Instead, they saw levels of high energy particles surge within the core itself and gradually spread from there. This seems to confirm the idea that the Earth's magnetic field is acting to accelerate particles, some of them to relativistic speeds. It took a few decades, but it looks like we've finally got a better handle on the Van Allen belts.
