In 2010, over 5 billion people around the world are in ownership of a mobile phone. That’s around 60% of the world’s population; perhaps what is more astounding is that, this number is still growing.

When using a mobile phone, radiation is all directions is released, some even goes through you. This radiation is the same radiation as used in microwaves to cook and heat food. Admitted, the amount of radiation being released is small, but is it significant enough to actually harm us?

The aim of my case study is to decipher a definitive conclusion from a variety of information, statistics and theories from reliable sources. Once complete I hope to have a firm idea of, whether mobile phones are a risk to our health.

Commonly inside a mobile phone, you will find;

  • A circuit board.
  • A battery.
  • An aerial.
  • A microphone.
  • A loudspeaker.
  • A SIM card.
  • An LCD display.

These components are bound into, the often plastic structure of the phone.

Microwaves are a type of "electromagnetic" radiation.

Visible light is so common that molecules that are ionized by it will often react spontaneously, unless protected by materials that block the visible spectrum; examples include photographic film and some molecules involved in photosynthesis.

Ionizing radiation has a wide range practical uses, but it is also dangerous to human health.

Non-ionizing radiation refers to any type of electromagnetic radiation that does not carry enough energy to ionize atoms or molecules - that is, to completely remove an electron from an atom or molecule. (5)

Visible light, near ultraviolet, infrared, microwave and radio waves are all examples of non-ionizing radiation, though visible and near ultraviolet can also ionize some molecules. The light from the Sun that reaches the earth is largely composed of non-ionizing radiation, with the notable exception of some ultraviolet rays. However, most ionizing radiation is filtered out by the atmosphere.

Because it is lower energy radiation, the use of this type of radiation in medical fields and everyday life poses fewer health risks than ionizing radiation in forms such as X-ray’. (6)

Most scientific evidence has found that adverse reactions have found no short term effects but the long term effects are yet unknown for using mobile phones. (8)
