How much radiation do the moons of Jupiter receive?

The moons of Jupiter get different amounts of radiation due their variance in distance from Jupiter. For example, Io is closer in and gets about 3600 rem per day, Europa around 540, while Ganymede around 8. read more

Like the Earth, Jupiter has a magnetosphere that is a region where radiation from the sun, and volcanic emissions from Jupiter's moons and ring interact with the planet's magnetic field. This field is the strongest and largest in the solar system, about 18,000 times stronger than the Earth's. read more

Radiation in the form of high-energy electrons and ions continuously bombard the top layers of Europa’s icy crust. This deadly dose is due to the fact that Europa—along with the three other Galilean moons (Io, Ganymede and Callisto)—orbits within Jupiter’s radiation belts. read more
