Excess mobile phone use- Health Issues……….

As a result of the enormous increase in mobile phone usage throughout the world the effect of mobile phone radiation on human health is the subject of recent interest and study,.

Part of the radio waves emitted by a mobile telephone handset are absorbed by the body. The rate at which energy is absorbed by the human body is measured by the Specific Absorption Rate (SAR), and its maximum levels for modern handsets have been set by governmental regulating agencies in many countries. In the USA, the Federal Communications Commission (FCC) has set a SAR limit of 1.6 W/kg, averaged over a volume of 1 gram of tissue, for the head. In Europe, the limit is 2 W/kg, averaged over a volume of 10 grams of tissue. It is worth noting that thermal radiation is not comparable to ionizing radiation in that it only increases the temperature in normal matter, it does not break molecular bonds or release electrons from their atoms.

Specific Absorption Rate

The specific absorption rate – or SAR as it is known – refers to the rate of electromagnetic energy that is absorbed by the human body when using cellphones and other devices emitting radio waves. It is measured in Watts per Kg of human tissue. If the SAR limit of cellphones is 1.6W/Kg (as in the US), the total time that a person can use cellphones is maximum 6 minutes. Given an error margin of 3, the total time a person can use cellphones translates to only 20 minutes per day.
