And even more of an issue when the units are for different things. Rem is for the biological dose, i.e. the effect of the radiation, rads are for the basic radiation dose to any medium. They are outmoded, being replaced in most countries by the SI Units sievert and gray.
I don't think nuclear dampers would be much use, as they only effect radioactive decay of materials: the radiation belts of Jupiter are largely made of of radiation particles, electrons and ions, IIRC.

It's also going to be amazingly cold, Europa's surface temperature at the equator for example never rises above minus 260 degrees Fahrenheit (minus 160 degrees Celsius), so all equipment and structures would have to be built to take it. There's also geological stability to consider and while Io may be a cool to watch at a safe distance, you could never put a permanent colony there.
