    stop it IMMEDIATELY. i have just spoke for 3 hours on a cellphone and i feel like i kept my head in the microwave oven. after only few mins i already feel my brain heating up and then it hurts, so i had to change sides all the time. just get a extension cable. don't ever put a cell phone on your head again.

    And unfortinately people are trying to earn a lot of money by making people think that non-ionizing radiation is really bad for your health.
    Recent examples (in the netherlands) are personalFloww or Bureau Straling Meten and many more =/

    Look up Gwen towers cell towers have more than enough power to supply just cell reception but there's a darker reason behind this.

    Here's another consideration. have average call times and frequency of calls increased. while we are on our phones and cellular devices more than ever, when we aren't taking a call we're facebooking, tweeting, surfing the web. these activities don't place the phone close to the head. Is this variable relevent to the research?
