Radiation Dose to Nuclear Submariners

[VERNIG.PETER@FORUM.VA.GOV]

Group,
This is something outside my experience.  I had a patient/veteran
ask about radiation dose from medical proceedures.  He was concerned
because he said he had been told that he had received his total life-
time dose and should never be on a sub again.
 
Does anyone out there in Radsafe land know what kind of dose ranges are
possible serving on a nuclear sub?
 
To reply privately please initiate a new message to me at 
vernig.peter@forum.va.gov.  Using a reply or answer function will
LIKELY broadcast the response to all of Radsafe.
 
Regards,
