Be careful that light-bulb in your room puts out 10-100x the radiation of your cell phone.

THz is non-ionizing, for one.
OP suggests that THz radiation is ionizing - it is not.
OP maintains that a lightbulb emits "10-100x" more radiation than a cellphone - at what frequencies? Is he talking about power or intensity?
On power vs intensity since our distance from the sun is relatively fixed intensity is a better unit while distance from a radio tower is variable so power is a better unit. I also figured that a smart crowd like this would appreciate that you would be exposed to much less radiation standing next to the tower than standing in the sun and that it falls off at inverse square from the tower.
So I always forget technically ionizing UV is not in the terahertz range, however ionizing like damage to human biology does start in that range and is not a thermal effect.
The lightbulb statement was power and again was just a quick way of trying put it in perspective.
You can say what you like but one thing is clear: there is absolutely no consensus among scientists that EM radiation from mobile phones has absolutely no negative influence on human health.
Radio is much lower frequency than light, once you get below the UV spectrum the only known effect that light and radio have is thermal, that is heating flesh, ie heat lamps, microwave ovens.
Yet everyone walks around outside under orders of magnitude higher intensity radiation that has full scientific consensus to cause cancer without giving it much thought.
I for one am not worried about my cellphone that has the power output of a led penlight.
No, inverse square.
> has to speak to a tower miles away
But the tower has a very sensitive antenna, so your phone doesn't need to put much power into transmitting. The effect of the phone on your brain and body is small compared to ordinary thermal noise at your body's temperature.
> putting it against your brain for hours on end
If you're going to be talking that much and are worried about this (which I don't think you need to be, but everyone has to make their own judgments), you can use a bluetooth headset. Bluetooth transmit power is an order of magnitude smaller, at least, than cell phone transmit power.

You probably have incident on your body more energy sitting under a light bulb than from a cell phone, not to mention the nuclear fireball in the fucking sky.
Interestingly though, in some environments you can actually get better than free space loss. I remember an off-hand comment from a professor in university that in concrete tunnels you can get R^1.6-1.8 because the tunnel acts as a waveguide
