Isotop - Study guides, Class notes & Summaries

Understand the Environmental Processes That Control Groundwater Quality The integration of environmental isotopes with geochemical studies is now recognized as a routine approach to solving problem s of natural and contaminated groundwater quality. Advanced sampling and analytical methods are readily accessible and affordable, providing abundant geochemical and isotope data for high spatial resolution and high frequency time series. Groundwater Geochemistry and Isotopes provides the theoretical...

Option 1: While we often think of radiation as dangerous, radioactive isotopes are widely used in the field of healthcare as well as in many other fields. For your initial post, choose a radioactive isotope used in healthcare or another field and report on how your isotope is used. Be sure to answer both of the following questions as part of your initial post: a. What type(s) of radioactive decay does your isotope undergo? b. How is your isotope used? Use at least one outside source and ci...
