This section provides access to a number of visualizations and supporting material illustrating the concept of radioactive decay and its central role in radiometric dating. Visualizations include cross-linked series of diagrams, static illustrations, and photos.
Radioactive Decay Interactive Histogram and Animation. (more info) An interactive histogram illustrating radioactive decay allows the user to alter the half-life time of the field of nuclei shown in an accompanying animation.
Dating Rocks. (more info) From the Dynamic Earth at the University of Leeds, a cross-linked series of static diagrams illustrates the underlying principle of radioactive decay, the concept of a decay constant, and isochron plots.
Radiometric Time Scale. (more info) A brief treatment of the subject of radiometric dating from the USGS using explanatory text, tables, and photos to explain the history of the discipline and the basic concepts.
