Why not Skylab Redux?

The CEV would have the same problem.

Yes, but.

Yes, it would have to pass the Van Allen Belts, but as with Apollo
speed, angle, and timing would minimize exposure.


This is actually the reason I proposed a cycler in the first place.
Once at L1, it could be shielded with lunar water (assuming it exists).
Then put into a cycler orbit, enabling comfortable, safe transit.

How much water would have to be used? Say, a 10 person crew, 2 week
transit time. Assume that no crew member will do more than 1
out-and-back trip (new crew every occupied cycle), so you can use up
most of the lifetime exposure limit.
