In the earlier days, cellular phones were of brick size and they were usually attached to immobile surfaces such as cars etc. However, developments in technology, have led to the introduction of many pocket sized mobile phones. The mobile phone depends upon the use of radiations for its function. Since the whole world has been lured by this necessity, there is always a concern about the harmful effects of the radiations.

The harmful effects of the cell phone radiations were exposed in the year 1993. A case was reported in Florida, wherein a law suit was filed by a man, who claimed that his wife had been affected by brain tumour, because of the use of cell phone. It was only after such a case, that numerous researches have been conducted to find out if the cell phones really emit radiations that are harmful.

While some of the studies indicate that the microwaves emitted by the cell phones doubled the cancer cells in mice, the Cellular Telecommunications Association has spent so much on the research of the harmful radiations emitted by the cell phones. It still remains a controversy and it is still not proved whether cell phone radiations are harmful or not. The cell phones have been supposed to give out what is known as the Electromagnetic Radiations. As the phones are powered by electricity, they are believed to give out their electrical and magnetic fields. These radiations are emitted by other electronic goods such as microwave oven, electric clocks, computers and other such appliances. Such radiations come under the category of non ionizing radiations.

Non ionizing radiations are those which do not have the energy to cause ionization, which is they do not have the sufficient energy, to break apart molecules and atoms and turn them into ions. Ionizing radiations however, have high energy and they break apart molecules and atoms and turn them into ions. Examples of such harmful radiations are Gamma radiations and X-rays. When human cells are exposed to such harmful radiations, the DNA within the cells gets damaged, or their sequence gets changed resulting in mutations and birth defects. According to some research, the relation between the radiations and the effects of them on the users can be summarized as follows:

· The users of cell phone do not run a high risk of getting cancer than non users.

· Frequent users of cell phones do not have the risk of getting cancer or non malignant tumours, than those who use the phones rarely.

· It is a myth that brain tumours and cancers tend to develop on the side of the head, at which the phone has been used.

One of the observable harmful effects of mobile phones however has been the thermal effects. The microwave radiations cause dielectric heating. Here any dielectric material such as a living tissue gets heated up by rotation of polar molecules of the electromagnetic radiations. Therefore for the person who uses a cell phone, the heating will occur at the surface of the head.

As the subject by itself is controversial, the cell phones can be utilized judiciously and purposefully, as prevention is always better than cure.
