Definitions for "Fission products"
Nuclides produced either by fission or by the subsequent decay of the nuclides thus formed.
The two smaller atoms produced as fragments when a large atom is fissioned. The size of these fragments varies, producing a cocktail of many different atoms. See reprocessing.
Light atoms that result from fission. The combined mass of fission products is less than that of the original whole atom because energy and neutrons are released.
