A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays.

These samples usually undergo acid/base/acid pretreatment (AAA) prior to graphitization.

Acid/base concentrations, temperatures, and times are sample specific.

These samples usually undergo a light acid etch (AE) pretreatment.

These samples may require local reservoir correction in some cases, so a Delta-R value may be necessary.

Groundwater can also be analyzed for stable isotopes such as 18O and deuterium.
