I might look it over in more detail later this week...
The short answer is EM radiation CANT do anything to mitigate high energy charged particles in field free space.
A free unbound electron cannot absorb a photon, but electrons orbiting in a magnetic field can.

What is happening here is that the VLF is interacting with the particles trapped in the earths magnetic field-- it is not eliminating the radiation belt, it is just changing it's location (at least that is the speculation).
Space/Science » in reply to How can we know how VLF waves would interact with cosmic radiation in the absence of a magnetic field?
I only scanned the paper
