Space X announces to send tourists around the moon!! (But)

How exactly does Space X plan to defeat the mighty, impenetrable Van Allen Radiation belts? The Van Allen Belts are bands of lethal radiation that would/will kill anything that passed/passes through them!

Guess what sits BEYOND the Van Allen Radiation Belts?  THE MOON.

Here’s NASA admitting that they haven’t sent humans through this part of space yet (Where the belts reside). How’s that? You flew through this region of space when you went to the moon, remember.?  Why not just use the shielding technology from the old moon missions, when you landed on it?
