      4 billion tons at 3 ppb… It’s so much water, don’t try to drink it either.

      Yep. Best estimate I have seen is 4.5 billion tons of uranium. Course, most of the natural radioactivity of our ocean is from potassium, actually. But either way, natural levels of radioactivity will not change.
