Unless of course the fusion fuel you specified doesn't produce neutrons. Off
hand I can't think of a Gama source on the ship, unles we use antimater. In
that case we have a very hard radiation problem in general.
We might have more problems with cosmic radiation, especially on fast ships.
But given the tolerance of the food vs the human crew I don't, think, it
will be a problem. Certainly less than with a farm where the food has to be
kept healthy to grow.
