Nuclear Energy

Front

What is Fission?

Back

Fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy. It typically involves heavy elements like Uranium-235.

What is Fusion?

Back

Fusion is a nuclear reaction where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy. It occurs naturally in stars, including the sun.

Front

What is Radioactive Decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This occurs when the nucleus of an isotope is unstable.

Front

What is Uranium Enrichment?

Back

Uranium enrichment is the process of increasing the percentage of Uranium-235 in uranium, making it more suitable for use in nuclear reactors and weapons.

What type of radiation can be stopped by a 5 mm piece of aluminum?

Back

Beta radiation can be stopped by a 5 mm piece of aluminum.

Front

What is Alpha Radiation?

Back

Alpha radiation consists of alpha particles, which are made up of 2 protons and 2 neutrons. It is the least penetrating type of radiation and can be stopped by a sheet of paper.

Front

What is Beta Radiation?

Back

Beta radiation consists of beta particles, which are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.

Front

What is Gamma Radiation?

Back

Gamma radiation is a form of electromagnetic radiation of high energy and short wavelength. It is highly penetrating and requires dense materials like lead for shielding.

Front

What is a Chain Reaction?

Back

A chain reaction is a series of reactions where a reactive product or by-product causes additional reactions to occur. In nuclear fission, one reaction produces neutrons that can trigger further fission reactions.

Front

What is the role of Uranium-235 in nuclear energy?

Back

Uranium-235 is a fissile isotope used as fuel in nuclear reactors. It can sustain a chain reaction, releasing a large amount of energy.
