Unfortunately, there is no one associated with the Tooth Fairy Project that
has an understanding of environmental transport.

In general, Sr-90 is bound in the top lauerys of the soil making it
available for root uptake. Florida, because of high rainfall levels, tends
to have soils that are mineral deficient. As a result plants tend to
scavenge available minerals including chemical congeners such as cesium and
strontium as replacements for potassium and calcium.

For megaton surface shots upwards of 95 percent of the radioactive yield is
inserted into the stratosphere. With a mean life of 40 years, there is still
new Sr-90 deposition occurring from stratospheric fallout. This is certainly
true for cesium and most likely true for strontium.

There are discontinuities in the tropopause, one depending on the season
occurs at 30 degrees north and south latitude. There is a greater transfer
of material from the stratosphere to the troposphere at this point with a
general downward circulation resulting in higher transfers of material from
the stratosphere to the ground at these latitudes.

If someone from the tooth fairy project is reading this, I would suggest
that you pick up a copy of Environmental Radioactivity, Eisenbud & Gesell.
