...my Uncle Ernie used to say that the Moon astronauts were never the same when they came back.

The article says the effects would be in "deep space" -- but we haven't gone there yet. AFAIK, there's been no study showing harmful effects to any of the astronauts on lunar missions, Skylab missions, or EOS missions.

I meant ISS missions.

Once you get outside the Van Allen belt, I don't know what would distinguish the radiation levels of deep space. That runs from about several hundred to tens of thousands of km. Even commercial aircraft that fly at 10,000 m altitude or so have to meet additional radiation specs because of loss of protection from the Van Allen belt. Satellites that are in low earth orbit (400 to 600 km) have slightly more additional radiation specs beyond what a commercial jet would have while satellites in higher orbits (geo-sync at 42,000 km, for example) have significant radiation hardness specs.

So typical space shuttle flights would expose astronauts to significantly more radiation than on earth or even in a transatlantic flight. Flights to the moon or mars would expose them to even more.
