CBC's MarketPlace had Wendy Mesley investigating cell phone radiation and the standards and warnings that surround it, and there does seem to be some question as to the true dosages we are getting, and some surprising anecdotal evidence of numerous cancers in a small area, etc.
I was at a watchmaking class, we were servicing the venerable Rolex 1570, kindly provided by Lititz Technicum in PA, a couple years ago. I had my movt fully re-staffed and CTR'd and sitting in its cradle on the Witschi (Watch timing computer) when one of the students said he had noticed something and wanted to show us.
He stood beside my bench, with his cell phone in hand, a web page showing. He was going to click on a link, and he was about 6- 8 inches from the movt in the microphone cradle. What happened next was a bit shocking. He clicked.
The Witschi completely lost it, the nice flat line I had been observing as I regulated the movt disappeared, to be replaced by noise and artifacts on the screen. We had to re-boot it, and the watch itself took two attempts at de-magnetisation before it would behave itself again.
It immediately made us all wonder about the strength and effects this field had on our tissues. It was strong enough to magnetize a hairspring and various steel parts at a distance, and the Witschi didn't like it either.
Now granted, this was an uncased movt, and steel in the form of tiny parts and ribbon springs are fragile, but I can tell you I no longer carry my cell phone in my pocket, especially after the Market Place investigation, which showed 4 independent tumours in a woman's breast, in exactly the place she kept her cell phone- tucked in her bra.
Just something to consider.
