There is considerable confusion and misunderstanding about the meaning of the maximum reported Specific Absorption Rate (SAR) values for cell phones (and other wireless devices). SAR is a measure of the rate of RF (radiofrequency) energy absorption by the body from the source being measured – in this case, a cell phone. SAR provides a straightforward means for measuring the RF exposure characteristics of cell phones to ensure that they are within the safety guidelines set by the FCC. Many people mistakenly assume that using a cell phone with a lower reported SAR value necessarily decreases a user’s exposure to RF emissions, or is somehow “safer” than using a cell phone with a high SAR value. While SAR values are an important tool in judging the maximum possible exposure to RF energy from a particular model of cell phone, a single SAR value does not provide sufficient information about the amount of RF exposure under typical usage conditions to reliably compare individual cell phone models. Rather, the SAR values collected by the FCC are intended only to ensure that the cell phone does not exceed the FCC’s maximum permissible exposure levels even when operating in conditions which result in the device’s highest possible – but not its typical - RF energy absorption for a user.

Specific Absorption Rate (SAR) values. To communicate with the network, mobile phones emit low levels of radio waves (also known as radiofrequency or 'RF' ... Variations in SAR do not mean that there are variations in safety.

nformation on Specific Absorption Rate (SAR) values To communicate with the network, mobile phones emit low levels of radio waves (also known as radiofrequency or 'RF' energy) when being used. Governments around the world have adopted comprehensive international safety guidelines, developed by independent scientific organizations, governing the exposure to RF energy. Mobile phones are designed to operate within these stringent limits. What is SAR? SAR stands for Specific Absorption Rate, which is the unit of measurement for the amount of RF energy absorbed by the body when using a mobile phone. The SAR is determined at the highest certified power level in laboratory conditions. However, the actual SAR level of the phone while operating can be well below this value. This is because the phone is designed to use the minimum power required to reach the network. Therefore, the closer you are to a base station, the more likely it is that the actual SAR level will be lower. Does a lower SAR mean that a phone is safer? No. Variations in SAR do not mean that there are variations in safety. While there may be differences in SAR levels among phone models, all mobile phones must meet RF exposure guidelines. How can I learn more about SAR and how it is measured? The EMF Explained website provides a detailed explanation of SAR, answers to commonly asked questions on the topic, as well as provides a short video clip that takes you inside a measurement laboratory to view the SAR testing process.

SAR (specific absorption rate) is an indication of the amount of radiation that is absorbed into a head while using a cellular phone, the higher the SAR rating the more radiation that is absorbed into the head.

SAR means Specific rate of absorption.i mean it will giev u an idea of how much ur body will be subjected to the radition when u talk on the phone .
