WebIsotope hydrology uses both stable and unstable isotopes. Stable isotopes are non-radioactive, meaning they don’t emit radiation. Unstable isotopes (or radioisotopes) undergo radioactive decay and are therefore radioactive. Here is a simple overview of how the science of isotope hydrology works. Origin and transport of water in the water cycle WebStable isotope analysis has emerged as one of the primary means for examining the structure and dynamics of food webs, and numerous analytical approaches are now commonly used in the field.
