Because mobile phones and their base stations are two-way radios, they produce radio-frequency radiation (that's how they communicate), and they expose people near them to radio-frequency (RF) radiation. However, because both the phones and the base stations are low power (short range), the RF radiation exposure levels from them are generally very low.

New evidence is growing fast about health risks from the microwaves radiated by the mobile phones. It is the same type of radiation as in a microwave oven, although it is in much smaller doses.

Research studies in rats show that cells and the genes (DNA) will be affected and damaged by mobile phone radiation. In some experimental reports, mice exposed to mobile phone radiation over a period of time are found to have twice the risk of developing cancers, brain tumours and serious birth defects.

Evidence from human studies of mobile phone radiation shows a possible link with raised blood pressure and direct brain warming affecting brain function in heavy users. Like the microwave oven, the microwaves of the phone heat our human cells. Scientists have reported that these microwaves could directly damage the genes in cells. There is also increasing concern about children using mobile phones. Children are more sensitive to anything that affects their bodies. In fact, children absorb microwaves at three times higher the level than for an adult
