nu·cle·ar en·er·gy

• The energy released during nuclear fission or fusion, esp.
• when used to generate electricity
• It can be used to create electricity but it must first be released from the atom.
• Power plant is a seriers of machines that can control nuclear fission to produce
• Electricity.

Nuclear Energy
Atoms are tiny particles that make up every object in the universe. Nuclear energy is energy in the nucleus (core) of an atom. There is enormous energy in the bonds that hold the nucleus together. Energy is released when the bonds are broken.

Nuclear energy can be used to make electricity, but first it must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission.

Nuclear Fuel — uranium
The fuel most widely used by nuclear plants for nuclear fission is uranium. Uranium is nonrenewable, though it is a common metal found in rocks around the world. Nuclear plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart. Though uranium is quite common, about 100 times more common than silver, U-235 is pretty
rare.

NUCLEAR MEDICINE

• It uses radiation to allow doctors to make quick.
• It allows them to be accurate and diagnosis of the functioning.
• Radiotherapy can be used to treat some medical conditions.

RADIOTHERAPY

• Over 10,000 hospitals use
• Radioistopes in medicine and about
• 90% of procedures are for diagnosis.
