This is more of an information post than a question, but maybe it will raise some interesting discussions around what could be the cause of this shield.

I think the Plasmasphere scenario makes the most sense but is that enough to channel/stop high energy particles on its own? Could the way the belts themselves are structured be a part of how this barrier is formed?

This is more of an information post than a question,
and is therefore moved from Q&A to Astronomy

Well I had 2 questions at the end...don't they count..;)
Guess it wasn't as interesting a topic as I thought it was anyway.

Another scenario is that the giant cloud of cold, electrically charged gas called the plasmasphere, which begins about 600 miles above Earth and stretches thousands of miles into the outer Van Allen belt, is scattering the electrons at the boundary with low frequency, electromagnetic waves that create a plasmapheric “hiss,” said Baker. The hiss sounds like white noise when played over a speaker, he said.

A hiss? Ions moving in a magnetic field create microwaves...The microwave background is a hiss - what is the frequency range of this local hiss?
