PREFACE
When "The Effects of Atomic Weapons" was published in 1950, the explosive
energy yields of the fission bombs available at that time were equivalent to some
thousands of tons (i.e., kilotons) of TNT. With the development of thermonuclear
(fusion) weapons, having energy yields in the range of millions of tons (i.e.,
megatons) of TNT, a new presentation, entitled "The Effects of Nuclear Weap­
ons," was issued in 1957. A completely revised edition was published in 1962 and
this was reprinted with a few changes early in 1964.

Since the last version of "The Effects of Nuclear Weapons" was prepared, much
new information has become available concerning nuclear weapons effects. This
has come in part from the series of atmospheric tests, including several at very high
altitudes, conducted in the Pacific Ocean area in 1962. In addition, laboratory
studies, theoretical calculations, and computer simulations have provided a better
understanding of the various effects. Within the limits imposed by security re­
quirements, the new information has been incorporated in the present edition. In
particular, attention may be called to a new chapter on the electromagnetic pulse.

We should emphasize, as has been done in the earlier editions, that numerical
values given in this book are not—and cannot be—exact. They must inevitably
include a substantial margin of error. Apart from the difficulties in making
measurements of weapons effects, the results are often dependent upon circum­
stances which could not be predicted in the event of a nuclear attack. Furthermore,
two weapons of different design may have the same explosive energy yield, but the
effects could be markedly different. Where such possibilities exist, attention is
called in the text to the limitations of the data presented; these limitations should not
be overlooked.

The material is arranged in a manner that should permit the general reader to
obtain a good understanding of the various topics without having to cope with the
more technical details. Most chapters are thus in two parts: the first part is written at
a fairly low technical level whereas the second treats some of the more technical and
mathematical aspects. The presentation allows the reader to omit any or all of the
latter sections without loss of continuity.

The choice of units for expressing numerical data presented us with a dilemma.
The exclusive use of international (SI) or metric units would have placed a burden
on many readers not familiar with these units, whereas the inclusion of both SI and
common units would have complicated many figures, especially those with
logarithmic scales. As a compromise, we have retained the older units and added an
explanation of the SI system and a table of appropriate conversion factors.
Preface
Many organizations and individuals contributed in one way or another to this
revision of "The Effects of Nuclear Weapons," and their cooperation is gratefully
acknowledged. In particular, we wish to express our appreciation of the help given
us by L. J. Deal and W. W. Schroebel of the Energy Research and Development
Administration and by Cmdr. H. L. Hoppe of the Department of Defense.

CHAPTER I
GENERAL PRINCIPLES OF
NUCLEAR EXPLOSIONS

CHARACTERISTICS OF NUCLEAR EXPLOSIONS

INTRODUCTION

1.01 An explosion, in general, re­
sults from the very rapid release of a
large amount of energy within a limited
space. This is true for a conventional
"high explosive," such as TNT, as well
as for a nuclear (or atomic) explosion,1
although the energy is produced in quite
different ways (§ 1.11). The sudden
liberation of energy causes a consider­
able increase of temperature and pres­
sure, so that all the materials present are
converted into hot, compressed gases.
Since these gases are at very high tem­
peratures and pressures, they expand
rapidly and thus initiate a pressure
wave, called a "shock wave," in the
surrounding medium—air, water, or
earth. The characteristic of a shock
wave is that there is (ideally) a sudden
increase of pressure at the front, with a
gradual decrease behind it, as shown in
Fig. 1.01. A shock wave in air is gen­
erally referred to as a "blast wave"
because it resembles and is accompan­
ied by a very strong wind. In water or in *

the ground, however, the term "shock"
is used, because the effect is like that of
a sudden impact.

1.02 Nuclear weapons are similar to
those of more conventional types insofar
as their destructive action is due mainly
to blast or shock. On the other hand,
there are several basic differences be­
tween nuclear and high-explosive
weapons. In the first place, nuclear ex­
plosions can be many thousands (or
millions) of times more powerful than
the largest conventional detonations.
Second, for the release of a given
amount of energy, the mass of a nuclear
explosive would be much less than that
of a conventional high explosive. Con­
sequently, in the former case, there is a
much smaller amount of material avail­
able in the weapon itself that is con­
verted into the hot, compressed gases
mentioned above. This results in some­
what different mechanisms for the ini­
tiation of the blast wave. Third, the
temperatures reached in a nuclear ex­
plosion are very much higher than in a

'The terms ''nuclear'' and atomic" may be used interchangeably so far as weapons, explosions, and
energy are concerned, but "nuclear" is preferred for the reason given in § 1.11.

conventional explosion, and a fairly
large proportion of the energy in a nu­
clear explosion is emitted in the form of
light and heat, generally referred to as
"thermal radiation." This is capable of
causing skin burns and of starting fires at
considerable distances. Fourth, the nu­
clear explosion is accompanied by
highly-penetrating and harmful invisible
rays, called the "initial nuclear radia­
tion." Finally the substances remaining
after a nuclear explosion are radioac­
tive, emitting similar radiations over an
extended period of time. This is known
as the "residual nuclear radiation" or
"residual radioactivity" (Fig. 1.02).

1.03 It is because of these funda­
mental differences between a nuclear
and a conventional explosion, including
the tremendously greater power of the
former, that the effects of nuclear
weapons require special consideration.
In this connection, a knowledge and

understanding of the mechanical and the
various radiation phenomena associated
with a nuclear explosion are of vital
importance.

1.04 The purpose of this book is to
describe the different forms in which the
energy of a nuclear explosion are re­
leased, to explain how they are propa­
gated, and to show how they may affect
people (and other living organisms) and
materials. Where numerical values are
given for specific observed effects, it
should be kept in mind that there are
inevitable uncertainties associated with
the data, for at least two reasons. In the
first place, there are inherent difficulties
in making exact measurements of
weapons effects. The results are often
dependent on circumstances which are
difficult, if not impossible, to control,
even in a test and certainly cannot be
predicted in the event of an attack. Fur­

Newsletter - Die neue Aufrüstungskoalition

(Eigener Bericht) - Die Beschaffung von Kampfdrohnen durch die mutmaßliche künftige Regierungskoalition und voraussichtlich auch die Bestätigung der "nuklearen Teilhabe" durch SPD, FDP und Bündnis 90/Die Grünen rücken näher. Wie sich aus einem neuen Positionspapier einer SPD-Projektgruppe ergibt, zieht die Partei ihre bisherige Weigerung, Kampfdrohnen zu beschaffen, zurück und öffnet sich dem Vorhaben - unter dem Vorwand, es diene nur dem Schutz deutscher Soldaten. Mit dieser Begründung hatten bereits Bündnis 90/Die Grünen ihren Widerstand gestoppt. Auch bei der "nuklearen Teilhabe" haben längst Rückzugsmanöver begonnen: Während die SPD in all den Jahren ihrer Regierungsbeteiligung an der Option festgehalten hat, deutsche Tornados im Kriegsfalle auch US-Atombomben abwerfen zu lassen, hieß es bei Bündnis 90/Die Grünen zuletzt, man könne "nicht einfach sagen, wir schicken die US-Atomwaffen mal eben zurück in die USA". Die scheidende Verteidigungsministerin Annegret Kramp-Karrenbauer hat mit ihrer Ankündigung, bei Bedarf nukleare "Mittel" gegen Russland einzusetzen, einen diplomatischen Eklat ausgelöst.

OPINIA PUBLICZNA

MEMENTO


NAJPEŁNIEJSZĄ koncepcję demokracji stworzył
Frederick Grimke (1791 - 1864), autor pracy Rozważania na temat charakteru i tendencji wolnych instytucji . (Consideration Upon the Nature and Tendency of Institutions. Cincinnati 1848)) .... Filarem stworzonej przez Grimkego teorii demokracji była jego koncepcja opinii publicznej. Opinia mas jest słuszna i może stanowić podstawę polityki publicznej, -ponieważ - zdaniem Grimkego - ludzie mają wrodzone poczucie dobra i zła, a wykształcenie i cały nieformalny system prestiżu oraz potępienia społecznego dodatkowo sprzyjają konformizacji opinii.
Wrbrew p[oglądom de Tocqqueville`a, Grimke uwaźał jednolitość opinii za zjawisko korzystne, ponieważ jednostka może się mylić, pogląd ogółu ludzi stanowi natomiast odzwierciedlenie swoistej "opinii ludzkości".
Stąd prosty wniosek, że w celu zbliżenia się do prawdy w kwestiach publicznych należy nieustannie poszerzać liczbę ludzi uczestniczących w życiu politycznym.

Strange radio waves emerge from the direction of the galactic center

Astronomers have discovered unusual signals coming from the direction of the Milky Way's center. The radio waves fit no currently understood pattern of variable radio source and could suggest a new class of stellar object.

"The strangest property of this new signal is that it is has a very high polarization. This means its light oscillates in only one direction, but that direction rotates with time," said Ziteng Wang, lead author of the new study and a Ph.D. student in the School of Physics at the University of Sydney.

"The brightness of the also varies dramatically, by a factor of 100, and the signal switches on and off apparently at random. We've never seen anything like it."

Many types of star emit variable light across the electromagnetic spectrum. With tremendous advances in , the study of variable or transient objects in is a huge field of study helping us to reveal the secrets of the Universe. Pulsars, supernovae, flaring stars and are all types of astronomical objects whose brightness varies.

"At first we thought it could be a pulsar—a very dense type of spinning dead star—or else a type of star that emits huge solar flares. But the signals from this new source don't match what we expect from these types of celestial objects," Mr Wang said.

The discovery of the object has been published today in the Astrophysical Journal.

Mr Wang and an international team, including scientists from Australia's national science agency CSIRO, Germany, the United States, Canada, South Africa, Spain and France discovered the object using the CSIRO's ASKAP telescope in Western Australia. Follow-up observations were with the South African Radio Astronomy Observatory's MeerKAT telescope.
