According to a large team of technical and health specialists, astronauts aboard the Orion spacecraft will be well protected from radiation when the Artemis II mission travels to the moon and back next year.

Space is full of radiation. Charged particles swarming interplanetary space mostly originate from the Sun with the occasional interloper from the rest of the Universe. On Earth, we are protected by it thanks to the planet’s magnetic field and the atmosphere – astronauts are not.
