The document discusses the differences between hydrogen bombs and atom bombs. It notes that a hydrogen bomb uses fusion reactions between light nuclei to create massive explosions, as occurs in our Sun, while an atom bomb relies on fission reactions of uranium or plutonium isotopes. The first hydrogen bomb test explosion occurred in 1952 and had over 1 million times the power of the atom bombs dropped on Hiroshima and Nagasaki. Hydrogen bombs pose a far greater threat due to their enormous destructive potential.

2.  In a fusion reaction, two light nuclei merge to
form a single heavier nucleus. The process
releases energy because the total mass of the
resulting single nucleus is less than the mass
of the two original nuclei. The leftover mass
becomes energy.
 Example: Hydrogen Bomb, Sun

5.  The Soviet Union started development with their own atomic
bomb project, and after that developed even more powerful
fusion weapons called "hydrogen bombs."
 During the Cold War, the Soviet Union and United States each
acquired nuclear and placing many of them onto rockets
which could hit targets anywhere in the world.
 The first hydrogen bomb was exploded in November 1952 in
Marshall Islands.
 In 1953, Russia exploded a powerful hydrogen bomb having
power of 1 million tonnes of TNT.

6.  Hydrogen Bomb explosion produces blast, light, heat, and varying
amounts of fallout.
 The concussive force of the blast itself takes the form of a shock wave
that radiates from the point of the explosion at supersonic speeds and
that can completely destroy any building within a radius of several miles.
 The intense white light of the explosion can cause permanent blindness
to people gazing at it from a distance of dozens of miles.
 The explosion’s intense light and heat set wood and other combustible
materials burning at a range of many miles, creating huge fires that may
coalesce into a firestorm.
 The radioactive fallout contaminates air, water, and soil and may
continue years after the explosion.

7.  Atom bomb is a powerful explosive nuclear
weapon fuelled by the splitting, or fission, of
the nuclei of specific isotopes of uranium or
plutonium in a chain reaction.
 J.Robert Oppenheimer was the "father of the
atomic bomb"

9. When a neutron strikes the nucleus of an atom of
the isotopes uranium-235 or plutonium-239, the nucleus
is split into two nucleus.
In the process of splitting, a great amount of thermal
energy, as well as gamma rays and two or more neutrons,
are released.
Under certain conditions, the escaping neutrons strike and
thus fission more of the surrounding uranium nuclei,
which then emit more neutrons that split still more nuclei.
This series of rapidly multiplying fissions culminates in
a chain reaction in which nearly all the fissionable
material is consumed, in the process generating the
explosion of what is known as an atomic bomb.

10.  A hydrogen bomb has the potential to be 1,000
times more powerful than an atomic bomb. Thus
hydrogen Bomb is most powerful nuclear bomb
ever made in the field of Nuclear Weapons.
 A hydrogen bomb has never been used in battle
by any country
 It’s test can bring severe destruction to the
environment around the earth.
 It require tremendous amount of temperature
which is very hard to achieve.
