I mean, we've got a tiny space station up there with metal walls that basically make it a tin can in comparison, and people seem fine for months at a time?

Also, the US has been planning a manned mission to Mars for some years, and nobody at NASA seems panicked over everybody they send, dying from it.

It's not dDR it's number of systems. See Spaceships 5. Especially the part where cosmic rays divide conventioanl PF by 100.

The ISS is inside Earth's magnetosphere which deflects most of the charged particles that make up cosmic rays.

At NASA the people in charge of human factors are intensely woried about long term radiation. The people working on other aspects of a Mars mission are just hoping the human factors group solves their problem.

Outside of NASA peole like Robert Zubrin are confident that they can find astronauts (or maybe "astronauts") who will make heroic sacrifices like dying of cancer after they get back to Earth.
