The mobile phone: friend or foe?
The use of mobile phones and other wireless communication are becoming an almost indispensable part of modern day life. However, the hand held devices have generated widespread controversy over whether they pose a risk to human health. The concern surrounds the risks associated with the radiation caused by the electromagnetic fields that the mobile phone emits.
Due to the proximity of a mobile phone to the head, and because the distance from the phone’s antenna to the inner ear is only a few centimetres, the auditory system is exposed to the electromagnetic radiation. The results of a study showed that a higher degree of hearing loss is associated with intensive use of mobile phones.
Various symptoms - memory or attention problems, tiredness, headaches, hearing problems - are sometimes reported. In some individuals these seem to correspond to a kind of 'electromagnetic hypersensitivity' attributable to the intense use of mobile phones or proximity to the transmitter masts which serve as their base stations.
Research on the possible health effects of exposure to radio frequency (RF) energy dates back more than 60 years and will continue for the foreseeable future. As research adds to the extensive scientific knowledge in this important area, it is believed that it will further strengthen the basis for public confidence in the safety of current and future wireless communications technologies.
One thing that I know for sure is that these signals gives awful headaches when you work in a wireless lab where three or four access points are broadcasting at the same time on different channels. I've also heard many stories about people who had their desk located directly under a broadcasting antenna and who had terrible migraines at the end of each day.
Here are a few recommendations to follow if you want remain on the safe side:1. LIMIT your usage of mobiles to the necessary minimum.
2. Don't stand in close proximity to any antenna that is transmitting. Those that are only made to receive signals are perfectly safe. If an antenna is a directional one, it is safe for you to stay in the back or
on the side of it.
3. Don't move a device that is transmitting.on the side of it.
4. Don't touch any powered antenna.
