Nuclear Reactions and Processes

Fusion is the joining of atomic nuclei to form a heavier nucleus, releasing energy in the process.

Gamma rays are a form of electromagnetic radiation with no mass and high energy.

Half-life is the amount of time it takes for half the nuclei in a sample of the isotope to decay.

Fission is the splitting of atomic nuclei into smaller parts, releasing energy.

Alpha radiation has the lowest penetrating power, can only penetrate 0.05 mm into the body, and can be stopped by the skin.

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

A nuclear reaction is a process in which two nuclei or nuclear particles collide, resulting in the release of energy and/or the transformation of elements.

A chain reaction is a series of reactions where a reactive product or by-product causes additional reactions to occur.

Fusion involves the joining of nuclei, while fission involves the splitting of nuclei.

Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles.
