Ashley, I should have been more explicit in distinguishing between potential adverse effects from analog compared with digital, particularly CDMA. My intent was to argue that if there are adverse effects from exposure to electromagnetic radiation (a big if), then they are likely to be far more pronounced with analog than with CDMA. That's because, as I understand it, a CDMA transmission is essentially a series of minute pulses, whereas analog is continuous. Even if one assumed the RF power output was the same in both analog and CDMA, the total AMOUNT of power to which the person speaking into a handset would be exposed would be far less with CDMA.

The main issue, of course, is whether one can find a causal relationship between exposure to electromagnetic radiation and headaches, tumors, or whatever. I argue simply that if the research involved some cases using analog and some using CDMA, and no control between the two systems, it would be fundamentally flawed. I have seen no research reports that were based solely on CDMA, or even digital transmissions. If there are any, so much the better.
