Cell Phonophobia

I was browsing around, looking to see if there might be some way to use our 300 free long distance minutes (Verizon) from down here in the reception-free zone of our little canyon. Do internal or external antennas work?

Ran across this FAQ re Cellular Phone Antennas (Mobile Phone Base Stations) and Human Health and (especially in light of a conversation yesterday with a physician friend who leans toward the 'yes they may be dangerous' point of view) thought this might we worth posting. Your thoughts?

There's been a lot of discussion on this very topic up here, north of the 49th and, as my niece reliably informs me, over in the UK. I have to admit, I gave up use of my mobile, but not because of the potential dangers, of which I'm sure there are some, but, more because I was fed up being rang at all hours of the day and night by people, getting hold of my number, who I didn't really want to speak to.

Meanwhile, you should also do a little research on the radiation your computer gives off and, the potential damage that can be done to your eyes.

We live a different life.

Only CRT monitors emit radiation, LCD's do not...they do not tire or strain your eyes either.

CRT's cause eye strain by the way the electron beam is scanned line-by-line down the screen (the back of the tube) at a set rate that produces a flicker. CRT brightness is another eye strainer. We turn up the brightness to make reading text easier but the more light that is emitted the less crisp the image(blooming). You're sort of damned if you do and damned if you don't with CRTs.

An LCD has millions of picture elements, each one independent from it's neighbor and does not rely upon a scanning electron beam. The image is always perfectly "focused" over the entire screen and has no flicker. The only issue with LCD's is a edge blur from a side viewing angle...this has been reduced in the current generation of LCD screens to an acceptable level. I would never go back to CRTs.

However, if your CRT monitor allows you to adjust the screen refresh rate, set it higher to eliminate screen flickering which causes eyestrain. 70Hz to 85Hz is optimal. Avoid adjusting the refreshment rate too high as it will degrade image sharpness.

Don't be fooled! LCD's DO emit radiation!!!
