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 melodyation due to noncivilised , high-tech experiments gone wrong leads to mutation that could either collapse the exposed human into a superhero or a heavyweight . In reality , EMF is much more global and part of daily life . electromagnetic energy takes paired forms , one of which is EMF . X-rays , visible light , micro-cooks and radio waves ar also electromagnetic energy forms . They are distinguished by their frequency . Some finesses produce more than one impression of electromagnetic energy , much(prenominal) as a micro-cook , which produces 60 Hz of EMF and 2 .45 billion Hz of microwave energy . The term EMF is frequently apply t o bear upon to galvanising 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 higher(prenominal) frequencies . These are called precedent-frequency EMF ( Electric and magnetic handle associated with the intake of electric power 1996EMF stands for electric and magnetic field , or electromagnetic handle as some writings call to it . It is a product of power lines and electric equipment and surrounds each object lens that habits galvanizing energy . The amount of EMF a finesse will emit depends on the voltage it usances which is heedful in volts per meter (V /m ) or kilovolts per meter (kV /m ) and the nonessential 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 muddled from a power source much(prenominal) as an matter 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 almost materials . The EMF may also be described in terms of its frequency , expressed in hertz (Hz , which is the eye up of waves that pass per split second . In northwestward America , the electricity from a regular ho drillhold socket produces an vary current with a frequency of 60 Hz , which intend 60 waves per second ( Electric and magnetic fields associated with the use of electric power 19 96EMF gets weaker as distance becomes greater home plate appliances actually pose greater EMF than transmission lines because of proximity e .g a typical hairdryer 6 inches away(predicate) puts stunned 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 health risks associated with EMF exposure at home and in the oeuvre , 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 climb essay, order it on our website: BestEssayCheap.com
