In this type of decay, a negatively charged beta particle and a neutrino are emitted from the nucleus.

The atomic number increases by one and the neutron number is reduced by one.

any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product.

A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.

Because of their stable evolution in groundwater, such naturally occurring isotopes are useful hydrologic tracers, allowing evaluation of large geographic areas to determine flowpaths and flow rates.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.

Radioactive isotopes are nuclides (isotope-specific atoms) that have unstable nuclei that decay, emitting alpha, beta, and sometimes gamma rays.

Such isotopes eventually reach stability in the form of nonradioactive isotopes of other chemical elements, their "radiogenic daughters." Decay of a radionuclide to a stable radiogenic daughter is a function of time measured in units of half-lives.) decay results from an excess of mass.
