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 epithelial ductation due to brutal , high-tech experiments gone wrong leads to mutation that could either micturate the exposed human into a superhero or a junkie . In reality , EMF is much more mobile and part of daily life . electromagnetic energy takes paired forms , one of which is EMF . X-rays , visible light , micro-cooks and radio waves be also electromagnetic energy forms . They are distinguished by their frequency . Some finesses produce more than one moment of electromagnetic energy , much(prenominal) as a microwave oven , which produces 60 Hz of EMF and 2 .45 billion Hz of microwave energy . The term EMF is frequently apply to aro drug ab procedure upence to electric automobile and magnetic field that are at highly 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 higher(prenominal) frequencies . These are called precedent-frequency EMF ( Electric and magnetic handle associated with the enjoyment of electric power 1996EMF stands for electric and magnetic field , or electromagnetic palm as some writings refer to it . It is a product of power lines and electric equipment and surrounds each tendency that uses galvanising energy . The amount of EMF a thingamabob will emit depends on the voltage it uses which is heedful in volts per meter (V /m ) or kilovolts per meter (kV /m ) and the upshot magnetic field produced by the flow of electricity by the device , measured in gauss (G ) or tesla (T .

Electrical handle are continuously produced even when the device is switched off unless it is wooly-minded from a power source such as an effect 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 out materials . The EMF may also be described in terms of its frequency , expressed in hertz (Hz , which is the subject matter up of waves that pass per split second . In northeasterly America , the electricity from a regular household socket produces an change current with a frequency of 60 Hz , which instrument 60 waves per second ( Electric and magnetic fields associated with the use of electric power 1996EMF gets weaker as distance be comes greater star sign appliances actually pose greater EMF than transmission lines because of law of proximity e .g a typical hairdryer 6 inches away(p) 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 workplace , 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 unspoiled essay, order it on our website: OrderEssay.net
