Are Mobile Phones Dangerous?

Introduction

I am looking at ‘Are mobile phones dangerous?’ The case study has some relevance to the current news topics because the findings have been made public and people are always asking ‘are there any risks’, as you will find out there are many theories and supposed evidence, that may or may not be reliable.                                                                                                        In this study I will be looking for a correlation between mobile phone usage and fertility in men, increased risk of brain tumours and other negative side effects such as concentration levels.

Background information: (information from http://www.vodafone.com.au/personal/aboutvodafone/healthmobilephonetechnology/howdoesthemobilephonesystemwork/index.htm )

Mobile phones use radio waves however some have a higher frequency so can be classed as microwaves. Radio waves are used for communication. Long wave radio has lengths of about 1km.Mobile telephones are two-way radios. When you talk into a mobile telephone, it picks up your voice and converts the sound to radiofrequency energy (or radio waves). The radio waves travel through the air until they reach a receiver at a nearby base station. The base station then sends your call through the telephone network until it reaches the person you are calling.image00.jpg

When you receive a call on your mobile phone, the message travels through the telephone network until it reaches a base station close to your phone. The base station then sends out radio waves that are detected by a receiver in your telephone, where the signals are changed back into voice or data.

  1. Scientists claim there is a considerable amount of evidence proving that microwave radiation from mobile phones causes brain tumours, slower brain function and other health problems. “A considerable body of evidence proves, beyond reasonable doubt, that microwave radiation from mobile phones and cordless phones causes a significantly increased risk for brain tumours, disturbed brain function, and other disturbances including damage to the genes”.  On the following website http://www.psrast.org/mobileng/mobilstarteng.htm#summary the conclusion is written in depth and also diagrams to back up the theory but also to show the effects.                                                                                                The theory coherently fits the other theories with a more detailed analysis. Although everything appears to fit, there is no information about the “scientists” who conducted the survey so how could you believe this with no first hand evidence?
  1. Children should be encouraged to limit exposure from mobile phones to their heads by reducing call time, by making calls where reception is good, by using hands-free devices or speaker options, or by texting. “Children have been warned to text rather than call, on their mobile phones by the federal government’s radiation safety watchdog”.                                This is due to the fact that children have softer growing skulls meaning more neurological damage would be inflicted as a pose to adults.                                        The website is http://www.

Conclusion

The website is http://www.independent.co.uk/life-style/health-and-families/health-news/cell-phones-are-safe-for-now-say-danish-researchers-1836100.html                                                         I think the source is quite reliable because the survey involved over 60,000 people.Researchers published the findings of the six-year £8.8 million Mobile Telecommunications and Health Research (MTHR) programme, which concluded there was no evidence that using a mobile for less than ten years was linked to brain cancer. “It also concluded mobile phone signals did not alter brain function and were not linked to cases of electrical hypersensitivity”.         The website is http://www.telegraph.co.uk/news/uknews/1562894/Mobile-phones-safe-in-the-short-term.html                                                                                 I think this source is reliable because by saying ‘in the short term’ is not denying long mobile phone usage will affect you, shows you that the source is honest. All they are saying is that they have not found a correlation between brain tumours and mobile phone usage in under eight years. A new study has provided further research to suggest that using a mobile phone does not increase the risk of brain cancer. “Japanese researchers found that regular mobile phone users were not at an increased risk of three types of brain cancer”.Participants included 322 brain cancer patients and 683 healthy people in Tokyo.                                                The website is http://www.inthenews.co.uk/news/health/mobile-phones-are-safe-$1197458.htm                                                                                         I think the source could be reliable because it informs the audience of both arguments to give them a better understanding and ultimately make their own decisions.

Here's what a teacher thought of this essay

3 star(s)

Overall the writing is of a good standard but some reformatting of the text and also the addition of footnotes would help with the flow of the essay. Also include discussion of difference between facts and opinions and how that may affect reliability of websites. A few more diagrams, perhaps of waves and maybe mobile phones may help.
