The Possible Links Between Cellphone Uses and Tumors

Decent Essays

1. How do cellphones work? These work by the signals which are transmitted to and can be received from the base station (usually located close by) through RF wave. RF wave is a type of electromagnetic wave with a frequency range of 300GHZ widely used in radio communication and in applications such as heating. RF waves along with FM waves, microwaves, visible light and heat come under non-ionizing radiation. RF does not cause cancer. These waves are different from radiations i.e. x-rays, gamma rays and UV rays. These radiations can destroy the chemical bonds that make up DNA (Deoxyribonucleic acid). At higher levels the RF waves can raise the temperature of the body. But the RF waves emitted by the cell phones are generally of lower energy level and hence it does not affect body temperature. 2. How are people exposed to RF waves? RF waves require more energy for long distance transmission. The energy at the transmitting antenna in cellphone will greater than the energy received by the receiving antenna of the cellphone (loss of energy during long distance transmission). When a customer communicates using cellphone which is in contact with their ear (either left or right) the maximum energy at the transmitting antenna of the cellphone during communication will be directly absorbed by that ear. The ear that is closest to the phone will absorb more energy that the ear that farther away. It also depends on factors such as: 1. Amount of time the cellphone is being used
