Jon, while it's true that the energy in a CDMA cyberphone photon is too low to ionize DNA and cause cancer by itself, it is not too low to add to the energy of other photons which are being absorbed which ARE high enough in energy to almost ionize the absorption point if only they had just that bit more energy, which they get from the CDMA photon which kindly offers its services at just the right time.

There are a LOT of photons, so while the occurrence of such events is low, there are so many of them that they are happening frequently.

But not so frequently that there is brain cancer caused at sufficient rates that small epidemiological studies can find it.

The CDMA photons are very low energy and the power output is very low in CDMA as you say, compared with olde-style blasting analogue systems, so per hour of talking is now much safer than previously [which was already so safe it wasn't worth worrying about compared with the advantage of talking].

Antennas are now right beside the brain instead of sticking up above the head, so proportions of absorbed photons are higher now. The measure to use is specific absorption ratio. Test heads and phones are used to measure the absorption to see how dangerous a phone is [or how much relative risk there is because the danger is not able to be measured yet, other than to say it's so low that it's not really a concern compared with other hazards in life].

That equation MQ + X = 2C defines the rate of cancer formation. [I should add that it's a prototype equation not fully tested yet - see upstream links for definitions of variables. It's in my shed waiting for more experiments].

PS: I don't think average output of analogue phones was 300 times as much as for CDMA phones. I thought it was about 2 watts compared with 100 milliwatts = 20 times as much.
