Re: Iodine 131

This a big picture view from my memory, since I can't find any references
right now.   If you need more precision, it may take a couple of days.
Iodine is a fission product.  The immediate relative abundance of fission
products has been plotted graphically by the atomic weights of the products.
Three or four iodine isotopes, including Iodine 131, are near the top of one
of the peaks on the graph.   This is a result of the characteristics of
fission, it tends to create two relatively large fission products.  The
effect of neutron flux (burnup) on the initial fission products is also a
factor.  Some of the iodines may also be in the decay or burnup chains of
other fission products.
