What is it? Where did it come from? And what does it require to safely circumvent it?

Thanks to its liquid metallic core, the Earth has magnetic field, the magnetosphere, around it. The magnetosphere shields us from the solar wind, which is a stream of highly energetic particles coming from the Sun.
When the solar wind impacts the magnetosphere, some is deflected, some glides along the field to the pole, resulting in auroras and some is trapped in layers. These last are the Van Allen’s Belts (2, in case of Earth)
Their thickness and radiation intensity vary, but you cannot circumvent it. This, and astronauts’ exposition to the solar wind during interplanetary missions, is why the development of radiation protections is a crucial part in space exploration
