CONTINUED DEVELOPMENT OF MIKE CLOUD
MIKE cloud has "’splashed'' against the base of the stratosphere
about six minutes after detonation.
One of ‘the most significant de-
toils in this photograph Is the appearance of the “‘plume’’ above the
laterally spreading canopy.
Theoretical analysis of bomb clouds (see
Section I!) would Indicate that most ‘of the ‘radioactive ‘debris ‘would
be contained in this “Splume’’.
Results of the cloud sampling pro-
gram would tend to establish this ‘conclusion, and Indicate a fundamental operational diffleulty. |
The canopy {s ‘now approaching Its maximum dimension, some
seventy fo eighty miles in diameter.
