This is not my area of expertise area, but I think watt is a unit of power and eV is a unit of energy - the eV needs to be converted to a rate (energy/time) to be a unit of power (response 1). Maybe the denominator was left off? ... although the conversion looks a bit odd, too... maybe I'm missing something else.
Back to lurking and pulling out the books.

Chris,
If I asked too many questions, I apologize. Let me ask fewer, and
clearer:
You said: " I believe that the carcinogenic effects of RF are due to
increasing the energy of electrons produced by ionising radiation,
either from the (major) photoelectron tracks induced by gamma background
or the beta tracks from internal emitters. What is the energy (in eV )
added to an electron."
1. What is the energy, in eV , added by the RF from the cell phone to
the electrons produced in the other ways? I would accept a range of
numbers
If we take the limit of 1.6 watts/kg this is 1.8 E+21eV per kg tissue. But much higher in near field.
The serious beta electrons are about 10keV to 100keV.
Per electron I havent done but interesting thought. Could be done.
2. What experiments were done to demonstrate that this energy exchange
takes place?
Im trying to get to do these. But you can see from cloud chamber tracks that at the end if its path the electron spirals
3. The energy of a free electron is its kinetic energy, which includes
its speed and direction (I think we can stay Classical for this
discussion, but if you wish to go relativistic, feel free). Why would
RF energy from a cell phone only add to the energy of an electron, and
not potentially decrease its velocity, and hence energy? In particular,
if you had two electrons traveling in opposite directions when the cell
phone energy entered the system, would not the velocity of one increase
while the velocity of the other decrease?
Its not a decrease but a wiggle, so the effective path length increases
The RBE increases, more ions per cm.
Anyway, we shall see.
Chris

Well thats a lot of questions.
The energy of an RF field is proportional to the square of field
strength. All the enrgy is transferred to electrons. Just like in a
cathode ray tube.
The range of the elctrons is equal to their CSDA range and depends on
the decay energy inthe case of internal nuclides and equal to the gamma
photon energy less the binding energy (which is second order) in the
case of photons. For Sr90 the range is about 400 cells. For tritium a
fraction of the cell diameter.
In the case of natural background the photoelectron energy fllows the
gamma energy which goes as E^-3 roughly and as Z^5 in terms of the
absorber, which is why U238 is so dangerous. Z=92. The B filed causes
the electrons to jump about aand spin in spirals, bunny hops. And so
increase their LET. For the external background it is the low energy
electrons that cause the greatest harm.
The RF energy has been measured from mobiles. It is very large, watts
per cc, but the belief is that these watts are not dangerous as the
energy cannot be absorbed by covalent bonds. This is true, it is a
question of quantum resonance, and the energies are beyond even the
rotational levels of simple diatomic molecules.After all the watts per
cc from ionising is Grays per second per cc. (1 Gray = 1 joule per kg).
The mechanism is well known. It is the same mechanism as a cathode ray
tube focusing ring. Put an electrron in a E or B field and it moves. I
would have thought that radsafers knew that. If you look at cloud
chamber trac ks you see that at the end of the track the electron curls
up in a spiral. That is the effects of the magnetic filed H(0).
If I havent answered everything let me know and ill try. But the real
answer is toi do experiments with a end point and run ioniosing and non
ionising together. That will give the answer.
Chris

Chris,
What is the energy range of the electrons produced from the
photoelectron tracks induced by gamma background or beta tracks from
internal emitters? (I recognize that the energy of the electrons
ultimately drop to some fairly low but non-zero level, at which time
they get attach to some likely atom or molecule with a more positive
attitude). What is the range of energy that the RF adds to the
electron? Does the RF in question ONLY add energy to electrons, or does
it also slow down electrons that are traveling in the opposite
direction? (If it only adds, I would be fascinated to know what the
mechanism involved is) If the RF adds energy to some electrons, and
subtracts energy from other electrons, or if the amount of energy added
is small compared to the peak energy of the electrons produced by gamma
background or internal radioactive decay, is it reasonable to spend time
and effort on this, as opposed to something that will reduce population
dose more?
And is there even the slightest chance that the risk from RF from cell
phones is within orders of magnitudes of the two major health effects of
cell phones?

Dear Radsafers ,
I have been looking at this in between everything else since 1998 when I
was funded by Children With Leukemia to do some reseacrh on the issue. I
believe that the carcinogenic effects of RF are due to increasing the
energy of electrons produced by ionising radiation, either from the
(major) photoelectron tracks induced by gamma background or the beta
tracks from internal emitters. The electron energy is modulated by the B
field of the
RF Electromagnetic radiation.. Thus the electrons borrow energy from
the EM field which they then deposit in tissue as ionisation . This gets
round the fact that the quantum energy of th EM photons are not absorbed
by any energy levels available in molecules. We are currently examining
this issue in the laboratory. It is odd that no one has thought of this.
I suppose because you all imagine these background levels of exposure to
be harmless.
Chris

"WHO: Cell phone use can increase possible cancer risk
http :// www . cnn .com/2011/HEALTH/05/31/who.cell.phones/index. html
according to the World Health Organization. The agency now lists mobile
phone use in the same "carcinogenic hazard" category as lead, engine
exhaust and chloroform.
Before its announcement Tuesday, WHO had assured consumers that no
adverse health effects had been established.
