Isotopes

Medical Definition: Atomic species differing in mass number but having the same atomic number. (Grant & Hackh's Chemical Dictionary, 5th ed)
Guide Notes: for stable isotopes only; GEN: avoid as IM; NIM as coord; Manual 25.20+; m for metastable = RADIOISOTOPES or specific pre-coord radioisotope
