According to the journal: Radiation Protection Dosimetry, Vol 20, No 3, 
p133 (1987) -

The journey would be around 500 mSv (assuming a three year mission)

A suggested annual dose limit of 500 mSv

A suggested career limit of 4 Sv.

There may be more interesting stuff in the journal, I'll look it up if 
anyone is interested.  (I summarised that info for 'educational' purposes 
a year or two ago.)
