Cell phones aren't "emitting" signals while in your pocket. They're largely receiving signals and sleeping. We have many devices that emit 10Watts of EM radiation at us every day: we call them light bulbs or LEDs. Cell phones are only allowed to emit 3W IIRC. It wouldn't surprise me if the screen has more EM than the radio.

False. Cell phones are emitting signals throughout the day, in bursts. LEDs and light bulbs do not emit modulated microwaves. If the screen emitted substantial RF radiation, the FCC (and related agencies in other countries) would have something to say about it.

  Light is further up the energy-line of electromagnetic radiation. Least-dangerous -- Radio / Infrared / Visible Light / Ultraviolet / XRays / Gamma Rays -- Most energy/dangerous All light-bulbs, screens, LEDs (etc. etc.) emit visible light. There's a couple of bands in there that might be more dangerous than others (ex: Microwaves specifically resonate with water), but for the most part, Gamma Rays are the most dangerous, and Radiowaves have the least effect on our body.

    False. Again.

    @dragontamer: "Radiowaves have the least effect on our body" - but what happens when you modulate them at a secondary, low frequency, that disturbs voltage-gated cell-membrane ion-channels? Just hoping to pique your curiosity into the field of biology and away from hyper-reductionistic physics models.

      > that disturbs voltage-gated cell-membrane ion-channels? You're begging the question. You could have more easily stated your opinion as "low frequency radio waves disturb cells". Which is fundamentally false. There are lots of radio-waves being used around the world: RADAR systems, Radio-headquarter units... as well as people who live nearby radio-towers (TV, AM Radio, FM Radio), and cell phones. Do you think WW2 units fielded with SCR-300 (World War 2 backpack radio) had increased amounts of cell membrane damage associated with them? https://upload.wikimedia.org/wikipedia/commons/c/ca/Scr300.png https://upload.wikimedia.org/wikipedia/commons/c/ca/Scr300.p...
