Exposure, even of short duration, to the most intense parts of these radiation belts being fatal, the protection of astronauts by adequate shielding and the selection of trajectories minimizing exposure is necessary.
Only Apollo astronauts who traveled to lunar orbit passed through the Van Allen belt.
They spent a few minutes in the inner belt consisting of energetic protons and one and a half hour in the outer belt of low energy electrons.
The inclination of the Moon's orbit was such that the tori were not crossed at their center and the trajectory avoided the most energetic sections.
Finally, doses received during lunar missions - including belt crossing and exposure to cosmic radiation - were relatively low.
The Apollo 14 astronauts were the most exposed with an absorbed dose at the skin of 1.14 rad, or 11.4 milligrays.
Considering a skin weighting factor of 0.01 and a radiation weighting factor of 20 (the most penalizing case), the Apollo 14 astronauts received a dose of 2.24 millisieverts; by comparison, the annual limit for nuclear workers in France is 20 millisieverts.

Did red this on wiki, didn't know about thoses infos, nice to know and it was because of flat earth comment about van allen belt
