A basic irrational fear of excess radiation has kept me from buying all sorts of cool devices, including mobile phones and wireless networking devices for my home. The fact that no adverse effects have been found in years of study doesn't help my fear much. It is an irrational fear, after all.
My friend Tom Duff says that, in that band that wireless devices operate, the wavelength is so large that the signal doesn't carry enough energy to cause chemical state changes in cells. Thus, it can't break chemical bonds or otherwise fiddle with any cellular state that matters. Thus, no danger to whatever body parts I might be paranoid about. (Phones spend their time in pants pockets, shirt pockets, and next to the head. All the vital organs! Yay!)
His logic makes sense to me, though I'm mostly taking his word for it. Just as I stopped glaring suspiciously at my microwave several years ago, I'm beginning to warm up to the idea of a mobile phone. Travelling last weekend reminded me how useful they are, and with a baby on the way, it would help for me to be more accessible in an emergency.
So today I was actually shopping around the web for mobile phones, checking out the various carriers, trying to make sense of the endless sea of calling plans. I'm this close to buying one, and I pause for a moment to read Slashdot, as I often do. Lo and behold, an article on wearable technology offhandedly mentions Levi's new anti-radiation pants for mobile phone users.
Rrrgh. Irrational fear returns. Dammit. I might as well just sprinkle goat's blood around all the electrical outlets in my apartment to keep the electricity demons out.
They're there, you know. In the walls. Watching.
