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,...

Initial Post Instructions The Discussions in this course are set up deepen your understanding of the material as you make real world connections and employ creative thinking. To get the most from the se discussions, full engagement is expected on the part of the student. Be sure to stop by the discussion section frequently, not only to post, but to read the postings of your peers and instructor. Engaging with your peers and learning together is key to this experience. For your initial post, choo...

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...
