eli5: Carrying phones on us all the time and no adverse effects?

512 views

I mean I ‘know’ that carrying a thing in my pocket that has a sizable battery and sends mass amounts of rays through your body continuously throughout the day would ‘logically’ point to ‘more than likely’ but then in practice – there is no side effects. So does our body have a natural defense for all of the above?

Radio waves at the frequencies used by cellphones (and radios and formerly TV) don’t interact with biological matter. So it’s not really a question of defense, they mostly just go through you.

Radiation is a scary word. Ordinary light from a desk lamp is radiation. But colloquially when people say radiation they mean ionizing radiation. That’s particles or waves carrying enough energy to start knocking electrons around in your cells or cause transcription errors while your DNA is making copies. The frequencies used by consumer electronics don’t operate at those energies and that is why they are deemed safe.

What if I told you that you were to be placed in a room where your body would be subjected to collisions with billions of tiny particles moving on average 1000 mph. How much do you think that would hurt you?

Now consider that is just sitting in a normal room full of air at a normal temperature. There is a scary way to phrase even mundane conditions when you don’t really understand what is happening. In the case of “massive amounts of waves” traveling through the body it matters a lot what kind of waves you are talking about. X-rays? Not good! Radio waves? Who cares? They are different kinds of waves and interact differently with the body.
