When you get on an airplane, they tell you to turn off your cell phone as it may interfere with the communication of the aircraft. Is holding a radiating device next to our head interferring with the communication in our brain?

I use a wired headset and keep the phone away from me. Please be careful in purchasing radiation blockers, I have problems with some of their claims. Here is what cell radiation looked like after 1 hour on the phone, do you see any differences between sides of the head?

For people wearing a bluetooth device, are you getting radiated twice and is the phone in your pocket radiating you elsewhere?
