Specific Absorption rates for mobile phones.. worst players ..

Motorola, Blackberry, Sony Ericsson and Karbonn are the top offenders in terms of energy absorbed by human body from radio frequency electromagnetic field, measured in terms of Specific Absorption rate.

Specific Absorption Rate (SAR)  is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF)electromagnetic field; It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg).

http://en.wikipedia.org/wiki/Specific_absorption_rate  , this link tells us that most of the mobile phones are below the FCC recommended 2W/kg body mass upper energy absorption limit, though Motorola, Blackberry and Sony Ericsson are at SAR of 1.58 to 1.0, Nokia and Samsung are below 0.5 W/kg. Specific values of SAR, for different phones are given in the chart at the wikipedia link above, tested by approved vendors and put up for public scrutiny ..
