:59:03
Over here we have
a two inch diameter ord.
:59:07
Also uranium 235.
:59:10
Now when the rod is rammed into
the heart of the fissionable core
:59:14
the mass
:59:14
of the two together rises beyond
the critical threshold.
:59:18
And that's when things start
to get exciting.
:59:21
The fissionable core will explode only
if at the moment of criticality
:59:24
it's bombarded by a blizzard
of neutrons and the blizzard
:59:27
is created by the initiator. . .
:59:30
Lithium. . .
:59:31
And polonium. . .
:59:33
what is it that wends the plug down
the tube into the mass?
:59:37
any old plastic explosive.
I believe you know about that.
:59:42
so what we're looking for
is some plastic explosive
:59:45
a detonator tow small discs a tube. . .
:59:50
A round metal case and a rod of uranium
:59:54
And the uranium ball.
:59:56
The thing about uranium, it's heavy.
:59:58
Twice as heavy as lead.
1:00:00
That ball alone would take
a strong man to life two handed.
1:00:04
But in size it's about as big as
a small football?
1:00:08
Nearer a child's football.
1:00:35
If an atomic bomb explodes on
an american base they'll be blamed
