Cell Phones Essays - Radiobiology, Mobile Telecommunications

Cell Phones What Causes Cell Phone Radiation and How Does it Effect Your Body? What is so popular with young teenagers today? Cell phones. Walking around on campus to walking around at the mall with your cell phone may seem fashionable and trendy, but did you now that it might be causing you to get a cancer? Ninety percent of cell phone holders do not realize it and it should be something everyone should be aware of. It may seem a bit unusually how a cell phone can cause a child or an adult to get cancer, but it is true. New evidence is growing fast about health risks from mobile phones ? electromagnetic radiation. These devices can be used to make telephone calls from almost anywhere. Symptoms such as fatigue, headaches, burning sensations on the skin were more common among those who make longer phone calls. At the same time there are a growing number of unconfirmed reports of individuals whose health has been affected after chronic, frequent use of mobile phones, presumably from radiation effects on cell. There are two types of phones, one has the antenna mounted on the handset and the other has the antenna mounted on a separate transmitter or, if the telephone is installed in a vehicle, mounted on the roof or rear window. Communication between a mobile telephone and the nearest base station is achieved by the microwave emissions from the antenna. Concerns have been raised about the type of mobile telephone that has the antenna in the handset. In this case, the antenna is very close to the user's head during normal use of the telephone and there is concern about the level of microwave emissions to which the brain is being exposed. Those telephones that have the antenna mounted elsewhere are of no concern, since exposure levels decrease rapidly with increasing distance from the antenna. Cordless telephones, which need to be operated within about 20 meters of a base unit that is connected directly to the telephone system do not have any health concerns associated with their use because exposure levels are very low. . Media reports have claimed that up to 70 percent of the microwave emissions from hand- held mobile telephones may be absorbed in the user's head. This is not supported by the evidence, but nevertheless leads to speculation that hot spots may be created in the user's brain, thereby raising concerns that the telephones may be a health risk. Other reports have indicated that mobile telephone users suffer localized headaches when they use their telephone. At this stage, it is difficult to evaluate the evidence supporting these reports, since they have not been published. This work on human subjects follows other phone studies in animals suggesting that radiation from mobiles may cause brain tumors, cancer, anxiety, memory loss and serious birth defects. An Australian study found that mice exposed to pulsed digital phone radiation over 18 months had twice the risk of developing cancers. An American study found that learning and short term memory were impaired after 45 minutes exposure to radiation from phones in rats. And other studies of electromagnetic radiation on pregnant mice suggest that high exposure can affect intra-uterine development, confirmed recently in chicks. The effects in humans are unknown. In Britain a 27 year old woman with a brain tumor is taking a mobile phone manufacturer to court who she blames for her tumor. A biologist, Roger Coghill has also been given permission to bring a case against a provider of mobile phone equipment for failing to warn people of radiation hazards. A wide variety of electrical devices contribute to electro smog, ranging from computers, to phones, TV sets, radar transmitter and transformers. However mobile phone radiation is certainly intense, as evidenced by the effects on aircraft navigation systems, or more obviously on a nearby conventional telephone or a music system The brain cancer reports originated in the USA where a number of lawsuits have been lodged against mobile telephone manufacturers and suppliers. These claims for damages allege that the microwave emissions from mobile telephones used by the claimants caused their brain cancers. Those few cases that have been tried have been dismissed for lack of supporting

Gun Control Will Not Prevent Violence essays

Gun Control Will Not Prevent Violence essays Gun Control Will Not Prevent Violence There is an outpouring cry for more gun control measures to prevent crimes and violence. However, throughout most of our history people have armed themselves for protection against criminals, invaders, and even abusive government. There are approximately four million new firearms - about two million being handguns - sold in the United States each year (8). The regulation of weapons and gun control laws will not solve the problem of violence and prevent crimes. Gun control laws do not work. Just the contrary, legitimate users of firearms submit to intense regulation, scrutiny, and bureaucratic control. Any effort to decrease the supply of firearms imposes damage on freedom and privacy that is fundamental to American life. The Brady bill, implemented in several states, requires a background-check and a five-day waiting period to acquire a handgun. The main accomplishment of this bill is the increase in hassle to the law-abiding citizen seeking a gun. Second Amendment scholar and attorney Stephen B. Halbrook debates the Second Amendment to the Constitution in his book That Every Man Be Armed. Halbrook states the Americans right to keep and bear arms grew out of political and philosophical tradition that dates back to the origins of Western Civilization. Halbrook notes as far back as Greek philosophers Plato and Aristotle, they shared the belief that an armed populace was essential for preventing the imposition of tyranny (7 12). It is arguable; the Second Amendment provides the right for everyone to bear arms, not just the militia. The principal justification for an armed populace was to secure the tranquility and good order of the community. In addition, Jim Babka, in his article Gun Control Only Seems Like a Good Idea!, he expounds on the 1982 Senate Subcommittee on the Constitutions confirmation that The Second Amendment is to provide protection of an indi...
