our country and all its people
could be in danger of nuclear attack
in minutes by enemy missiles
in hours by enemy aircraft
our cities
hog farm
our factories
prime target would be our air base
with all our aircraft on the ground
our weapons of interception or
retaliation not instantly available
we might face another and infinitely
more costly
pearl harbor
'em
to avoid dr disasters
some of our aircraft must always be in
the sky or on the alert
carrying nuclear weapon
these weapons are always unharmed
they will be harmed only following
decision by the president of the united
states
formally the israeli aircraft
with nuclear weapons conform operas line
deterrent force indeed don
our shores striking force in case of the
fact
d
we'd be american people
understand
and exam
business entity veronica vinyl
but we want to know the backed by bob
one question
doing live in danger of nuclear
explosion and radioactive fallout
it's one of the bill clinton clash
for one of these nuclear weapons
accidentally dropped
did give you the facts
the united states air force present
really bomber carries a nuclear weapon
it is a well designed carefully
maintained skillfully blown airplane
bob airplanes just like it
crash and burn
there was no nuclear explosion
no radioactive fallout
are the facts
the bombardier watches over controls as
a bit human ingenuity can make them to
prevent accidental mom release
but nuclear weapons have been dropped
inadvertently there was no nuclear
explosion
no radioactive fallout
these are the back
and specially instrumented aircraft
verify these back in a continuing
nuclear safety program
that ken starr nuclear weapons under
controlled conditions
simulate every conceivable hazard
might go to this nuclear safety program
is therefore special weapons either at
albuquerque new mexico
in ultra modern laboratory buildings
works scientists in and out of uniform
they work with the incredibly complex
equations of nuclear physics which
derive from feinstein's famous
relationship of mass to energy
these cryptic figures
programmed into lightning fast computers
uh... the theoretical based upon which
these scientists together with those of
the atomic energy commission
and build nuclear weapons safety
by research
design development
and laboratory tests
they insure weapons not yet bill
against an accidental nuclear explosion
they have been doing this successfully
since nineteen forty five
in safety conferences with other defense
department agencies and the atomic
energy commission
in thirteen years there've been a few
accidents but not one
has resulted in nuclear explosion or
radioactive fallout
these are the facts
what keeps our nuclear weapons safe
to understand why there has never been
an accidental nuclear explosion
you must first know-how these explosions
can be produced
p general principles of nuclear
explosions
any explosion is the result of a very
rapid release of a great amount of
energy
congressional explosions result from the
rearrangement of for adams
in some explosive material
for example in theory of the
rearrangement of poland's of hydrogen
carbon
nitrogen and oxygen
produces explosive force
on the other hand
nuclear explosions result promo
rearrangement within feature
this might be by joining together or
fusion as in an age from
all week splitting apart
or fishing
as in an eva
at present space bomb explosion starts
with vision
solis putting all the nucleus of the apt
is the basic principle of nuclear
weapons
all matter is composed of one or more of
the one hundred other elements
ollie is the arrows of the meadows you
radio and left on him
convenience really pushing to cause
nuclear explosion
these elements are mildly radioactive
they met shorter range low penetration
of the particles while in their own fish
in st
these awful particles do not have the
harmful effects of the longer-range in
stronger gamma rays
which are given off by certain elements
such as radio more buy the products of
nuclear fission
the arms of uranium and plutonium are
among the heaviest
heavy because the nucleus of the jet and
contains large numbers of the
fundamental particles called protons and
neutrons
when i'm free neutron hits this nucleus
splits into two parts
releasing more neutrons which may go on
to split other nuclei
the resulting fission products become
highly radioactive
committing the long-range in dangerous
gamma rays
this what nucleus weighs less than the
whole point
and this difference in weight is
released in the form of energy
nuclear energy
after fishing harmful gamma radiation
before fishing
innocuous alpha
radiation
to build up a nuclear energy release
the fissionable material must be of a
certain size shape for density
then one of the neutrons escaping from a
split atomic nucleus will interns split
another
and a chain reaction is set up
the masses now releasing nuclear energy
but not quickly enough to cause a
nuclear explosion
this condition is called critical
if the masses now suddenly increased
so that more neutrons are trapped each
time an atomic nucleus is split
uh... multiplying chain reaction is
maintained
now the masses supercritical causing a
nuclear explosion
them so they have the fissionable
material can be as important as mass in
building up a nuclear explosion
the same stared can be compressed
sold at the adams are closer together
and neutron split more atomic nuclei
making these smaller mass critical
if compressed still more
uh... multiplying chain reaction sets in
causing the mass to become supercritical
in a nuclear explosion
nuclear weapons make use of both of
these principles
i've gotten type device can increase the
mass of fissionable material to a super
critical state instantaneously
once i'm critical mass is propelled
forcibly into another by an ordinary
parker charge
the increased mass becomes supercritical
multiplying chain reaction bills up
until
the nuclear explosion
obviously if any mechanical device keeps
these two sub critical mass is apart
the weapon is nuclear safety
applications of this fact prevent
accidental nuclear explosions in gotten
type weapons
another kind of nuclear weapon is the
implosion type
it compresses the fissionable material
to greater density to make it
supercritical
to do this this paris in close by a
shell of ordinary explosive designed a
direct its explosive force n_-word
this effect is called implosion
the detonators attached to the explosive
are connected to a complex firing device
which can fire every detonators
simultaneously
when all the explosive is that related
simultaneously
the nuclear material is compressed into
a super critical mass
which results in a nuclear explosion
implosion type weapons are nuclear safe
because only the specially-designed
firing device
can produce the simultaneous detonation
of all the ordinary explosive
a deliberate effect possible only by the
precise firing mechanism
jonas angled at a later be fired
accidentally whether by
malfunction crash impact or fire
the explosive would not provide the
all-around compression necessary for
implosion
instead it might push the nuclear
material out of the shell
breaking into small pieces or eventbrite
this sound fission material and that's
only a powerful particles because no
nuclear explosion has taken place
these up articles do not penetrate the
skin
the simplest precautions can prevent
darien taken to the body
and the simplest cleanup measures can
remove them
so you see each type of nuclear weapon
has its own sake there's against
accidental nuclear explosion
these
artifacts
and they are based upon practice as well
as the area
specially instrumented aircraft ply the
tests that verify what happens inside a
weapon
what accident hazards the nuclear
components may have to withstand
nuclear safety is everybody's business
although air force flies the test
missions
scientists and technicians from the
atomic energy commission and other
services
man the test range and evaluate the
findings of the elaborate
instrumentation
brown's list measure impact
characteristics of various weapons like
pair maybe without nuclear components
so that this president aerial is not
wasted
they supplement the destination tests
that have been made with the complete
nuclear weapons
impact
rorschach
does not cause nuclear explosion or
radioactive fallout
one has exploded is the ordinary
explosive which is an essential part of
nuclear weapons
the ordinary explosive in a nuclear
weapons can be a hazard
exactly as in a conventional bomb
depending upon the amount and location
of the explosive
and the speed of height of the drop
we may experience a variety of ordinary
explosion
large ones
small ones or none at all from him
fact of the bomb
beside the hazard if in fact frequent
tests are run palmer has of the fire
to learn what temperatures and pressures
would be created inside a weapon by an
aircraft fired
various types of bombs are subjected to
a flame bad of burning fuel
because firewood also destroy the
pressures nuclear materials it is
replaced by instruments
their readings are compared with known
characteristics of the fissionable
material
to assure the temperatures higher than
any aircraft fire will not set off a
nuclear explosion
the characteristic lifeline indicates
that the ordinary explosive his burning
in the web
sometimes the explosive detonators
because of close on the line and
intensity
petals of such explosions are measured
and compared with those in an actual
nuclear weapons
prior and ordinary explosives do not
create the conditions necessary for
nuclear explosion
these are the facts
and i'm a vast desert ranges of the
atomic energy commission
the facts are verified by safety testing
live prototypes of all new weapons
before they go into production for our
stockpiled
the tests are costly in money and
manpower
even more costly in the fissionable
materials on which our nuclear strength
depends
lot they do provide insurance against
nuclear accidents
which make them a bargain at any price
some take place deep in the earth
fantastically complex instruments
replace the five senses
they record what happens when some of
the explosive that surrounds the nuclear
material of a new weapon is deliberately
decimated
they record only an ordinary explosive
blast
a random detonation has not created the
implosion which would compresses the
nuclear materials to a super critical
mass
there was no one nuclear explosion
knoll radioactive fallout
each new design must be proved
nuclear safe
able to withstand accidents
or random explosive
other tests with nuclear weapons are
made above ground
these are also designed to test a
nuclear safety of new weapon types by
intentionally decimating the explosive
which surrounds the fissionable material
and
sometimes these tests also provide data
on the side effects to be expected
if the fissionable material is broken up
by the explosion
air samplers and test pads are used to
gauge the area
intensity and duration of the east side
effects
in this way they learn not only what
does not happen when the charges
deliberately fired
rot what does
the explosive does break up the nuclear
material and scatter parts of it over a
small area
this fissionable material is mildly
radioactive
if the explosion or fire should suspend
any of this material in dust or small
it should not be inhaled or otherwise
taken into the body in quantity
that is why the train monitoring and
clean up crews may wear respirators
until air samplers or alpha counters
have determined that no injurious
concentration exists
the alpha particles emitted do not
penetrate skin or clothing so this
material is harmless one on the ground
only simple clean up measures are
necessary plus an effort to find and
save the valuable material
the findings from all test setup to
measure possible radiological hazard are
no external radioactive hazard from
material on the ground
slide radioactive hazard from prolonged
in relation of material suspended in a
small area near the accident
but not in
from the short exposures necessary for
firefighting rescue
or clean up of the small area involved
these are the fact
facts that have dispelled the fearsome
myths about accidents involving nuclear
weapons
for anyone near an accident whether or
not the crashed airplane carries a
nuclear weapon
here are the safe and simple rules
stay away from the crash unless you are
needed for rescue bystanders endanger
themselves and hamper others to be safe
keep at least a quarter of a mile away
from any vernon airplane
at this distance u_s_a_ from the flames
which makes both the jet fuel from
detonating explosives and from flying
debris
these are the real dangers in rescue or
fire hasn't always been there
and if necessary cleaned up by specially
trained teams
other specialist care for burned or
underestimated pieces of ordinary
explosive
until this is done
access to any crash area is controlled
to prevent accidents and speed up the
work
the test you have seen improved the
safety of our nuclear weapons program
over and over again
but the grim reality is the payoff
house save is a nuclear bomber coming in
for a crash landing
sn though bound he had to be crash
landing nor the fire which often follows
not even decimation of the ordinary
explosive in the west and cause nuclear
explosion for radioactive fallout
the safety it was designed in during
research
built-in during development
proved in the laboratory and on the
range
has withstood the ultimate
tragic test
these are the back
they proved that you the american people
in st paul st
and strong
because the weapons your air force must
carry have been tested nuclear saying
the possibility of an accidental nuclear
explosion he is also on
has to be practically non-existent
strong because an air force nuclear arms
and combat ready stands guard against
surprise attack
under the shelter
you and your family made live in peace
freed from the fear of nuclear accidents
