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. , Cardis E, Green A, Linet M, Savitz D, Swerdlow A. The physical quantity that is used in this context is the specific absorption rate (SAR), measured in W/kg. Department of Epidemiology, Institute of Environmental Medicine, Karolinska Institute, Stockholm, Sweden. , Cooper TG, Allen SG. The strongest evidence for health risks is from exposure to fields generated in connection with use of electric power. These case-control studies may also be affected by selection bias. For example, touching or standing around an antenna while a high-power transmitter is in operation can cause severe burns. Ahlbom More detailed data can in principle be obtained by using this approach. The studies that have used these data so far have limited themselves to basic data. , Chou C-K, Morgan R, Balzano Q, Guy AW, Funch DP, Preston-Martin S, Mandel J, Steffens R, Carlo G. Assessment of cellular telephone and other radio frequency exposure for epidemiologic research. [49][50], In the United States, nonionizing radiation is regulated in the Radiation Control for Health and Safety Act of 1968 and the Occupational Safety and Health Act of 1970. Seitz H, Stinner D, Eikmann Th, Herr C, Roosli M. (2005) Electromagnetic hypersensitivity (EHS) and subjective health complaints associated with electromagnetic fields of mobile phone communication---a literature review published between 2000 and 2004. RF radiation and ELF-EMF exposures are classified as a possible human carcinogen, Group 2B. This frequency band includes fields that are generated in connection with production, transmission, distribution and use of electric power. Examples are recommendations to use hands-free equipment and to limit calls as much as possible. “Microwaves, Radio Waves, and Other Types of Radiofrequency Radiation.” American Cancer Society, International Agency for Research on Cancer (IARC), Radiation Control for Health and Safety Act of 1968, Occupational Safety and Health Act of 1970, Biological effects of radiation on the epigenome, Central nervous system effects from radiation exposure during spaceflight, "15. 1. Normally this is converted to visible light by the phosphor film inside a protective coating. To date, half a dozen epidemiological studies on mobile phone users have been published—with predominantly negative findings. The National Institute of Environmental Health Sciences describes EMFs as invisible areas of energy, often referred to as radiation, that are associated with the use of electrical power and various forms of natural and man-made lighting. The initial lesions and edema will disappear after several weeks, but may leave behind a permanent reduction in visual acuity.[39]. , Loughlin JE, Funch DP, Dreyer NA. 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. C Adult and childhood leukemia near a high-power radio station in Rome, Italy. [25] 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. Environmental Pollution and Brain Development 6. 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. , Hemmings K, Saunders P. Re: Cancer incidence near radio and television transmitters in Great Britain. This technology typically uses frequencies from 450 up 2500 MHz, although new technology will extend this band upwards. 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. Electromagnetic radiation emitted by cell phone towers is a form of environmental pollution and is a new health hazard, especially to children and patients. Electromagnetic Fields and Breast Cancer. , Näsman Å, Påhlson A, Hallquist A, Hansson Mild K. Use of cellular telephones and the risk for brain tumours: A case-control study. 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. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. Due to potentially catastrophic losses and high clean up costs, product liability insurance contracts frequently exclude, whether partially or completely, the insured’s liability for asbestos, pollution and contamination, radiation and electromagnetic fields. , Yin Y, Morrell S.
