CHEM120 Week 6 Discussion: Radiation – Radioactive Isotope: Cobalt-60 (Option 1) Option 1 Cobalt-60 a. What type(s) of radioactive decay does your isotope undergo? Radioactive decay occurs when an unstable nucleus changes into a stable nucleus by emitting radiation. The cobalt-60 isotope undergoes a beta decay and produces gamma rays as it decays. The half-life for cobalt-60 is 5.27 years. This is how long the decaying process takes to get to Nickel-59, a more stable isotope ("Cancer Therapy,...

Week 6 Discussion: Radiation Hello everyone, For this weeks discussion I will do option 2 on the topic of Uranium- 238. Uranium-238 is the most common isotope of Uranium yielding 99.2 percent wit hin natural uranium. Uranium- 238 has 92 protons and 146 neutrons. It was also recorded that it has a half- life of 4.5 billion years. a. Uranium- 238 is an ionizing radiation. b. Uranium- 238 gives off alpha particles which are not effectively penetrating so s long a its rays are found outside of the b...

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...
