Radioactivity From Crossroads Baker Shot
The curves of Figs. 3.26, 3.27, and 3.28 ehow the radioactivity
in the surface waters of Bikini Lagoon on the firat three days after
Crossroads Baker i
The values shown ere in mR/hr.
Since this
shot was in late July, wind and current conditions were somewhat
different than those to be expected in March and April, when the
trade winds are blowing.
The prevailing trade winds are from east-
northeast, averaging 15 to 20 kmote, while on B day there were light

On
B +1 the light breezes alternated with periods of calm, and on B + 2
and B + 3 the wind increased somewhat and hauled to the southeast,
