I don't actually see much reason you shouldn't go to TL10. It would mitigate but not remove the radiation issue and gnerally make the amount of human activity you have all pover the soalr system more credible. If you don't want laser pistols nerf power cells.

...The spaceship I designed (which might be upgraded to TL10 anyway) has a minimum of 50 dDR, so radiation should not be too much of a hazard?

I mean, we've got a tiny space station up there with metal walls that basically make it a tin can in comparison, and people seem fine for months at a time?

Also, the US has been planning a manned mission to Mars for some years, and nobody at NASA seems panicked over everybody they send, dying from it.
