1.1 Watts per kilogram refers to total absorbed RF energy over time resulting in heat, which does not equal RF power?
Watts is power, Joules is energy. Watts per kilogram is a power density measurement. Subtract the power dissipation, multiply by time, and divide by specific heat to get the temperature change.
The SAR limit is 1.6W/kg averaged over 1g of tissue (presumably mostly water).
The electromagnetic radiation emanating from your iPhone is a minuscule fraction of the radiation dose you get by stepping into the sunshine, or from that broadcast TV antenna down the block from your apartment, which is belting out EM waves measured in megawatts. Your phone will not kill you or give you cancer or scramble your brain - all urban legends.
Why do people think that if they don’t understand something, it must be wrong?
I’m not sure if you’re being sarcastic and I’m being gullible, but it sounds like you think your logic leads to your conclusion.
First, the sunshine isn't really much stronger than the SAR limit and it can be quite harmful— not because of the ionizing effects of UV, but because of the thermal loading causing various organs to malfunction (ie. heat stroke) with only a few degrees of internal temperature rise.
That's not the real comparable here though. SAR testing is less worried about raising your body temp and more worried about overheating sensitive tissues. Heat stroke is relatively uncommon because our bodies try to regulate their internal temperature and sweat to evaporatively cool-- we mostly get into trouble when those systems fail.
SAR testing is more worried about tissue that doesn't dissipate heat well-- like your eyes. There's a reason why we don't worry too much about going out in the sun, but all know not to stare at it. It's because that same radiation source that our backs and bellies can absorb just fine can be quite damaging to our eyes even after fairly brief exposure-- our eyes don't dissipate heat well, and staring at the sun cooks them.
The sun at noon is about 1kW per square meter. In broad daylight, our pupils are about 2mm in diameter-- so our eyes admit about 1e3*π*0.001^2= about 3mW. About half of that light makes it to the retina, or about 1.5mW. That's not much different than the 1.6mW averaged over a gram of tissue and it will cause significant eye damage.
Your eye won't detect radio and remind you to look away. Since it's the reactive magnetic near field, your eyelid won't block it.
The megawatt TV tower at the end of your block has lower power densities than the sunlight just discussed when you're 9 meters away from it (Surface area of a sphere of radius 9m is approx 1000 square meters, one megawatt distributed over a 1000 square meters is 1kW/square meter).
And again, the TV tower is predominantly electric far field, so not very good at penetrating water in the same way that the magnetic near field measured by SAR testing is.
