Nuclear energy vocab

alpha particle Positively charged particle emitted by various radioactive materials during decay. It consists of two neutrons and two protons. They moves relatively slow, and can be stopped by most solid objects.
beta particle high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei during decay
chain reaction a chemical reaction or other process that spread or cause other reactions.
daughter isotope the remaining nuclide left over from radioactive decay.
decay curve A graph line representing the decrease of radioactivity with the passage of time.
fission a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts
fusion a nuclear reaction or a radioactive decay process in which the nucleus of an atom combines to form a bigger nuclei
gamma radiation electromagnetic radiation of high-energy photons. It's very penetrative, and is harmful to organics.
half-life The amount of time it takes for a nuclei to decay completely.
isotopes atoms that have the same number of protons, but different numbers of neutrons.
mass number is the total number of protons and neutrons in an atom
nuclear equation an equation to describe nuclear reaction
nuclear reaction the process in which two nuclei, or a nucleus of an atom and a subatomic particle collide to produce one or more nuclides that are different from the nuclide(s) that began the process
parent isotope an atom that undergoes decay to form a daughter isotope
radiation emission or transmission of energy in the form of waves or particles
radioactive decay
radiocarbon dating a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
