Dear Ken,

>     Nickel 60 is a stable element and not an isotope. 

    Nickel 60 is one of five stable isotopes of the element nickel.
    Isotopes are just different types of a given element, with different
    mass numbers due to the fact that they have different numbers of
    neutrons (but the same number of protons). The overall mass number
    of an element is calculated using the different masses of the
    isotopes and their percentage abundance. 

    The word isotope does not indicate radioactivity. Just splitting
    hairs but nickel 60 is indeed one of nickel's isotopes.
