Exposure to a nuclear detonation at 4000 yds typically kills about 1 in a
million cells. When that happens, you die. I would suggest that is a
Losing one atom in every thousand cells is not the same as losing the cell
itself. Cells are a constant work in progress. Bits fall off,
transcription errors occur in the process of making proteins, radiation or
noxious chemicals damage subcellular components, and so on. The machinery
of the cell is constantly at work repairing all this damage. It is like a
building project where the builders only just manage to keep up with the
wreckers. Eventually, errors accumulate or the blueprints are corrupted
and the cell dies. Taking the organism as a whole, the effect of all this
activity is like the ship of Theseus: over time, even though it looks like
the same organism, almost all the matter in it has been replaced.
That's correct, of course. I'm finishing up a book on nuclear fallout,
and most of my selves were obviously immersed in radiation issues rather
than simple mathematics. Sorry.
