Cell Phones And Radiation

Cell phones and radiation - The debate on the radiation emitted by mobile phones has supporters on both sides and I do not think it will end anytime soon. Manufacturers have tried lately to reduce that level to reassure users. To better understand the problem, it doesn't hurt to know a few notions about radiation and the risks they present.
Many researchers argue that the radiation emitted by mobile phones cause health problems for users, because of the approach over the head. The fact that radiations affect the human body is not yet proven, but all experts are trying to convince us not to utilize extended mobile phones.
In the lines below you will learn more about this subject, such as radiation generated and how can you find the one delivered by mobile phone. Where do radiation occur? When you initiate a call, a receiver captures your voice and sends it to a mobile phone operator by means of an antenna of your device.
Mobile phones of today have power between 0.75 W and 1 W. the transmitter is located differently in each model separately, but usually is in the top. Electromagnetic radiation ranging from extremely low frequency to high frequency (gamma rays). Also, the head absorbs them very easily.
The effects of radiation on the human body. People are constantly studying the radiation emitted by mobile phones. In 1970, he said that children from such leukemia, but has turned out that there is no connection. Ionizing radiation is one type, atoms and molecules capable of destroying tissue, may even alter chemical reactions in the body. X-rays and Gamma are two examples in this regard. They are used in medicine, so they are not recommended for a patient to do more than one ray per year.
Ionizing radiation are emitted by the phones and there are not considered life-threatening. They have only the effect heaters, which do not affect any human tissue. Microwave ovens emit such radiation, but with a much higher power, up to 1000 W. Even if there was no apparent evidence that radiations are emitted by mobile phones they still are dangerous.
On the list of diseases and symptoms that might be influenced by the use of mobile phones are cancer, brain tumors, Alzheimer's, Parkinson's, increased fatigue, headaches. Cancer is actually the main disease on account of radiation in general, but could not prove any link.
Testing of mobile radiation. In the U.S. there are laws that prevent mobile marketing until each model passes the FCC test. These tests are made by the manufacturer. The radiation levels determine specific absorption rate (SAR), an indicator of past technical specifications of the phone. For a phone to pass FCC test, SAR must not exceed 1.6 W / kg).
The test is made using a mold that is shaped like a body, which is filled with a liquid that manages to simulate the electrical properties of human tissue. After this stage, a cell phone is held over the mold and using a mechanical arm is inserted into the liquid through a probe which reads the value of SAR in various locations. To pass the test value should be lower than 1.6 W/kg. The discussion about radiation risks will not end anytime soon, because neither party has very strong arguments.
