Electromagnetic Spectrum- Are Mobile Phones Safe?
Momentarily, it is estimated that the number of worldwide mobile phone users exceeds 4.1 billion people. This signifies that the number of mobile phone users has quadrupled since 2002, when the number of mobile phone users was only 1 billion, and the increase is exponential (http://www.guardian.co.uk/). Unfortunately though, mobile phones are said to be provoking several health problems. With this radical increase mobile phone users, these health problems related to mobile phones exploit. What mobile phones do to provoke the several health problems is because they emit microwaves. Microwaves are an electromagnetic radiation with a frequency which ranges from 300 megahertz to 300 gigahertz, and has a wavelength which ranges from 1 nanometre to 1 meter (http://science.hq.nasa.gov). Mobile phones use microwaves, because they transmit the signals over great distances, and they are able to travel best through the environment. Mobile phones use microwaves because the parts that create the waves are small, therefore they are not space consuming, they don’t consume a lot of power, therefore they make the phone efficient to use, and they are a less dangerous type of wave as opposed to gamma rays or x-rays, which are other forms of radiation which can be used for telecommunication (http://naturalsociety.com/). Microwaves are set off from a mobile phone, every time a call is made, because that is when signals are to be transmitted. Every time one calls, the mobile phone is held closely to the head. Therefore the brain of the phone user is closely exposed to microwave radiation. Microwaves, just like any other form of electromagnetic radiation has an electric charge. Therefore a microwave radiation interacts with the dipole of a water molecule, due to the fact that the hydrogen is negatively charged and the oxygen molecule is positively charged. Therefore when microwave passes water molecules, due to wave propagation of the...
