The radiation emitted from your phone is mainly caused by how much energy the phone needs to use to pick up a signal. So, by using your phone is Airplane Mode you are effectively mitigating the risks you may experience from mobile phone usage.Airplane mode turns off all the radios in your phone into an iPod with no connectivity at all.

-Mark Lerner, Tawkon

As such, whatever the risks of radio might be, putting it in airplane mode disables the radio so there is zero risk.

Mobile phones work omnidirectionally.

If you were to cover yourself from incoming waves, your phone wouldn't work anymore. If these products really worked, you'd have a drop in signal so high that the phone would drop connectivity (Faraday cage)

No.

All mobile devices follow the same WHO rules on emissions and all are safe (as far as we knoew from all current scientific understanding).

The whole point of a cell phone is to radiate. That's how it sends your voice to the cell phone tower. To get a cell phone to stop radiating, you'd have to wrap it entirely in aluminium foil. At which point you could just stick a brick in your pocket instead, because the cell phone would be useless.

It actually takes a few layers of aluminium foil to attenuate the signal enough to be completely useless.

Any conversation where you hold something to your head in a generally unnatural and uncomfortable position, and that lasts an hour (ie, probably tiring and stressful) could cause a headache.

-Torlyn Holstein, Forensic pathologist

It is more likely to be caused by the concentration you devote to the discussion. Secondly, the volume may be a bit loud.
