Maybe my question should have been not to ask what I131 decays
to, but
rather what decays to I131.

Cadmium 131 and 132, and Tellurium. (presumably from the cladding of
fuel rods rather than anything directly in the uranium decay chain)

I-131 decays to Xenon-131 (stable). According to Winky, I-131 is a
major
decay product of uranium fission.

Do you have a reference, I could not find iodine in any of the Uranium
decay chains I looked at - perhaps I am missing one?

Only the first para of:

Its not a product of decay so you are looking for the wrong thing.
