Re[]: neutron flux in space - Spacecraft Design

     As long as this thread is still tight:
     
     Assuming LOX (liquid Oxygen) is aboard the shuttle, what is the 
     potential Deep Dose Equivalent from Nitrogen-16?

I remember discussing the problem of designing a spacecraft relative to 
the radiation environment in physics class.  Apparently there are two 
problems.  Shielding against low energy radiations (the neutrons) and 
having too much shielding.  Too much shielding will create a buildup of 
dose from the high energy particles.  The spacecraft were supposedly 
designed to have nearly identical shielding in 4 pi geometry(?).

Interesting.
