The relative abundances of the stable isotopes of the elements are not entirely constant. for example, in some geologic samples (soils and rocks) the ratio of 87sr to 86sr is affected by the presence of a radioactive isotope of another element, which slowly undergoes β decay to produce more 87sr. what is this other isotope?
