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 magnetized exposure due to unfounded , high-tech experiments gone wrong leads to mutation that could either wreak the exposed human into a superhero or a goliath . In reality , EMF is much more terrene and part of daily life . Electromagnetic energy takes different 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 image of electromagnetic energy , such(prenominal) as a microwave , which produces 60 Hz of EMF and 2 .45 billion Hz of microwave energy . The term EMF is frequently employ to refer to electric and magnetic handle that are at extremely low frequency (ELF ) range , in which the magnetic and electric field do not interrelate as in high frequency EMF . ELF palm do not radiate , unlike EMF in the higher frequencies . These are called index number-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 literature refer to it . It is a product of power lines and electrical equipment and surrounds whatever object that uses electrical energy . The amount of EMF a device will emit depends on the voltage it uses which is thrifty in volts per meter (V /m ) or kilovolts per meter (kV /m ) and the incidental magnetic field produced by the flow of electricity through the device , measured in gauss (G ) or tesla (T .

Electrical fields are continuously produced even when the device is switched off 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 while electrical fields are blocked by nonconductive materials such as trees , magnetic fields go through most materials . The EMF may also be described in terms of its frequency , expressed in hertz (Hz , which is the do of waves that pass per game . In North America , the electricity from a regular household socket produces an alternating current with a frequency of 60 Hz , which means 60 waves per second ( Electric and magnetic fields associated with the use of electric power 1996EMF gets weaker as distance becomes greater Household appliances actually hark back greater EMF than transmission lines because of proximity e .g a typical hairdryer 6 inches away 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 former(prenominal) and current research on health risks associated with EMF exposure at home and in the workplace , with special care to the effects of overhead power line exposure and cellular or mobile phone use , and litigation concerning airscrew devaluation and personal...If you want to get a full essay, order it on our website: Ordercustompaper.com
