Didn't Dyson's son write in the book that part of the reason for the treaty's signing was internal politics to kill a competitor to NASA? 1. Those 0.1-1 dead is from a period of much worse cancer treatments than will be available a few decades after an Orion launch. 2. It is bad risk counting. The cost per life is a factor whenever e.g. roads are built and speed limits are set. ("We will get ~ X less deaths/decade if we build the motorway differently, but it would cost over our limit for $/life".) Also, just transporting materials/people when designing/building an Orion ought to be a lot more than one dead.
