Unstable Nucleus An unstable nucleus releases energy by Radioactive decay

Nuclear radiation Gamma ray- have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. Alpha rays- consist of two protons and two neutrons bound together into a particle identical to a helium nucleus, which is produced in the process of alpha decay. Beta rays- are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei such as potassium-40.

Radioisotope The ratio of neutrons to protons

Half life's The amount of time required for half of the atoms in a radioactive substance to decay naturally

Nuclear Chain reaction When a nuclear reaction causes and affects one or more nuclear reaction

Used fuel Rods Appreciated heat being produced in spent fuel, after it is unloaded due to the radioactivity of the fission products and needs to be cooled.

Fission and Fusion Fusion- the splitting of an atom Fusion- is the bonding of an atomic nuclei or nuclear particles; to create a bigger or heavier atomic nuclei

Detecting radioactive material Geiger counter- a type of particle detector that measures ionizing radiation. Dosimeter-measure an individual's or an object's exposure to something in the environment — particularly to a hazard inflicting cumulative impact over long periods of time, or over a lifetime. Scintillation counter-The sensor called a scintillator, consists of a transparent crystal, usually phosphor, plastic anthracene, that fluoresces when struck by ionizing radiation.

Medicines To derive information about the functioning of a persons specific organs, or to treat disease.
