Here is the NASA Ames study on human babitation in space.

It shows that 5 REM per year is acceptable. That is the limit for
radiation workers. The study also shows that in deep space 280 grams
per square cm of habitat surface is needed for sheilding in deep space
to keep radiation levels down to 5 REM per year.
Most crops are grown in 100 days or less. Most animals grow to
maturity and slaughter in less than 3 years. Some less than 1 year.
Reproduction and gestation of these animals can occur in sheltered
environments - storm cellars - that mainain genetic vitality of the
reproductive members while the non-reproductive members fatten in 5
REM per year climates. .
This is deep space.
Near Earth space is far less energetic. Especially under the van
Allen radiation sheild. That's why I know I can cut total habitat
mass considerably by choosing the right orbit.

Whatever you do, don't go anywhere near the expanding an deepening
SAA, because it's a real killer.
BTW, Raytheron TRW Space Data report has the GSO environment at a warm
and fuzzy 2e3 SV/year (that's only 200,000 rad/yr), and thank God or
your lucky stars, that's while fully shielded by merely 5/16"
aluminum, and at that only having to survive one halo CME.
Mook got rad-hard DNA ?
