Ma.CHELL:
Was there any final assay of the soil after you got through
harvesting the crops?
LARSEN:
Yes, we feel that quite significant quantities appeared.
I
don't have the figures with me right now,
BEYHEs
The 196 atcrocuries were distributed over how?
LARSEN s
Four square feet.
MITCHELL:
How do you account for such # large drop fran the first crop
to the last one if the radioactivity in the sell is ssinteined?
LARSENs
Well, by decay curves and energy curves, the anly thing that
we have been able to pick up here is Strontium 09.
It has
been a selective sbeorption, ff apparently. Wow we inow from
other crop datg that we have done where we have taken soils,
agricultural solid from throughout California and New Mexico
and contaminated at the rate of 100 disintegrations per sennd
per gram of soil, there are 1600 grams to a plot.
you some idea of what happena here,
I can give
On the Strontium if we
take the soil to the plant end we also try to cover this up
with the animal feeding, there sre 100 disintegrations
initially per gram. "he plan in the leaf material which the
bean was the zest inportent, the barley wae the lesst important
and had 1420 disintegrations per second per gram af plantdry
material and if this plent were fed to this animal our
experinents have netted 200 d per s retained this would be of a
dose fed.
In other words, Y got these figures from another
