Middle

Newer phones were invented, smaller in size. The next addition was the text feature. Since then there have been even more additions. Mobile Phones can connect to the Internet and act as cameras or mp3 players. Even video messaging is available. Practically every portable electronic device has been added as a feature, which comes with most mobile phones.image10.png

This has caused people to associate mobile phones with much more than just phone calls. People now expect phones to include features such as ‘Bluetooth’ and music players or camera’s.

Most teenagers and adults living in Britain today have their own mobile phone. People often talk to each other for long periods of time using these devices and there are theories that this common use of mobile phones can cause brain tumours.

Technology of Mobile Phones

When radiotelephones were used in cars, there was only one central antenna tower in each city and only about 25 channels available per tower. These phones needed powerful transmitters; they had to be able to transmit for about 70 km around. Also, the fact that there were only 25 channels meant that the new technology could not be widely used. Now, cellular technology allows each city to be split into cells, meaning that millions of people can talk on the phone at the same time.

Cell phones can be compared to walkie-talkies or CB radios to show how the technology differs. CB radios and walkie-talkies are half-duplex devices. This means that two people talking on a CB radio are using the same frequency so only one person can be speaking at a time. Mobile phones are full-duplex devices. This means that there is one frequency for talking and another for listening allowing two people to speak at the same time.

Conclusion

There are many arguments on both sides of the question. There are correlations showing a small link between mobile phone use after ten years and contracting a brain tumour. There is also evidence proving that mobile phone use on one side of the head more than the other can increase the risk of having a brain tumour, on the side of the head where a phone is mostly used. But there are limitations to these arguments. The current studies only show a small hint of a possible correlation after the phone has been used for ten years. It is thought that people with a brain tumour, when interviewed, will say that they used their phone most often on the side that they have the brain tumours. There is also the fact that there is no scientific evidence to explain why mobile phones radiation could be harmful. I believe that the benefits of mobile phones outweigh in currently known risks. I think that until further research is done, people should still be aware that there is a possibility of their mobile phones being harmful to them. I would encourage people to use their mobile phones to text rather than phone and to use a headset for calls if possible as this would reduce the amount of radiation absorbed into their head. Professor Johansen says, “We won't be able to make any firm conclusions on this issue until we can confirm these results with studies with more long-term and heavy cell-phone users.” [16] I think that people should bear this quote in mind and not cease mobile phones use entirely but attempt to use their phones in a safer way.
