 Mobile phone use concerns

Mobile phones emit high-frequency radiation, which is a type of non-ionising electromagnetic radiation. These waves can be absorbed through the soft tissues of the scalp and can penetrate the bone of the skull deeply enough to reach the brain but do so in varying amounts. The amount of radiation emitted by mobiles phones varies and is influenced to a number of factors.

Older mobile phones emit higher amounts of radiation than new handsets. This is due to the technology available for production at the time they were manufactured, which has been improved upon in more recent years. In addition, the closer you are to the antenna of the phone when using it greatly increases the chances that radiation could affect the tissue of the brain. This is further influenced by the way the phone is used. For example, people who use their mobile phones more often and for longer periods of time may be subjecting themselves to higher doses of radiation which can also be influenced by how close the person is to a mobile phone mast at the time of the call.

Research has been carried out in many studies to determine whether mobile phone radiation is damaging to human beings. However, nearly all of these studies have arrived at different conclusions, and no single paper has identified any direct link as of yet. There are a number of problems when carrying out research into this area. For example there is a recall bias, which means that if a person is asked how much they have used their mobile phone over the past year they may not be able to give a very accurate answer. Another problem is that people have often changed how they use their phones over the years - a person who used their mobile phone mainly for calls 10 years ago may now only use it for texting. In fact, it could be the case that the number of calls people make on mobile phones is decreasing while the number of texts sent each year and mobile internet use rise. Problems such as these make monitoring the harmful effects of mobile phones extremely difficult and lead to results that are inconclusive – a problem that current research is commonly afflicted by.

29. Mobile phone waves are always absorbed through the soft-tissue of the scalp

30. Older mobile phones produce more radiation

31. Being closer to the antenna of the mobile phone or close to the mobile phone mast increases the amount of radiation exposure

32. Many studies have been carried out into the harmful effects of mobile phone radiation

33. There are many problems facing researchers when trying to conduct research into mobile phone dangers

34. The radiation that mobile phones produce is ionising electromagnetic radiation

35. If a person was asked how much they used their phone they would not be able to remember

36. People use phones mainly for texting now

37. If you are using an old mobile phone you are less likely to receive radiation from it

38. Monitoring the harmful effects of mobile phones is problematic
