The distance that cosmic rays travel to meet the Earth is four orders of magnitude greater than the radius of our Galaxy

The distance that cosmic rays travel to meet the Earth is four orders of magnitude greater than the radius of our Galaxy. Does this mean that cosmic rays come from regions outside the galaxy?

Charged particles move along spiral paths along the lines of force of magnetic fields, which can have a complex configuration. As a result, charged particles of cosmic rays, while remaining inside the Galaxy, travel a path that significantly exceeds its radius.
