USES OF NUCLEAR ENERGY

Introduction

Generally it is believed that nuclear


energy is used for destructive purposes
only. But, in fact it has more positive uses
than its negative uses. Basically atom is
the source of nuclear energy. This energy
is released by splitting of a nuclei in to
two.
Fission

The spontaneous or
induced splitting of an
atomic nucleus into
smaller nuclei, usually
accompanied by a
significant release of
energy.
Nuclear Radiations
 Alpha Particles
Positively Charged particle & Heavy as
compared to other particles
 Beta Particles
Negatively charged particle & more
penetrating as compared to Alpha
 Gamma Radiations
No Charge, highly penetrating radiations
Radioactive Isotopes
Elements can be made radioactive
by bombarding them with neutrons.
The atoms of the elements so
bombarded capture these
neutrons, thus form a different
nuclei called radio isotope. These
radioisotopes have unstable nuclei,
and dissipate excess energy in the
form of gamma and other rays.
Medical Uses
 In isotope scanning, a radioisotope is
introduced into the body, usually by means of
intravenous injection. The isotope is then taken
up in different amounts by different organs. Its
distribution can be determined by recording the
radiation it emits, and through charting its
concentration it is often possible to recognize
the presence, size, and shape of various
abnormalities in body organs.
 The human body organs effected by cancer are
treated with nuclear radiations called
Radiotherapy. Effected cells are killed by this
process.
Use in Agriculture
 Technical advancement in nuclear
technology has helped in the
production of crops seed having more
crop production and safe from insects
and other illness.
 Nuclear radiations helps to preserve
fruit and vegetable for a longer time.
 This also helps in analyzing soil type
and gives information to enhance its
quality.
Production of Electric Power
 Production of Nuclear power is
similar to other plants with the
difference that nuclear energy
is used for the production of
steam that rotates the turbine
blades with its exhaust.
Atomic Bomb
 The bomb producing shock waves and
heat and radiations due to fission.
 The energy produced is malisons time
greater the conventional TNT weapon.
 The atomic bomb has been used only
twice in warfare. The first was at
Hiroshima in1945. In an instant, 66,000
people were killed and 69,000 injured by a
10-kiloton atomic explosion.
 On August 9, 1945, Nagasaki fell to the
same treatment with a Plutonium bomb. Its
targeted only a mile and a half, but it still
leveled nearly half of the city. In few
seconds, Nagasaki's population dropped
from 422,000 to 383,000. Over 25,000
people were injured.
