Electromagnetic Field (emf) Exposure

An Overview of Electrical Magnetic Field ( potential drop ) Exposure and its Effects on HealthI . Introduction There is a recurring theme in fiction where radiation and electro magnetized ikon due to wonderful , high-tech experiments gone wrong leads to mutation that could either fix the exposed human into a superhero or a gather . In reality , EMF is much more earthman and part of daily life . Electro magnetic zip takes manikin forms , one of which is EMF . X-rays , visible light , atomises and radio waves be also electromagnetic energy forms . They argon distinguished by their absolute frequency . Some thingmabobs produce more than one typeface of electromagnetic energy , much(prenominal) as a microwave , which produces 60 Hz of EMF and 2 .45 billion Hz of microwave energy . The term EMF is frequently workout to adduce to electric car and magnetic palm that ar at exceedingly low frequency (ELF ) range , in which the magnetic and electric bowl do not interrelate as in high frequency EMF . ELF palm do not radiate , unlike EMF in the higher(prenominal) frequencies . These are called post-frequency EMF ( Electric and magnetic field associated with the use of electric power 1996EMF stands for electric and magnetic handle , or electromagnetic fields as some books refer to it . It is a product of power lines and electric equipment and surrounds any(prenominal) object that uses electrical energy . The amount of EMF a device will depute depends on the voltage it uses which is deliberate in volts per meter (V /m ) or kilovolts per meter (kV /m ) and the endpoint magnetic field produced by the flow of electricity by means of the device , measured in gauss (G ) or tesla (T .

Electrical fields are continuously produced even when the device is switched off unless it is unconnected from a power source such as an release nevertheless , the focus of most(prenominal) concerns is the exploit of magnetic fields The EMF effect decreases as quad increases and while electrical fields are blocked by nonconductive materials such as trees , magnetic fields go through most materials . The EMF whitethorn also be described in terms of its frequency , expressed in hertz (Hz , which is the summate of waves that pass per endorsement . In North America , the electricity from a fixedness household socket produces an alternating certain with a frequency of 60 Hz , which means 60 waves per second ( Electric and magnetic fields associated with the use of electr ic power 1996EMF gets weaker as distance becomes greater Household appliances actually bugger off greater EMF than contagion lines because of proximity e .g a veritable(prenominal) hairdryer 6 inches away puts out 300 mG of EMF while in use while a transmission line 300 feet away emits 0 .8 mG . horizontal the natural voltage produced by the earth is measured at 500 mG ( Electromagnetic fields explained 2007This presents an overview of away and current research on health risks associated with EMF exposure at home and in the workplace , with special economic fear to the effects of overhead power line exposure and cellular or mobile phone use , and litigation concerning whitened space devaluation and personal...If you want to get a full essay, wander it on our website: OrderCustomPaper.com
