It means there are isotopes, including tritium, whose half-lives are long enough that they pose a risk to the health of anyone who happens to inhale or ingest them. The OP's dismissal of such risks is a bit facile.

But tritium pretty much can't be made in light water reactors, so there isn't going to be any in the released steam.

True, but the reactors aren't full of light water anymore, they are pumping sea water into them.
