What Wikipedia says

In physics, isotopic abundance is the amount of one particular isotope of a chemical element as a fraction of all the atoms in that element in a sample. In a sample representing the naturally occurring isotopes, it is called the natural isotopic abundance, or natural abundance (NA) when the context is clear.
