Nature of Hazards
&
“hen an etomic bomb explosion occurs, tremendous quantities of energy
in a variety of forms are released.
This energy is propagated outsarc in
all directions.
b.
The immediate reaction is intense emission of ultraviolet, visible
and infrared (heat) radiation, gamma rays and neutrons,
coapanied by the formation of a large ball of fire.
This is ec-
A large part of
the energy from the explosion is emitted es a shock wave,
The ball of
fire produces & mushroom-shapped mass of hot gases, the top of which
rises rapidily.
left.
In the trail below the mushroom cap, a thin column is
Ine cloud and column ére then carried downwind, the direction anc
spéed being determined by the direction end speed of the wind zt the ver
ious levels of air from the surface to base of mushroom cap.
Part of
the energy from the explosion results in an ocean surface wave which is
considered of minor nature directly tc the Task Force,
¢.
All personnel of tle Task Force will be well outside of the ranse
of all hazard at the time of detonation, except for the light from the
fire deli,
The light of explosion is so dntense that permenent injury io
the cye may result from viewing the bell of fire at close ranze wiith the
naked eye or through binoculers,
Ordinary dark glasses will not suffice
and al? personnel whe do not have the special protective glasses, which
will be issued in limited numbers by CTG 7.1, .mst be facing 1&0 dugrees
from the detonation with the eyes closed,

POE ARCHIVE
The emission of dangerous nuclear radiation can be separated into
two time periods,
The primary radietion which occurs. at the tine of the
flash is composed of gamma rays and neutrons.
