A Detailed Discussion of the Occurrence of Strontium? and Cesium!”
in the Atmosphere, Biosphere, and its Uptake and Behavior in Man (oral,
inserts, and bibliography) NOTE: Sr?% will be outlined in detail below
A,
Distribution, storage time, and fallout rate from atmosphere
1.
Combination of local and world-wide fallout of sr70
resulting from fractionation; long half-life; stratospheric
holdup and mixing; decay
B.
Deposition on soil and plants ~- variations of Sr90 level in
environment as a result of weapons detonated in a relatively
short period of time - from a few months to two or three years
C,
l.
Predicted fallout as a function of mixing and time
2.
Effects of retention of fallout on surfaces of vegetation
The calcium model as a basis for predicting Sr?0 behavior
1.
2.
Similarities and differences in behavior in the biosphere
and in man
