ABSTRACT
A world-wide network of gummed film stations was established
to monitor fallout following Operation Castle, Although meteorological data were poor, a general connection of troroscheric flow
patterns with observed fallout was evident.
There was a tendency for
debris to remain in tronical latitudes, with incursions into the
temperate regions associated with metecrological disturbances of the
predominantly zonal flow. As the season advanced, such incursions
became more evident.
Outside of the tropics, the southwestern Uni ted
States received the greatesttotal fallout,about five times that
received in Japan.
...
. The maximum fallout. on any day at an individual station in the |
United States, corrected to sampling day, was 200,000 a/m/tt2,
It is concluded that the probability of early fallout in
inhabited regions would be reduced by holding Pacific test series
in the winter months.
