EFFECTS OF CELL PHONES ON HUMAN HEALTH -- 2

EFFECTS OF CELL PHONES ON HUMAN HEALTH By Vier Marqueses On 10 December 2013 In Features00000The cell phone is one of the greatest inventions created by man. Before, we only used the telephone, now we have the cell phone to use for communication on the go. However, like any other good thing, there is always something negative. There are potential health issues that come from frequent use of a cellular phone. Exposure to electromagnetic radiation is almost inevitable, now that mobile phones are everywhere. Even young children use phones. Some of us even sleep with our phones under our [url removed, login to view] the fact that there are negative effects on the nervous and reproductive systems, cell phones are still used [url removed, login to view], it is good that every day, mobile technology is changing. Then again, the exposure also changes, and we do not know whether it is good or [url removed, login to view] PhoneA cell phone is basically a type of radio. It is like a two-way walkie-talkie. Unlike the walkie-talkie, in which you either talk or listen, you can talk and listen at the same time. There are also other functions like a three-way call, call holding and voice [url removed, login to view] are two types of systems for cellular phones: Analog and digital. Older phones are considered analog while newer phones are [url removed, login to view] phones are cellular because they have a cellular system whenever calls take place. This is to ensure that the call is coming from a valid paying [url removed, login to view] Do Cell Phones Work?The invention of the mobile phone sprouted from the telephone, invented by Alexander Graham Bell in 1876. Wireless communication, meanwhile, is rooted to Nikolai Tesla’s radio in the 1880s. The two inventions were just combined to form what we know as the cell [url removed, login to view] cell phone works by transmitting to a base station at one frequency once a person makes a call. The signal then is transmitted to the main telephone network either through cables or radio link with a different frequency. Another base station will send the signal to the mobile phone of the person being called. Both cell phones transmit incoming and outgoing signals with different frequencies so that they won’t interfere with each other, unlike the walkie-talkie. The base stations continuously transmit the signals to both phones. Both phones will only transmit the radio waves until one phone cuts off the [url removed, login to view] Are People Exposed?The energy produced by mobile phones is very low. The energy is usually just 0.6 watts; five times lower than that of a flashlight. Whenever a person makes a call, signals are transmitted back and forth to the base station. Obviously, people are exposed to the radio waves from the [url removed, login to view] the cell phone tower antenna, the energy is released horizontally with some downward scatter. This energy decreases the farther it gets from the antenna. This makes the level of exposure to radio waves on the ground lower than the level near the [url removed, login to view] to radio waves coming from tower antennas is very unlikely, or at least minimal. The power levels are just too low and the placements of the antennas are high above ground level. Besides, signal transmission is sporadic, instead of [url removed, login to view] course, there are domestic cellular antennas that are mounted on rooftops. It is possible that people with such antennas get higher exposure. However, there are safety guidelines to follow and if the amount of energy released by the antenna goes beyond the limit, access to the area is [url removed, login to view] a mobile phone and a base station antenna, the latter produces more radio wave energy, with an amount comparable to a light bulb. Thanks to its position, the public is relatively safe from [url removed, login to view] phone signal is not the only exposure the public must be aware of. There is also a potential health risk when cell phones emit electromagnetic energy, which depends on the frequency of the phone. Frequency is the measure of waves of electromagnetic energy that pass in a given
