[Rouse, Raymond Lawrence]

Mike,

Please include calculations on radsafe some of us would like to the
methodology.

Raymond

Chris

Shall we try some calculations? Shall we do them on RadSafe or offline?

Dear Mike,
Whats your point?
I said thats the effect of the magnetic field H(0). Thats the earths
magnetic field. Which I hope is constant.
I think we can conclude that much more intense alternating fields will
therefore have the effects I am talking about. Yes?
Sincerely
Chris 

The magnetic field of an electromagnetic wave does not cause an electron
to move in a spiral. A constant magnetic field does so, but not the
alternating magnetic field of an electromagnetic wave.

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
