  3. Non-ionizing Radiation200 Points This is a form of energy that can travel through space in the form of a wave or as fast-moving particles.

  4. Non-ionizing Radiation 200 Points What is radiation?

  5. Non-ionizing Radiation 400 Points Non-ionizing radiation does not have enough energy to do this.

  6. Non-ionizing Radiation 400 Points What is ionize atoms or molecules?

  7. Non-ionizing Radiation 600 Points Non-ionizing radiation is found at the low-energy end of this spectrum.

  8. Non-ionizing Radiation 600 Points What is the electromagnetic spectrum?

  9. Non-ionizing Radiation 800 Points Non-ionizing radiation is part of this spectrum.

  10. Non-ionizing Radiation 800 Points What is the electromagnetic spectrum?

  11. Non-ionizing Radiation 1000 Points This radiation is used with cell phones.

  12. Non-ionizing Radiation 1000 Points What are microwaves?

  13. Ionizing Radiation 200 Points This may exist in the form of a high-energy photon or charged particle.

  14. Ionizing Radiation 200 Points What is ionizing radiation?

  15. Ionizing Radiation 400 Points These types of rays have large amounts of energy and can ionize atoms in most types of matter.

  16. Ionizing Radiation 400 Points What are x-rays and gamma rays?

  17. Ionizing Radiation 600 Points These devices can detect ionizing radiation that our senses cannot see, smell or taste.

  18. Ionizing Radiation 600 Points What are Geiger-Müller counters? (will also accept Geiger counters)

  19. Ionizing Radiation 800 Points X-rays have enough energy to pass through soft tissues of the body, but not these.

  20. Ionizing Radiation 800 Points What are bones and metal?

  21. Ionizing Radiation 1000 Points These are the three forms of ionizing radiation that are a result of activity within the nucleus of an atom.

  22. Ionizing Radiation 1000 Points What are alpha particles, beta particles and gamma rays?

  23. Sources of Radiation200 Points This is the largest source of ionizing and non-ionizing radiation in the solar system.

  24. Sources of Radiation 200 Points What is Sun?

  25. Sources of Radiation 400 Points This protects us from the ionizing radiation given off by the Sun.

  26. Sources of Radiation 400 Points What is the Earth’s atmosphere and magnetic field?

  27. Sources of Radiation 600 Points Your body receives about this percentage of its exposure to natural sources of ionizing radiation from the Earth itself.

  28. Sources of Radiation 600 Points What is 70%?

  29. Sources of Radiation 800 Points Most of the human-made exposure to radiation people receive come from these.

  30. Sources of Radiation 800 Points What are medical imaging and treatment? (Will also accept medical sources)

  31. Sources of Radiation 1000 Points Two of these radioisotopes have long half-lives and are found in rocks, soil and water.

  32. Sources of Radiation 1000 Points What are uranium (238), potassium (40), thorium (232), carbon (14)? (accept any two elements)

  33. Half-Life200 Points An isotope’s half-life is the amount of time it takes for half of the atoms of an isotope to decay into this.

  34. Half-Life 200 Points What is another isotope?

  35. Half-Life 400 Points The radioisotope uranium-238 has a half-life of this.

  36. Half-Life 400 Points What is 4.5 billion years?

  37. Half-Life 600 Points The uranium-238 decay series ends with this stable isotope.

  38. Half-Life 600 Points What is lead-206?

  39. Half-Life 800 Points Beta particles are also known as this.

  40. Half-Life 800 Points What are electrons?

  41. Half-Life 1000 Points This would be the amount of bismuth-214 (half-life of 20 minutes) remaining after 1 hour if you started with 1000 g.

  42. Half-Life 1000 Points What is 125 g?

  43. Nuclear Decay200 Points A radioisotope will continue to undergo radioactive decay until this happens.

  44. Nuclear Decay 200 Points What is it becomes stable?

  45. Nuclear Decay 400 Points This type of ionizing radiation is made up of two protons and two neutrons.

  46. Nuclear Decay 400 Points What is an alpha particle?

  47. Nuclear Decay 600 Points An alpha particle is equivalent to the nucleus of this type of atom.

  48. Nuclear Decay 600 Points What is a helium atom?

  49. Nuclear Decay 800 Points Gamma rays are a highly penetrating ionizing electromagnetic radiation in the form of these.

  50. Nuclear Decay 800 Points What are photons?
