and activities of Task Unit 7,
Task Group
Joint Task Force SEVEN, during Operation Redwing.
Task Unit 7 was charged with the responsibility of
providing radiological-safety support for the Scientific
Task Group, TG 7.1. The various chapters are devoted to
a discussion of the activities engaged in by the Task
Unit and the organization necessary to provide adequate
radiological-safety support for a weapons-test operation
of the magnitude of Operation Redwing.
Radiological-survey results of the atolls following
firing of the various devices are presented. Special

Five KING-simulation calculations were carried out
on digital computers with 2D radiation-hydrodynamic code
SN-YAQUI using the KING yield (540 kt) at altitudes
124, 248, 450 (event), and 1000 m. The 1000-m KING

fireball interacts only mildly with the groundreflected shock,

KEYWORD(S)
and evolves
into a normal torus
structure by 10s. The 450-m KING has a more intense
interaction, which creates an exceptionally prominent
skirt. The 124- and 248-m fireballs develop reverse
vortices and hug the ground for some time. The 124-m
KING also forms a very luminous Mach stem. The surface
KING stays on the ground for {approx_equal} 5 s, and
then rises; a normal torus is seen by {approx equal} 15
s. The time of appreciable fireball flattening, and the
times of minimum and second maximum are height-of-burst
dependent quantities. (U)
