Nuclear Test Review
- How many protons do N-14 and C-14 have?
- Eventually C-14 will decay back into N-14 through what process?
- What happens to your levels of C-12 after you die?
- What happens to your levels of C-14 after you die?
- What types of materials cannot be dated with C-14 techniques.
- What % of C-14 remains in a carbon-bearing material after 4 half-lives of time have gone by
- How many half-lives of time have passed when only a little more than 12% of a sample of original U-238 still remains?
- What happens in alpha decay, and how much can it penetrate?
- What happens in beta decay, and how much can it penetrate?
- What happens in gamma decay, and how much can it penetrate?
- What happens to U-238 when it goes through alpha decay
- If you see Thorium written as Th*, the * means what?
- Explain what nuclear fusion is.
- What is nuclear fission?
- Nuclear power plants use what process to get their energy
- In what year was the first nuclear weapon used and by who?
- When scientists cause an element to change into another element this is called?
- Elements with the same number of protons but differing number of neutrons are known as what?
- What is the approximate age, in years, of a sample that contains about 6 % of its original C-14? (1/2 life= 5700 yrs)
- What is the name of the force that holds the nucleus together?
- What is the most common isotope of Uranium
- What is a geiger counter?
- What does the atomic number tell you?
- What are the protons and neutrons added together?
- U-235 and U-238 are both used in nuclear power plants. Which is more “dangerous.” We are concerned about Iran getting too much concentrated amounts of this one.
