Jupiter's radiation is so intense that Europa Clipper has a _super weird_ mission profile (a bunch of fly-bys instead of an orbit) so that the spacecraft doesn't spend too much time cooking in all that.

Yes.

> Near the planet, the magnetic field traps swarms of charged particles and accelerates them to very high energies, creating intense radiation that bombards the innermost moons and can damage spacecraft.

So basically like our van Allen belts but supercharged.

The quick answer: Yes and from a human visitor perspective, lethally high amounts. It's the single most intense emitter of radiation in the solar system except for the sun itself. If we wanted to colonize any planet with plentiful moons, Saturn would be a much better candidate at least in this regard.

Also, though another reply here mentioned Jupiter not emitting its own radiation, this isn't quite correct. It does, almost like a small pulsar.
