limit calls as much as possible. The results from this suggested that childhood cancer mortality was associated with the existence of power lines near the children’s homes, and particularly with such power lines that were indicative of high magnetic field exposure. Despite this, researchers have been intrigued by this possibility. This situation of scientific uncertainty and considerable public concern creates dilemmas for decision makers. Details in Bandara P and Carpenter D, … A new paper in the Lancet assesses the impact of Planetary Electromagnetic Pollution. Rothman
Taking a look at causes and effects of environmental pollution will pull any mind on a rapid downward spiral. The World Health Organization began a research effort in 1996 to study the health effects from the ever-increasing exposure of people to a diverse range of EMR sources. All high power transmitters. Handheld cellular telephone use and the risk of brain cancer. However, a recently completed large study with refined occupational exposure information and oestrogen status data for the cases was entirely negative and this is likely to affect the interest in this research track5. Hardell
That means that there "could be some risk" of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted. Tall, cellular antennas on school roofs will be a less common sight in Vancouver, BC, thanks to a groundbreaking decision by the Vancouver School Board (VSB). The actual field levels that people encounter in connection with mobile phone use produce SAR values below the basic restrictions, although of the same order of magnitude. However, according to the Environmental Literacy Council, ionized radiation that occurs from n… The present studies were taken to estimate the microwave/RF pollution by measuring radiation power densities near schools and hospitals of Chandigarh city in India. As a consequence, such fields essentially pass through the body without depositing any energy. The cell phone radiations were measured using a handheld portable power … ", Characterization of 60GHz Millimeter-Wave Focusing Beam for Living-Body Exposure Experiments, Tokyo Institute of Technology, Masaki KOUZAI et al., 2009, "Cutaneous effects of infrared radiation: from clinical observations to molecular response mechanisms", "Biological effects and medical applications of infrared radiation", "An Overview of the LED and Laser Classification System in EN 60825-1 and IEC 60825-1", "What is the minimum safe distance from the welding arc above which there is no risk of eye damage?

In essence, over the years, the childhood leukaemia results have increased in strength. There are, however, some as yet unconfirmed results that warrant further follow up. Electromagnetic fields are characterized by their frequency or wavelength; the wavelength is inversely proportional to the frequency. While the most acute exposures to harmful levels of electromagnetic radiation are immediately realized as burns, the health effects due to chronic or occupational exposure may not manifest effects for months or years. Health and electromagnetic fields EU-funded research into the impact of electromagnetic fields and mobile telephones on health KI-70-05-528-EN-C There is much public concern about the issues surrounding the eﬀ ects of electromagnetic ﬁ elds on health – in particular, the potential health eﬀ ects of mobile telephones.
, Photic retinopathy is damage to the macular area of the eye's retina that results from prolonged exposure to sunlight, particularly with dilated pupils. To date, close to 20 studies on childhood cancer and residential exposure to ELF fields have been published3. In parallel with the childhood cancer research, possible associations between other implicated diseases and ELF fields have been explored. To date, half a dozen epidemiological studies on mobile phone users have been published—with predominantly negative findings. Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on the capability of a single photon with more than 10 eV energy to ionize atoms or break chemical bonds. Electromagnetic smog in the workplace is an insidious form of pollution because it is not clearly perceived by people who may therefore find themselves exposed to high levels of radiation without realizing it. It is necessary for many plants to receive some form of non-ionizing radiation 3⭐⭐This is a verified and trusted source Goto Source . Environmental RF fields are characterized by their power density, measured as Watt per square metre (W/m2). Most of this research was directed towards other forms of cancer: brain tumours, leukaemia in adults, and male and female breast cancer are the forms that have attracted the greatest interest. . ICNIRP. For uncontrolled exposure to the general public, the limit is 180/f2 between 1.34–30 MHz. KJ
, Mezei G, Kavet R et al. Some fundamental problems with this approach are that the contract holder is not always the user of the phone and that additional information such as use of hands-free device is required for a more sophisticated assessment of exposure. However, whether, and by whom, even very low cost actions should be recommended in situations with such weak scientific support for the existence of a risk is currently the topic of intense discussions. , While the most acute exposures to harmful levels of electromagnetic radiation are immediately realized as burns, the health effects due to chronic or occupational exposure may not manifest effects for months or years. Hardell
The principal finding of the pooled analysis was that residential magnetic field exposure in excess of 0.4 μT was associated with about a doubling in the relative risk of childhood leukaemia.  Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation and radiation poisoning. IEGMP. Forssen
Thus, from the scientific view it makes more sense to study exposure from phones. Surveillances system of the type found in stores, as well as by cashier machines, often use so‐called intermediate frequencies, up to about 40 kHz. Sutton Coldfield transmitter. Cause-specific mortality in cellular telephone users. – discuss], Infrared wavelengths longer than 750 nm can produce changes in the lens of the eye. , Tarone RE, Hatch EE, Wilcosky TC, Shapiro WR, Selker RG, Fine HA, Black PM, Loeffler JS, Linet MS. Cellular-telephone use and brain tumors. All living tissues have magnetic properties that are affected to some extent by the existence of electromagnetic radiation in the environment. The next generation of studies may attempt to combine operator data and data obtained directly from the users. However, at a sufficiently high energy level, shortwave energy can be harmful to human health, potentially causing damage to biological tissues. Using operator data is, however, not a trivial approach from the logistic point of view. Some sources state that there is no minimum safe distance for exposure to these radiation emissions without adequate eye protection. Studies are being run to examine cells and determine if EM exposure can cause detrimental effects. Magnetic field exposure and cardiovascular disease mortality among electric utility workers. Utility of telephone company records for epidemiologic studies of cellular telephones. D
Occupational magnetic field exposure and cardiovascular mortality in a cohort of electric utility workers.  Focused RF radiation can also cause burns on the skin or cataracts to form in the eyes. United States Military Standard 464A (MIL-STD-464A) mandates assessment of HERO in a system, but USN document OD 30393 provides design principles and practices for controlling electromagnetic hazards to ordnance. For RF fields, the public health consequences would probably be large if a risk were to be detected. According to scientists, when the charged particles from the sun come in contact with the magnetic field of the Earth, they produce these lights. In parallel with the epidemiological research, extensive in vivo and in vitro research has also been carried out. As a consequence, the epidemiological evidence stands alone. Natural radiation is often beneficial to plant growth 3⭐⭐This is a verified and trusted source Goto Source . , Cardis E, Green A, Linet M, Savitz D, Swerdlow A. Radiation pollution refers to the increase in the natural radiation levels in our surroundings due to human activities. The evidence for other diseases seems instead to have decreased in strength over the years. J
, Boice JD, McLaughlin JK, Olsen JH. , The designation of mobile phone signals as "possibly carcinogenic to humans" by the World Health Organization (WHO) (e.g. , Feychting M, Möller M et al. The electromagnetic spectrum encompasses a wide variety of electromagnetic fields, including static fields, radio frequency fields, UV radiation, visible light and X-ray radiation. , Feychting M. Re: Use of cellular phones and the risk of brain tumours: a case-control study [letter]. Electromagnetic Radiation and the Reduction of Health Risks Theme: Healthy and Sustainable Cities The meeting will have the theme “Healthy and Sustainable Cities” and aims to provide visibility, disseminate knowledge and draw attention to the theme of Electromagnetic Pollution, ways of protecting and reducing risks to health and social vulnerability. Electromagnetic fields are ubiquitous in modern society. The low frequency band also includes fields that are used for communication with mobile telephony. RF exposure from base stations has also attracted attention, but this is to a great extent initiated by the public rather than by research interests. Is electromagnetic radiation really safe? Electromagnetic Fields and Breast Cancer. Claims are characterized by a "variety of non-specific symptoms, which afflicted individuals attribute to exposure to electromagnetic fields ". We declare no competing interests. This renders the study uninformative from the substantive point of view, although it has been important for methodological reasons15,16. To date, there are basically two types of studies on mobile phone users, which differ with respect to how exposure information is obtained. Overall the results are negative but because of the difficulties mentioned above, and because of some glimmers of associations in two studies, the issue cannot be settled yet14,24. Radio frequency radiation is found to have more thermal related effects. ", Since 1962, the microwave auditory effect or tinnitus has been shown from radio frequency exposure at levels below significant heating.
A person's body temperature can be raised which could result in death if exposed to high dosage of RF radiation. Epidemiological studies look for statistical correlations between EM exposure in the field and specific health effects. Adipose tissue (fat) receives little heating by induction fields because an electrical current is not actually going through the tissues. , Cooper TG, Allen SG.  The dielectric heating effect varies with the power and the frequency of the electromagnetic energy, as well as the distance to the source. Cancer incidence near radio and television transmitters in Great Britain. The internal SAR cannot be measured directly inside the body, but is established based on models and theoretical calculations. The Sun's radiation creates a photochemical reaction that can result in visual dazzling and a scotoma. NAVSEA OP 3565 Vol. Oxford University Press is a department of the University of Oxford. Review of the epidemiological literature on EMF and health. Thus, this is in essence a new research field. , In 2019 reporters from the Chicago Tribune tested the level of radiation from smartphones and found it to exceed safe levels. This can happen, for example, while observing a solar eclipse without suitable eye protection. Classification of electromagnetic … There is, however, also a concern that long-term exposure to weak fields might have health effects due to an as-yet unknown mechanism.
We will refer to these frequencies as ELF (extremely low frequency). N
To date, no adverse health effects have been established as being caused by mobile phone use. Typical maximum daily exposure to from man-made and natural radiofrequency electromagnetic radiation These exposure levels are frequently experienced daily by people using various wireless devices. Normally this is converted to visible light by the phosphor film inside a protective coating. A pooled analysis of magnetic fields and childhood leukaemia.  Short-term exposure can be beneficial (activating protective responses), while prolonged exposure can lead to photoaging. Later methodological studies have compared operator data and questionnaire data and showed that subjects systematically over-estimate the amount of phone use, which speaks in favour of using a combined approach23. 2019 Dec;117(6):648-655. doi: 10.1097/HP.0000000000001112. , Sunlight includes sufficient ultraviolet power to cause sunburn within hours of exposure, and the burn severity increases with the duration of exposure. L
The studies that have used these data so far have limited themselves to basic data. , Näsman Å, Påhlson A, Hallquist A, Hansson Mild K. Use of cellular telephones and the risk for brain tumours: A case-control study. Unlike the ELF area there is no seminal study with clear positive results that drives the research. P
It is well established that strong fields can give rise to acute health effects, such as burns, but exposure guidelines and regulations protect effectively against such effects.  These can deliver an electric shock to persons or animals. The current scientific situation is one of uncertainty and it is often pointed out that the existence of risks cannot be excluded. For example, the radio emissions from transmission lines have occasionally caused shocks to construction workers from nearby equipment, causing OSHA to establish standards for proper handling. So the decision maker would have to balance the public health benefits and the costs and technical and practical consequences of various schemes that could be considered in order to reduce exposure to the population. In particular, the studies by Hardell and co-workers have been criticized for the possibility of both selection bias and recall bias21,22. “Standard: Pollution, Asbestos, Electromagnetic fields. Yet, it is true that base stations give rise to whole body exposure for 24 h a day, for those who stay in the neighbourhood. EMF radiation is an ever increasing environmental pollutant. The first few of these replications addressed a variety of cancer types and also total cancer, but later studies have increasingly focused on childhood leukaemia. Existing exposure guidelines are expressed in terms of so-called basic restrictions and primarily aim to prevent neurological effects by restricting the internal current density2. KJ
All high power transmitters. Environmental Radiofrequency Electromagnetic Radiation (RF-EMR) has Skyrocketed! , Elliott P, Shaddick G, Walls P, Thakrar B. , Yin Y, Morrell S. Childhood incidence of acute lymphoblastic leukaemia and exposure to broadcast radiation in Sydney—a second look. Electromagnetic energy interacts with our bodies in powerful ways, and the effects of em radiation have profound and serious consequences for all life on our planet. To control the risk of injury, various specifications – for example ANSI Z136 in the US, EN 60825-1/A2 in Europe, and IEC 60825 internationally – define "classes" of lasers depending on their power and wavelength. This is why welders wear tinted glasses and surrounding workers only have to wear clear ones that filter UV.

Based on the combined control groups in the pooled analysis, this percentage was estimated at less than 1%, and considerably less in the European subset. Due to the widespread use of these techniques and the very prevalent exposure to some of the types of field involved, even a weak association with disease risk could have strong impacts on public health. Department of Epidemiology, Institute of Environmental Medicine, Karolinska Institute, Stockholm, Sweden. Photo : Alistair McIntyre, Pixabay. , Cook MR, Graham C. Nocturnal exposure to intermittent 60-Hz magnetic fields alters human cardiac rhythm. , EMR-induced sparks can ignite nearby flammable materials or gases, which can be especially hazardous in the vicinity of explosives or pyrotechnics. Johansen
In addition to sunlight, other sources include tanning beds, and bright desk lights. The evidence for the presence of health risks from RF fields is of course very weak, yet the existence of a risk cannot be excluded. This is most commonly the result of exposure to the sun at high altitude, and in areas where shorter wavelengths are readily reflected from bright surfaces, such as snow, water, and sand. Unpublished PhD Thesis. Electromagnetic pollution has effects on human health but is uncommonly considered in present times despite the fact we essentially expose ourselves to it on a daily basis.
As for fields used by telecommunications technology, there is still considerably fewer data available and for the time being there is only very weak support for the existence of health effects. Chances are you’re probably sitting in an electromagnetic field (EMF) at this very moment.

The electromagnetic spectrum can be divided into an ionizing and a non-ionizing segment. It is well known that exposure to strong fields can result in acute effects, such as burns; the mechanisms behind such effects are well established. Correspondence to: Anders Ahlbom, Professor of Epidemiology, Department of Epidemiology, Institute of Environmental Medicine, Karolinska Institute, Box 210, 171 77 Stockholm, Sweden. This risk is commonly referred to as Hazards of Electromagnetic Radiation to Ordnance (HERO) by the United States Navy (USN). Cataract-like changes can occur in workers who observe glowing masses of glass or iron without protective eyewear for prolonged periods over many years. Health Hazards Of Electromagnetic Radiation, 2Nd Edition: A Startling Look At The Effects Of Electropollution On Your Health , Ultraviolet light, specifically UV-B, has been shown to cause cataracts and there is some evidence that sunglasses worn at an early age can slow its development in later life. Have you ever seen the colorful patterns of the northern and southern lights? The SAR values that are indicated on some mobile phones are derived in this way and reflect the maximum SAR value that a particular phone is assumed to be able to produce. Despite intense efforts, this has not resulted in the detection of any new mechanisms of interaction between ELF fields and the human body beyond the induction of electric current, nor a strong candidate for such a mechanism.
Biology of Memory and Electromagnetic Field Radiation 7. While these fields differ with respect to strengths and physical characteristics, they all give rise to concern among those exposed about the possibility of health risks.
Indeed ELF fields were classified by IARC as a possible carcinogen; from the public health point of view, this classification often results in the agent being considered carcinogenic. The current density induced in the body is a direct consequence of the external magnetic field flux density; this is the reason why such fields are typically characterized by their μT-level. Ahlbom
The exception is certain work places where high electric fields can momentarily result in current densities near the guideline reference values. These are exactly the kind of burns that would be caused inside a microwave oven.
This research area is still in a very premature state and the results of the published studies are of limited interest. Electromagnetic Disharmony On The Earth. Temperatures in muscles can increase by 4–6 °C, and subcutaneous fat by 15 °C. There is, however, also a concern that long-term exposure to weak fields might have health effects due to an as-yet unknown mechanism. , Schulman J, Merrill DW. The purpose of the basic restrictions in existing guidelines is to prevent excessive heating, locally or in the whole body2. How mangrove plants affect microplastic distribution in sediments of coastal wetlands: Case study in Shenzhen Bay, South China.  Most UV light from the sun is filtered out by the atmosphere and consequently airline pilots often have high rates of cataracts because of the increased levels of UV radiation in the upper atmosphere. Epidemiologic evidence on health risks of cellular telephones. Health Hazards Of Electromagnetic Radiation, 2Nd Edition: A Startling Look At The Effects Of Electropollution On Your Health [Fife, Bruce] on Amazon.com. Electromagnetic waves at low frequencies are referred to as electromagnetic fields and those at very high frequencies are called electromagnetic radiations 1,2).
air at 3.0 MV/m). Electromagnetic hypersensitivity ( EHS) is a claimed sensitivity to electromagnetic fields, to which negative symptoms are attributed. H
Electromagnetic radiation can exert an aversive behavioral response in rats, bats and birds such as sparrows. The last quarter of the twentieth century saw a dramatic increase in the number of devices emitting non-ionizing radiation in all segments of society, which resulted in an elevation of health concerns by researchers and clinicians, and an associated interest in government regulation for safety purposes. Practically every new invention adds something to electromagnetic radiation pollution.
Given the small amount of energy that is deposited in connection with exposure to ELF fields, any health effects due to weak long-term exposure would have to be produced by a to-date unknown biophysical mechanism. At the lower end of the electromagnetic spectrum, it is customary to refer to the frequency, while at the upper end one usually uses wavelength. A
Ahlbom et al3 give a comprehensive overview of the relevant epidemiology. being influenced to a great degree by electromagnetic pollution. The only known consequence of this is heating. Radioactive materials are those materials or elements that emit radiation, thus they are not stable and get transformed into other radioactive or non-radioactive materials. Is Wireless Technology an Environmental Health Risk? These experiments were followed by a utility worker study showing that chronic heart disease mortality was not associated with ELF exposure but that arrhythmia and myocardial infarction mortality was7. S
, Exposing skin to infrared radiation near visible light (IR-A) leads to increased production of free radicals. Autism Spectrum Disorder and Electromagnetic Field Radiation 8. Comprehensive research efforts are therefore warranted, and are indeed ongoing. It is said that in today’s world about 20% of radiation we are exposed to is due to human activities. Although the implications by many were considered implausible, and despite several methodological problems in the study, that work has been followed by several attempts to replicate the findings. Yet, there are some risk management actions that could be invoked at low cost. As with its infrared and ultraviolet radiation dangers, welding creates an intense brightness in the visible light spectrum, which may cause temporary flash blindness. All these studies have focused on brain tumours although some have looked at other intracranial tumours as well. This frequency band includes fields that are generated in connection with production, transmission, distribution and use of electric power.  The FCC limits for maximum permissible workplace exposure to shortwave radio frequency energy in the range of 3–30 MHz has a plane-wave equivalent power density of (900/f2) mW/cm2 where f is the frequency in MHz, and 100 mW/cm2 from 0.3–3.0 MHz. Now it’s too late. DR
In an evaluation of carcinogenicity, IARC (The International Agency for Research on Cancer) classified ELF magnetic fields as 2B, which translates to possible carcinogen; the basis for this classification was the childhood leukaemia results. Cell phone radiation exposure emf neutralizer qlink golf air filled wireless tube headset elf radiating devices appliances cell phone towers health risks cell. *FREE* shipping on qualifying offers. Electromagnetic radiation is perhaps the most serious form of environmental pollution we face in modern times.  Likewise WiGig for personal area networks have opened the 60 GHz and above microwave band to SAR exposure regulations. Savitz
It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Because of the already widespread exposure, even small health effects could have profound public health implications. The purpose of this report is to create awareness elements of the environment.
Use of electricity and telecommunications are the technologies that have caused most of the current concern regarding possible health risks and for which most research is available. , This article is about the health effects of non-ionizing radiation. , Capon A, Kirchmayer U, Forastiere F, Biggeri A, Barca A, Perucci CA. Sources … This technology typically uses frequencies from 450 up 2500 MHz, although new technology will extend this band upwards.  It is hypothesized that depletion of the ozone layer and a consequent increase in levels of UV light on the ground may increase future rates of cataracts. , Gordon IR, Grain HL, Hatfield GE. They occur in connection with use of electric power, electronic surveillance systems and various types of wireless communications.
