suggests that the overall representativeness of the data is good.
3.
Transport of debris from regions of higher ratio in either the
troposphere or stratosphere.
Figures 1, 2, and 3 clearly eliminate
this possibility in that from mid-1968 there are no other data in
either the stratosphere or surface air of either hemisphere with
ratios as high as the anomalies under consideration.
In view of our
conclusion regarding the representativeness of the data, it appears
that there are no hidden compartments cr pockets in the atmosphere
containing unexpected debris.

Tropospheric injections of Pu-239.
A few major injections of
Pu-239 in 1968 could theoretically have produced the high Pu-239/Sr-90
Observed from mid year onward.
The actual amount of “excess® Pu=-239
in the surface air during the pericd of the anomaly, that is the
amount not accountable as coming cut of the stratosphere, was estimated by using average ratics and Sr=-90 concentrations.
