From what I've read, it would be pretty intense, and no way to turn it off. Add to that a travel time of several years, and the whole project seems unlikely

I think colonizing Callisto would be possible. It's outside the main radiation belts so it's significantly safer. The same can not be said about the inner 3 moons though.

You’d die. Painfully. On the upside you probably won’t take that long to die.

From what I understand:

-The intensity of radiation on Io and the surrounding space is practically unbearable for anyone, even with existing protections that can be added to a spacesuit without making it unusable. Although Io's volcanoes could be an attractive energy source once the other moons are colonized.

-Europe is an improvement over Io, though not vastly better. I think it can be endured for only a few minutes on the surface before the dose becomes lethal. Any attempt at colonization would have no choice but to be carried out by burying the habitats under the ice, preferably in caves or canyons.

-Ganymede's radiation situation is orders of magnitude better than that of Io and substantially better than that of Europa, plus the moon also has its own magnetosphere (albeit shadowed by Jupiter's magnetic field) such that human settlement on the surface would be feasible. It would also be a feasible candidate for terraforming.

-Callisto is the most promising of the Galiean moons for human colonization, due to its distance from Jupiter's radiation belts. It was also the target selected by the HOPE (Revolutionary Concepts for Human Exploration of the Outer Planets) study. Building settlements on its surface should be quite feasible, and it was even considered that such settlements could be used as a fuel producer for further exploration of the outer solar system.

Well if it's harmful radiation, and we have to assume it is, it will tear through our DNA as it radiates doing irreparable damage to us. Just look at the demon core incident. There's, what I believe, a really good video essay on the demon core by Kyle Hill on YouTube if your interested, but that's off topic.
