Electromagnetic Field (emf) Exposure

An Overview of electric caral Magnetic Field ( electromotive force ) Exposure and its Effects on HealthI . Introduction There is a recurring theme in fiction where radiation and electro magnetized painting due to unjustifiable , high-tech experiments gone wrong leads to mutation that could either form the exposed human into a superhero or a whale . In reality , EMF is much more planetary and part of daily life . Electro magnetised energy takes distinguishable forms , one of which is EMF . X-rays , visible light , atom-bombs and radio waves argon also electromagnetic energy forms . They are distinguished by their frequency . Some guiles produce more than one flesh of electromagnetic energy , such(prenominal) as a microwave oven , which produces 60 Hz of EMF and 2 .45 billion Hz of microwave energy . The term EMF is frequently employ to partake to galvanic and magnetic extend that are at passing low frequency (ELF ) range , in which the magnetic and electric sphere of influence do not interrelate as in high frequency EMF . ELF palm do not radiate , unlike EMF in the higher(prenominal) frequencies . These are called index number-frequency EMF ( Electric and magnetic field associated with the phthisis 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 electrical equipment and surrounds whatsoever object that uses electrical energy . The amount of EMF a device will emit depends on the voltage it uses which is economical in volts per meter (V /m ) or kilovolts per meter (kV /m ) and the incidental magnetic field produced by the flow of electricity done the device , measured in gauss (G ) or tesla (T .

Electrical fields are continuously produced even when the device is switched eat up unless it is baffled from a power source such as an freeing However , the focus of to the highest degree concerns is the effect of magnetic fields The EMF effect decreases as distance increases and maculation electrical fields are blocked by nonconductive materials such as trees , magnetic fields go through most materials . The EMF may also be depict in terms of its frequency , expressed in bicycle (Hz , which is the do of waves that pass per game . In North the States , the electricity from a regular household socket produces an alternating authorized with a frequency of 60 Hz , which means 60 waves per second ( Electric and magnetic fields as sociated with the use of electric power 1996EMF gets weaker as distance becomes greater Household appliances rattling hark back greater EMF than transmission lines because of law of proximity e .g a typical hairdryer 6 inches forth puts taboo 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 former(prenominal) and current research on health risks associated with EMF exposure at home and in the workplace , with specific care to the effects of overhead power line exposure and cellular or mobile phone use , and judicial proceeding concerning airscrew devaluation and personal...If you want to get a full essay, clubhouse it on our website: OrderCustomPaper.com
