The document explains nuclear radiation, describing it as energy waves emitted from radioisotopes and the significance of isotopes in various applications, including cancer treatment and energy production. It outlines the functioning of nuclear power plants compared to coal-burning plants, highlighting the benefits of nuclear energy despite potential risks and disasters like Chernobyl and Fukushima. Additionally, it discusses the types of radiation and their effects on health, concluding with a note on how to protect oneself from radiation exposure.

1. Nuclear RadiationAnd You!

2. What is radiation?

3. The emission of energy waves through space

4. Nuclear radiation comes from radioisotopes

5. An iso-what?An Isotope

6. Isotope:An atom w/ extra neutrons

7. Review

8. Normal atoms:Equal # of Protons and Neutrons

9. Why do we care?This can happen:

10. Extra neutrons = extra massNormal #Many NeutronsGreater Mass

11. Extra mass means charged particles act differently

12. Masses:1 neutron = 1 proton+1 neutron = +1 atomic mass (but no change in charge)

13. Heavy WaterNormal WaterFrozen Heavy Water

14. Don’t: DRINK!Do: Use to slow down/direct nuclear reactions

15. What radioisotopes do we use?UraniumCesiumIodine

16. Wait, don’t they glow?

17. Sorry to burst your bubble!Nope, that’s science fiction stuff

18. Well, ok, but what are isotopes used for?!?

19. CatalystsUsed to make chemical reactions occur faster

20. Following pathways in your body

21. DNA and radiation don’t play nice

22. CancerTreatments

23. Cancer’s DNA is damaged

24. Radiations pushes the cancer cell over the edge

25. Radiation can damage DNA…until the cell dies

26. Some things in science should be left aloneWarfare

27. We can use it for energy!!!

28. Why?Very little waste is produced!

29. Coal burning creates heat to boil H2O

30. The H2O steam travels down a pipeCreating lots of pressure!!!

31. The steam blasts against a turbineThus turning it

32. A magnet turns inside a copper coilMaking electrons flow

33. Flowing e-= ELECTRICITY

34. Shocking, isn’t it?

35. Electricity powers our

36. Pro:Coal is CHEAP!

37. Con:Burnt coal gives up many pollutants

38. Greenhouse GasesGlobal Warming = Not Cool

39. So, what is ‘clean energy?’

40. Nuclear isotopes give off thermal E

41. What can this heat be used for?!?

42. Boil H2O, of course!

43. The process continues like coal-burning plantsBut no pollution

44. There are many safety regulationsBut accidents do happen

45. Chernobyl, Ukrainian SSR

46. ~4,000 died, many suffered

47. Three Mile Island, U.S.A.

48. Fukushima Daiichi, Japan

49. What happened in Japan?

50. JapanHit by 8.9 M earthquake, followed by scores of tremorsCausing a massive tsunamiEarthquake damages nuclear reactor and radiation shieldsMeltdown commencing

51. What’s a meltdown?Melting of nuclear fuel rods

52. If the rods cannot be cooled?Then they release too much heatThen melt and combust

53. Drop in sea H2O to cool the fuel(as a last resort)

54. Combustion creates gassesNO!! Not that kind!

55. Gasses that rise when heatedCombustion also causes heatRadioactive particles get caught in the escaping gas and travel 1000s of miles by wind

57. Gases Contain Radioactive Subs.The Radioisotopes breakdown

58. These Isotopes release:Alpha particle – a, 2p2n, He-2e-Beta particle – β, high-speed e- or positronPositron – antimatter electron counterpartGamma particle – γ, lowest form of radiation on the EM Scale, mainly produced by fission (atom-fission nuclear explosive)

59. Radiation PoisoningHeadache/FeverNauseaDeathItching/BlisteringVomiting

60. The Particles can TravelAround the World

61. How can you protect yourself?

62. …Next TimeYa’ll come back, now, ya here?
