Specific Absorption Rate (SAR) is a measurement of how much electromagnetic radiation is absorbed by body tissue whilst using a mobile phone. The higher SAR mean more radiation is absorbed by the body.
SAR limit is set to 2.0 W/kg in 10g of tissue, according to ICNIRP (International Commission on Non-Ionising Radiation Protection) guidelines recommendations which is adopted by the European Union Council and later endorsed by UK Government.
On the other hand, in the United States of America, the Cellular Telecommunications and Internet Association (CTIA) requires all cell phones to comply with the Federal Communications Commission (FCC) SAR limit of 1.6 W/kg in 1g of tissue.
When reviewing a mobile phone model, pay attention to it's SAR value.
Low SAR has it's own importance due to safety but mobile phone user can reduce exposure to phone radiation by following attitude given below:
Do not use the phone more than necessary and keep your calls shortPrefer a text (SMS) instead of making a callTry to avoid using your phone if the signal strength is low - find a better location to make a callTry to use the phone outdoors rather than inside, or move close to a window to make a callKeep the phone (and particularly the aerial) as far as possible from your headAvoid touching the aerial while the phone is turned on, and keep the phone away from body specially from eyes, testicles, breasts and internal organsLimit usage as much as possible if pregnantSwitch off the phone when not in useMake use of handfree (headphones)Abbreviations/acronyms Full Forms
