About the Periodic Table...

This table (with information about the applications of selected isotopes) was put together by Carol Kendall, Eric Caldwell, and Daniel Snyder (U.S. Geological Survey, Menlo Park, CA). The text was gleaned from various papers and reference texts available in the Isotope Tracers Project (WRD), and hence is often biased towards watershed-related research. Assistance in providing a more balanced treatment of the topics is very welcome. Corrections, suggestions for improvement, and additional text and references should be sent to

Other Periodic Tables Available On-Line

Los Alamos National Laboratory has assembled a nice list of periodic tables.
