  3. Nuclear Reactors200 Points At the heart of nuclear reactors are these (which are no bigger than the tip of your finger).

  4. Nuclear Reactors 200 Points What are fuel pellets?

  5. Nuclear Reactors 400 Points A single nuclear fuel pellet can power an average home for this many weeks.

  6. Nuclear Reactors 400 Points What is 6 weeks?

  7. Nuclear Reactors 600 Points CANDU nuclear fuel pellets are made from this.

  8. Nuclear Reactors 600 Points What is naturally occurring uranium? (Mined in Canada)

  9. Nuclear Reactors 800 Points This is necessary to absorb and remove heat produced by nuclear fission in a reactor.

  10. Nuclear Reactors 800 Points What is a coolant?

  11. Nuclear Reactors 1000 Points These can be introduced into a reactor to stop the fission process when required and to control the level of power during operations.

  12. Nuclear Reactors 1000 Points What are control rods?

  13. Nuclear Medicine 200 Points Nuclear medicine began to be developed in the 1950s by doctors who were focused on treating this.

  14. Nuclear Medicine 200 Points What is thyroid disease?

  15. Nuclear Medicine 400 Points Cobalt-60 is used to sterilize more than 45% of the world’s supply of these.

  16. Nuclear Medicine 400 Points What are single-use medical supplies?

  17. Nuclear Medicine 600 Points 60 000 of these are used in medical procedures each day.

  18. Nuclear Medicine 600 Points What are Canadian-produced medical isotopes?

  19. Nuclear Medicine 800 Points This isotope is used in four out of five nuclear medicine procedures.

  20. Nuclear Medicine 800 Points What is molybdenum-99?

  21. Nuclear Medicine 1000 Points In this year, the first two cancer treatment machines using cobalt-60 were produced in Canada.

  22. Nuclear Medicine 1000 Points What is 1951?

  23. Cobalt-60 Therapy Unit 200 Points Before the cobalt-60 therapy unit, ionizing radiation from these were used to treat cancers.

  24. Cobalt-60 Therapy Unit 200 Points What are radium and x-rays?

  25. Cobalt-60 Therapy Unit 400 Points These are produced during the beta decay of cobalt-60.

  26. Cobalt-60 Therapy Unit 400 Points What are gamma rays?

  27. Cobalt-60 Therapy Unit 600 Points In the cobalt-60 therapy unit, these shape the beam of gamma rays as it is directed at the patient.

  28. Cobalt-60 Therapy Unit 600 Points What are a series of collimators and jaws?

  29. Cobalt-60 Therapy Unit 800 Points In North America, many cobalt-60 therapy units have been replaced with this newer technology.

  30. Cobalt-60 Therapy Unit 800 Points What is Intensity-Modulated Radiation Therapy (IMRT)?

  31. Cobalt-60 Therapy Unit 1000 Points On October 27, 1951, the first cobalt-60 treatment occurred here.

  32. Cobalt-60 Therapy Unit 1000 Points What is Victoria Hospital in London, Ontario?

  33. Commercial Applications 200 Points Radiography using a radioactive source is used to inspect finished goods for this.

  34. Commercial Applications 200 Points What are weaknesses and flaws?

  35. Commercial Applications 400 Points Photocopiers use small amounts of radioactive material to do this.

  36. Commercial Applications 400 Points What is eliminate static and prevent paper from sticking together?

  37. Commercial Applications 600 Points In 1992, the World Health Organization called this a “perfectly sound food preservation technology.”

  38. Commercial Applications 600 Points What is food irradiation?

  39. Commercial Applications 800 Points This is the radioactive metal usually used in smoke detectors.

  40. Commercial Applications 800 Points What is americum-241?

  41. Commercial Applications 1000 Points CANDESAL Water Systems, a Canadian company, was formed to develop this concept.

  42. Commercial Applications 1000 Points What is nuclear desalination combining CANDU reactors with DESALination?

  43. Space & Aeronautical Applications 200 Points In 1961, the first of these used in a space mission was launched aboard a US Navy navigation satellite.

  44. Space & Aeronautical Applications 200 Points What is radioisotope thermo-electric generator (RTG) ?

  45. Space & Aeronautical Applications 400 Points Radioisotope thermo-electric generators (RTGs) convert the heat generated by this into electricity.

  46. Space & Aeronautical Applications 400 Points What is the decay of plutonium-238?

  47. Space & Aeronautical Applications 600 Points To date, NASA has launched over this many missions equipped with RTGs.

  48. Space & Aeronautical Applications 600 Points What is 25?

  49. Space & Aeronautical Applications 800 Points The New Horizons probe, which uses RTG technology, is on the way to look at this object in space.

  50. Space & Aeronautical Applications 800 Points What is Pluto?
