The number of mobile and wireless devices are growing rapidly e.g. in the UK there were 4.5 million mobile phones in 1995 as opposed to 50 million in 2000 and worldwide mobile phone sales increased from .43 million in 2002 to .51 million in 2003.  
Like all other radio communication applications, mobile phone technology uses radio waves to carry the information through the air. Radio waves are a kind of electromagnetic fields (EMF) that are also called radio frequency fields or radio frequency energy.  


Like all other radio communication applications, mobile telephony uses radio waves to carry the information, like voice, text and images, through the air. Radio waves are a kind of electromagnetic fields (EMF) that are also called radio frequency fields or radio frequency energy. Electromagnetic fields are present in our every day life, both naturally and from man-made sources.
When a person is exposed to the radio waves from mobile phones or base stations, most of the energy will be reflected by the body or travel around it. Some of the energy will however be absorbed in the tissues at the surface of the body.
Inside the body certain molecules, like water, will start to move or rotate due to the presence of the electromagnetic fields. By "friction" the energy is converted into heat. If the radio wave intensity is very high, the heating may be significant and potentially detrimental.

Since the introduction of mobile phones, there has been concerns over the possible health effects of these devices because of the emission of radiofrequency(RF) radiation. However the increasingly widespread use suggests that users are unaware of any possible health effects. In May 2000, the Independent Expert Group on Mobile Phones published a report that recommended a cautionary approach to the use of mobile phone technology until conclusive evidence could be found on any health effects. This recommendation was taken because scientific evidence suggested that there could be possible biological effects from the radiofrequency radiation even below the recommended level.
Since then there has been no hard evidence to suggest adverse health effects.

With the conflict in the Middle East, there has been growing concern over the availability of oil in the Middle East. Experts have also said that there is only another 40 years of crude oil left. Geologists are suggesting that global oil production could peak and decline steeply much sooner, increasing oil prices. Non-OPEC oil producing countries are already nearing peak production leaving most of the reserves in the unstable Middle East. Increasing tensions between Islam and the West will likely threaten access to affordable oil.
The mobile phone industry is fast growing and we are becoming more and more dependent on these technologies. However, use of this technology may possibly pose a health hazard. More and more research is going into this area because of the wide spread use of this technology especially among our children. Public awareness of the health issues surrounding devices that emit RF radiation is also growing.

Description:

Like all other radio communication applications, mobile phone technology uses radio waves to carry the information through the air. Radio waves are a kind of electromagnetic fields (EMF) that are also called radio frequency fields or radio frequency energy.

When a person is exposed to the radio waves from mobile phones or base stations, most of the energy will be reflected by the body or travel around it. Some of the energy will however be absorbed in the tissues at the surface of the body. Inside the body certain molecules, like water, will start to move or rotate due to the presence of the electromagnetic fields. By "friction" the energy is converted into heat. If the radio wave intensity is very high, the heating may be significant and potentially detrimental.

The specific absorption rate, SAR, is used to specify the amount of radio frequency energy absorbed in the body. SAR is expressed in the unit watts per kilogram (W/kg).
