Iodine 131 half life is a bit over eight days.

Dilution in time is a rate, a time rate.  With a slow time rate of
addition to the environment, especially I-131 is a non issue due to its
rapid decay.

Space is usually a volume.  Mass per volume is dilution in space and a
concentration.

If we consider a one dimensional space then "meters from the shoreline"
seems to work pretty good too as some kind of mixing function, but I'm
not sure what is the one dimensional analogue of mass.

Don't you think we should do a little better job of providing for reasonable dilution?  I know these are difficult times for TEPCO and I know the ocean is very big, but I hope someone is asking these questions in Japan.
