US Law allows radiation dose up to 3 rem per calendar quarter for any worker
(29 CFR 1910.96 (b)) provided the lifetime dose is not exceeded.
LLNL is presumably governed by AEC and/or DOE and State of California 
radiation regulations which may be different, probably more stringent.
This may determine rotation times, rather than 0-g, and would negate the
benefit of artifical G.  If 90 days is the limit, no point in spinning
the station.
  The Soviets operate at lower altitudes than Freedom is planning, so their 
radiation exposure is less.   Plus they probably allow a higher accumulated 
dose  than US.   
  Going off-line, this will be my last post until ca 27 Nov, 
flamethrowers please note.   I shall return  O<~
