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...

Student Exploration: Nuclear Reactions [Note to teachers and students: This Gizmo was designed as a follow-up to the Nuclear Decay Gizmo. We recommend doing that activity before trying this one.] V ocabulary: chain reaction, CNO cycle, catalyst, deuterium, electron volt, fission, fusion, isotope, nuclear reaction, positron, positron emission, proton-proton chain Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The chart to the right gives the isotope name, element name, number of pro...

Radioisotopes and Radiation Protection Sherer - Q&A 2024 Update Chapter 15

Levels of stress hormones and stable isotope ratios in animal tissues are increasingly recognized as important tools in studies on the physiology and ecology of wildlife (e.g. Kempster et al., 2007; Barger and Kitaysky, 2011; Deschner et al., 2012; Bryan et al., 2013). Keratinous tissues, such as hair and feathers, offer the longest record of an animal’s circulating glucocorticoid (GC) concentrations (Bortolotti et al., 2009; Macbeth et al., 2010; Jenni-Eiermann et al., 2015). Steroids...
