Effect of Radio Frequency Produced
by Mobile Phones
There is increasing concern about the risk of radio frequency emitted by cell phones, I argue that the radio frequency emitted by cell phones cannot damage human bodies in short term and people do not need to worry about the risk of cell phone radiation. Nowadays, mobile phone is a dominant component of modern telecommunications technology and it has become more and more popular and necessary in modern life. Nevertheless, the widespread use of mobile phones has given rise to a growing concern on the possible adverse health effects of the radiation they emit. Cell phones constitute the main source of radio frequency and electromagnetic fields exposure for human beings. Thus, more and more scholars and researchers try to figure out whether the radio frequency effects the human bodies or not. During the years of studies, the debate about the safety of cell phones never stops. Some scientists insist that the radio frequency emitted by cell phones can damage the human bodies, others oppose that there is no clear evidence which can prove the risk of cell phone radiation. The controversial claims stimulate more and more investigations and the eagerness of the truth. Meanwhile, lots of current studies provide us latest information and evidence that we cannot determine whether radio frequency can effect or damage human bodies such like brain tissue, DNA and blood lead.
What will make effect on us indeed by mobile phones? It is called radio frequency. Radio frequencies are simply another way to say radio waves. They are a natural consequence of wireless and electronic devices. Mobile phones are low-powered radio frequency transmitters, operating at frequencies between 450 and 2700 MHz with peak powers in the range of 0.1 to 2 watts. During normal mobile phone use, when operated at the head, some of the emitted RF EMF penetrates into the head tissues where it is...
