 The designers of Galileo had a strong motive to use RTG designs that don't
leak large amounts of hard radiation: Galileo's electronic systems. It
wouldn't make sense to use a power source that toasted the system it was
powering, and electronics can be pretty unforgiving of doses of short 
wavelength EMR and charged particles. (I had a co-op Electrical Engineering
student comment to me about the poor performance of circuit boards exposed
to 5000 Rads, although he -wouldn't- what working environment his test boards
were intended to be used in.)
