Emission of electromagnetic waves and/or subatomic particles
transmutation
transmutation
conversion of an atom of one element to an atom of another element

gamma ray
high-energy photon with no mass or electrical charge
fusion
fusion
reaction in which two light nuclei combine to form a nucleus of greater mass
alpha particles
alpha particles
positively charged particle consisting of two protons and two neutrons
positron

nucleon
nucleon
a constituent (proton or neutron) of an atomic nucleus
nuclide
an atom that is identified by the number of protons and neutrons in its nucleus
radioactive decay
radioactive decay
the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation
radioactive decay
measurement of the amount of radioactive material (usually carbon 14) that an object contains
