Mobile phones have revolutionized modern communication and empowered consumers and users. The advent, acceptance and proliferation of mobile phones has democratized opportunities and avenues for millions of people. Rural, hinterland and underserved areas are now interconnected to urban areas due to cellular communication technologies. However, like many consumer technology applications, mobile phones have their own distinctive disadvantages and advantages. Disadvantages Disadvantages include limited attention span to other activities and tasks while chatting incessantly on mobile phones, hazardous driving while conversing and being a slave to the crutches of this wireless communication gadget. Health Issues While there are many conflicting studies on the negative health effects of incessant mobile phone usage, male infertility, microwave radiation affect on the brain and irregular sleep patterns in pre-teens and teens have emerged as some of the major mobile phones usage related health issues. The Disadvantages of Mobile Phones Every coin has two faces. Same goes with the mobile technology. It has numerous advantages but it also brings with it some disadvantages. Effect on Health One of it is the radiations of mobile phones that are causing serious health hazards to the users. The mobile phone users are more prone
to brain tumors, ear defects, headaches and blurring of vision. The mobile phones use microwave radiations to transmit data or more clearly they use these radiations to connect. For this base stations are to be installed in various parts of the city so that effective coverage can be given to the users. These microwaves lead to serious health problems. it can cause the damage to the DNA, a causative factor for mutation in species, eye vision getting blurred and eye cancer, infertility, hyperactivity in new born children and different type of damages to the ear and tympanic membrane which can cause hearing defects in the individuals who excessively use mobile. Addiction in teenagers Due to low priced services in the form of postpaid and prepaid the teenagers can easily avail mobile telephony. Here the benefits get converted to disadvantages when the device is over used every time and at every place. The teenagers are talking of the services, giving and receiving text messages; downloading wallpapers and ringtones and playing games. They by this way get detached with the other important activities which are so important for their social and personality development. No personal life You keep it with you all the time and everywhere. You take it with you in an important meeting. You are discussing an important aspect of the budget for approval. At this point the mobile beeps and you get distracted from the important thing that you were discussing. Take another situation. You are on a vacation and relaxing on beach. Just then the mobile vibrates and when you receive
the call it is just another sales advertisement by the service company. It... Advantages The wireless communication function is the best advantage provided by a mobile phone. The ability to communicate via voice, text and even email has made anywhere, anytime human-to-human interaction possible across vast geographical areas. Emergencies Mobile phones can be used to give alerts or early warning alarms concerning various emergencies such as medical emergencies, weather-related disasters, accidents and crimes. Corporate Applications Industries, businesses and entrepreneurs have leveraged the new-age tools and applicationsbased capabilities of smart phones and other high-tech mobile phones.

A 50-minute call boosts activity in brain regions near the ear where a phone is located, a brainscanning study published February 22 in the Journal of the American Medical Association shows.
³This is the first paper that really shows there are changes in the brain,´ says bioengineer Henry Lai of the University of Washington in Seattle, who coauthored an editorial published in the same issue of JAMA. Talking on a cell phone pressed to the ear, he says, ³is not really safe.´ In the study, researchers measured the brain activity of 47 participants who had pairs of Samsung cell phones strapped to their heads, one on each side. The phone on the left ear was turned off, while the one on the right received a 50-minute recorded message. This phone was kept muted so that the subject didn¶t know which phone was on, and also to prevent stimulation of the brain¶s hearing center. A few minutes after the call, a PET scan revealed that brain regions next to the working phone had higher levels of glucose metabolism. The left side of the brain and other areas, even those quite close to the phone, showed no changes. Since active brain cells require glucose, the increase suggests that cell phone radiation is boosting brain activity. ³The human brain is sensitive to the electromagnetic radiation that is emitted from cell phones,´ says study coauthor Nora Volkow of the National Institute on Drug Abuse in Bethesda, Md. The particular brain regions affected would probably change depending on a phone¶s design and how a person held it, Volkow says. On the phones used in the study the antennas are near the bottom, so the brain areas involved were the orbitofrontal region, which sits right behind the eyes, and the temporal pole below it.
Glucose metabolism rose in these areas by about 7 percent²an increase typically seen when brain regions become active. For instance, glucose metabolism in the language centers of the brain rises by about 10 percent when a person is talking, Volkow says. The increase in brain metabolism observed in the experiment may be an underestimate, because cell phones emit more radiation when a person is talking, Lai says. Radiation levels also change depending on the phone type, the distance to the nearest cell phone tower and the number of people using phones in the same area. These variables have prevented scientists from getting good epidemiological evidence about potential health risks of cell phone usage. Researchers don¶t yet know whether cell phone radiation is dangerous. ³At this point we do not know what the clinical significance of this particular finding is,´ Volkow says. The heightened activity may not have any ill effects, or it may be dangerous, particularly with years of heavy cell phone use or in the developing brains of children and teens. ³In my case, I don¶t like my brain to be stimulated by anything that is not physiological,´ Volkow says. ³There are very easy solutions that don¶t cost anything for those who want to play it safe.´ For instance, people can limit their time on the phone, use the speakerphone option, or talk with a handsfree device that¶s connected to the phone with a wire.
A top brain cancer expert has warned that radiation from mobile phones is causing a huge increase in brain tumours. He says that the mobile-phone related health problems could kill far more people than smoking or asbestos and he's calling on the industry to reduce radiation exposure. He based his claims on growing evidence that using a mobile phone handsets "for 10 years or more can double the risk of brain cancer". While some studies have claimed that there is no risk, this report explains that many cancers take more than a decade to form, accounting for the seemingly few people who were effected by radiation.
Mobile phones could kill far more people than smoking or asbestos, a study by an awardwinning cancer expert has concluded. He says people should avoid using them wherever possible and that governments and the mobile phone industry must take "immediate steps" to reduce exposure to their radiation. The study, by Dr Vini Khurana, is the most devastating indictment yet published of the health risks. Related articles Phone-reliant Britons in the grip of 'nomophobia' Search the news archive for more stories It draws on growing evidence ± exclusively reported in the IoS in October ± that using handsets for 10 years or more can double the risk of brain cancer. Cancers take at least a
decade to develop, invalidating official safety assurances based on earlier studies which included few, if any, people who had used the phones for that long. Earlier this year, the French government warned against the use of mobile phones, especially by children. Germany also advises its people to minimise handset use, and the European Environment Agency has called for exposures to be reduced. Professor Khurana ± a top neurosurgeon who has received 14 awards over the past 16 years, has published more than three dozen scientific papers ± reviewed more than 100 studies on the effects of mobile phones. He has put the results on a brain surgery website, and a paper based on the research is currently being peer-reviewed for publication in a scientific journal. He admits that mobiles can save lives in emergencies, but concludes that "there is a significant and increasing body of evidence for a link between mobile phone usage and certain brain tumours". He believes this will be "definitively proven" in the next decade. Noting that malignant brain tumours represent "a life-ending diagnosis", he adds: "We are currently experiencing a reactively unchecked and dangerous situation." He fears that "unless the industry and governments take immediate and decisive steps", the incidence of malignant brain tumours and associated death rate will be observed to rise globally within a decade from now, by which time it may be far too late to intervene medically. "It is anticipated that this danger has far broader public health ramifications than asbestos and smoking," says Professor Khurana, who told the IoS his assessment is
partly based on the fact that three billion people now use the phones worldwide, three times as many as smoke. Smoking kills some five million worldwide each year, and exposure to asbestos is responsible for as many deaths in Britain as road accidents. Late last week, the Mobile Operators Association dismissed Khurana's study as "a selective discussion of scientific literature by one individual". It believes he "does not present a balanced analysis" of the published science, and "reaches opposite conclusions to the WHO and more than 30 other independent expert scientific reviews".
As the popularity of mobile phones is rising in one corner, reports of mobile phones depicting its ill effects are rising from the other corner. Brain experts warn people that mobile phones create a great risk for the cause of tumours and have asked all mobile phone industry to reduce the radiation that rise out of mobile phones. Hence, people are asked to avoid using mobile phones wherever possible. An award winning cancer expert has reported that mobile phones can cause more number of
deaths than smoking or asbestos. According to the report released by Dr. Vini Khurana, people who are using mobile phones continuously for 10 years are at a high risk of facing brain cancer. French government has warned about the usage of mobile phones by children too. It is also reported that Germany has asked its people to minimise the usage of mobile phones. Dr. Khurana has received 14 awards for the past 16 years and has also published numerous numbers of scientific papers especially on studies of the effects of mobile phones. He is of sure that there is a close relation between mobile phones and brain tumour and that it will be proved in the next ten years. He also adds that if the government does not take immediate steps and if the radiation is not reduced then there will be a rise in the death rates globally within a span of ten years and by then it would be too late to treat it medically. He also adds that about three billion people world wide are now using mobile phones which is actually more the number of smokers. Smoking results in the death of about three million people worldwide. As suggested by Dr. Khurana, industries dealing with mobile phones must see to that the radiation emitted from these devices is reduced. One can never stop using mobile phone just for this reason because the usage of mobile phones has grown to such an extent. Mobile phones have become a one stop device for almost all necessities. Therefore, instead of one avoiding the usage of mobile phones, proper precautionary measures can be taken by the mobile phone industries.
