What is SAR?

SAR (Specific Absorption Rate) the speed at which electromagnetic power radiated from mobile handsets and towers is absorbed by the physical body.

SAR Value may be a measure of the utmost energy absorbed by a unit of mass of exposed tissue of an individual employing a mobile, over a given time or more simply the power absorbed per unit mass. SAR values are usually expressed in units of watts per kilogram (W/kg) in either 1g or 10g of tissue.

Every mobile model is tested for radio emission emissions. Using an internationally standardized method that meets government and regulatory requirements, a measurement is formed to work out what proportion of electromagnetic energy is absorbed by body tissue. This gives the SAR (specific absorption rate) value.

Governmental and regulatory agencies have established SAR limits under which telephone use has been determined by them to be safe.

The SAR limit in INDIA:

The Inter-Ministerial Committee on EMF Radiation found out by the Ministry of Communications and knowledge Technology had suggested stricter SAR limits (2 watts per kg) for mobile handsets.

While acknowledging the sensitivity of health-related effects of radiation emissions from mobile towers and therefore the recent concern raised by the planet Health Organization, the Indian Government has decided to line the new SAR limits to 1.6 watts per kg. This would make the Indian standards closer to the US standards prescribed by the FCC (Federal Communication Commission) where the permissible SAR levels are set at or below 1.6 watts per kg appropriated a volume containing a mass of 1 gram of tissue.

A high level of SAR is understood to possess ill effects on humans

How can the SAR value find out?

The SAR rating of every individual phone model is now being displayed on all mobile phones and on its packaging, which can enable users to form informed choices when purchasing a handset.

On your Smartphone dial *#07# to get the SAR value.

Sarvalues.com also brings this important information freed from charge to all or any cellular users and also provides useful links to other Websites containing information.

The easiest thanks to ascertaining SAR for several cellular phones is via the FCC's links to individual manufacturers' Web sites: http://www.fcc.gov/cgb/sar/. On On this page, you'll find links to most manufacturers' sites that include SAR information for his or her phones, alongside instructions on the way to search each site for SAR information.

Important user information: Features of phone models are sometimes revised or improved during production. This could cause a situation where an equivalent phone type appears to possess different SAR values. If so, please ask the user guide shipped together with your phone to ascertain the SAR value of your phone.

How can Exposure to Cell Phone Radiation be reduced?

The following tips will assist you to protect yourself from telephone radiation by enabling you to use your phone in ways in which lower your radiation exposure.

1. Use a speakerphone, earpiece, or headset to reduce proximity to the head (and thus exposure). While wired earpieces may conduct some energy to the top and wireless earpieces also emit a little amount of RF energy, both wired and wireless earpieces remove the best source of RF energy (the cell phone) from proximity to the top and thus can greatly reduce total exposure to the top.

2. Carry your telephone far away from your body—in a handbag, briefcase, or computer bag—not in your pocket where it's pressed up against you.

3. Increase the space between wireless devices and your body.

4. Consider texting instead of talking - but don’t text while you're driving.
