Ethicists Tell NASA How To Weigh Hazards Of Space Travel

Zeitlin and his colleagues estimate that astronauts would be exposed to
about 0.66 Sievert (Sv) -- the unit scientists use for measuring radiation --
of galactic cosmic ray radiation during the round-trip to Mars, not
including their time spent on the surface of the Red
Planet.
About 1 Sv of radiation exposure is usually associated with about a 5
percent bump in fatal-cancer risk later in life.

I agree with the panel. Explain to the astronauts the risk in an honest
way, and let them decide for themselves. I don't see any big difference
between this and let's say mountain climbing or any other dangerous
sport.
