A few words about SAR. Phone has body 0.62W/kg and head 0.75W/kg SAR levels.

Info from Carl (admin OPO forum) http://forums.oneplus.net/threads/on...1/#post-289699

I had no idea what this was so I googled it.

WHAT IS SAR AND WHAT IS ALL THE FUSS ABOUT?

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

SPECIFIC ABSORPTION RATE (SAR)

A SAR value is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person using a mobile phone, 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.

EXPOSURE LIMITS

In Europe, the European Council Recommendation 519/1999/EC for exposure guidelines has adopted the recommendations made by the International Commission on Non-Ionising Radiation Protection (ICNIRP Guidelines 1998). In the US, the FCC, Federal Communications Commission, sets the radio frequency safety guidelines that all phones must meet before being sold in the US. Current reference standards and limits (status January 2001).

As reference, I looked up the SAR of several phones... Samsung Galaxy SIII i535 (CDMA. VZW) had an overall rating of 1.29 US / 0.88 EU. Note the US and EU measure them differently. The US legal limit is 2.0. The source did not differentiate 'head' or 'body". source: http://sarshield.com/radiation-chart/
They're selling a radiation shield to help prevent exposure and it benefits them to provide lots of information - so take this with a grain of salt. It is very difficult to find comprehensive lists because the manufacturers would rather not have to publish this information. Lots of issues related to radiation exposure potentially causing brain cancer. Kind of like the cigarette manufacturers - smoking didn't cause cancer, no need to worry, nothing to see here, move along.

You make your own choices...
