Electromagnetic Field (emf) Exposure

An Overview of Electrical Magnetic Field (EMF ) Exposure and its Effects on HealthI . Introduction There is a recurring theme in fiction where radiation and electro magnetised de line of creditation due to roughshod , high-tech experiments gone wrong leads to mutation that could either prep are the exposed human into a superhero or a goliath . In reality , EMF is much more mundane and part of daily life . electromagnetic energy takes frigid forms , one of which is EMF . X-rays , visible light , micro-cooks and radio waves are also electromagnetic energy forms . They are distinguished by their frequency . Some finesses produce more than one subject of electromagnetic energy , much(prenominal) as a nuke , which produces 60 Hz of EMF and 2 .45 billion Hz of microwave energy . The term EMF is frequently apply to inte rest to electric and magnetic field that are at exceedingly low frequency (ELF ) range , in which the magnetic and electric field do not interrelate as in high frequency EMF . ELF field do not radiate , unlike EMF in the high frequencies . These are called precedent-frequency EMF ( Electric and magnetic handle associated with the accustom of electric power 1996EMF stands for electric and magnetic field , or electromagnetic field as some writings touch on to it . It is a product of power lines and electric equipment and surrounds each endeavor that drops electrical energy . The amount of EMF a spin will emit depends on the voltage it habits which is heedful in volts per meter (V /m ) or kilovolts per meter (kV /m ) and the sequel magnetic field produced by the flow of electricity by the device , measured in gauss (G ) or tesla (T .

Electrical palm are continuously produced even when the device is switched off unless it is confounded from a power source much(prenominal) as an young However , the focus of nigh concerns is the effect of magnetic fields The EMF effect decreases as distance increases and while electrical fields are blocked by nonconductive materials such as trees , magnetic fields go through ab let on materials . The EMF may also be described in terms of its frequency , expressed in hertz (Hz , which is the labor union up of waves that pass per split second . In uniting America , the electricity from a regular ho practicehold socket produces an alternate current with a frequency of 60 Hz , which path 60 waves per second ( Electric and magnetic fields associated with the use of electric power 1996EMF gets weaker as distance becomes greater theatre appliances actuall y pose greater EMF than transmission lines because of proximity e .g a typical hairdryer 6 inches by puts out 300 mG of EMF while in use while a transmission line 300 feet away emits 0 .8 mG . Even the natural voltage produced by the earth is measured at 500 mG ( Electromagnetic fields explained 2007This presents an overview of recent and current research on wellness risks associated with EMF exposure at home and in the body of work , with special precaution to the effects of overhead power line exposure and cellular or mobile phone use , and litigation concerning position devaluation and personal...If you want to get a abundant essay, order it on our website: OrderEssay.net
