Nuclear Science

  1. 2. <ul><li>WHAT IS NUCLEAR WASTE? </li></ul>
  2. 3. <ul><li>Nuclear waste: is the remains of radioactive decay, or nuclear fission. </li></ul>
  3. 4. <ul><li>HOW IS IT MADE? </li></ul>
  4. 5. <ul><li>Nuclear waste is made mostly by radioactive decay. </li></ul>
  5. 6. <ul><li>What is radioactive decay? </li></ul>
  6. 7. <ul><li>Its the process in which radioactive isotopes release gamma rays and lose particles. </li></ul>
  7. 8. <ul><li>There are 3 types of radio active decay:alpha, Beta, and gamma. </li></ul>
  8. 12. <ul><li>Can Nuclear waste affect our health? </li></ul>
  9. 13. <ul><li>Yes, in a number of ways. One of the largest dangers is that radioactivity is a carcinogen. </li></ul>
  10. 14. <ul><li>A carcinogen is a substance that causes cancer. </li></ul>
  11. 15. <ul><li>It also affects our DNA. </li></ul>
  12. 16. <ul><li>How does it affect our DNA? </li></ul>
  13. 17. <ul><li>It affects our DNA in 2 main ways: </li></ul>
  14. 18. <ul><li>1. Isotopes push an electron out of its orbit, if this electron strikes the DNA, it damages it. </li></ul>
  15. 19. <ul><li>2. if this electron collides with a water molecule, it becomes an isotope, damaging your DNA. </li></ul>
  16. 20. <ul><li>All this takes less than 1 second. </li></ul>
  17. 21. <ul><li>Radioactivity relesed from nuclear waste can also damage body cells. </li></ul>
  18. 22. <ul><li>HOW? </li></ul>
  19. 23. <ul><li>The electrons can ionize the cell, making it “decay” </li></ul><ul><li>Or it can stop the cell from reproducing. </li></ul>
  20. 24. <ul><li>But then how do scientists that handle nuclear waste survive? </li></ul>
  21. 25. <ul><li>They wear special suits, that reflect gamma radiation. </li></ul>
  22. 26. Like this
  23. 27. SO DON’T DO THIS:
  24. 28. LEAVE IT TO THESE GUYS:
  25. 29. Otherwise its….
