Periodic Table

An "image map" periodic table and short notes about many isotopes and their applications has been created to help illustrate the uses of assorted isotopes in hydrology, geology, and biology. More thorough contributions are very welcome.

Operation: To obtain information about a specific element in the period table below, click on the "button" of that element. Only elements in yellow are currently enabled. NOTE: you must use a graphics-capable browser to view the image map; otherwise, you must use the alternative access page.  To search for specific information using keywords, you may also use the local search engine.
