  3. Non-ionizing Radiation 200 Points People use this type of non-ionizing radiation to reheat food.

  4. Non-ionizing Radiation 200 Points What is microwave radiation? Back to question board

  5. Non-ionizing Radiation 400 Points This radiation is used in the operation of cell phones.

  6. Non-ionizing Radiation 400 Points What are radio waves? Back to question board

  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? Back to question board

  9. Non-ionizing Radiation 800 Points Non-ionizing radiation can do this to your skin if you do not wear sunscreen.

  10. Non-ionizing Radiation 800 Points What is give you a sunburn? Back to question board

  11. Non-ionizing Radiation 1000 Points Non-ionizing radiation does not have enough energy to do this.

  12. Non-ionizing Radiation 1000 Points What is ionize atoms or molecules? Back to question board

  13. Ionizing Radiation200 Points X-rays have enough energy to pass through soft tissues of the body, but not these.

  14. Ionizing Radiation200 Points What are bones and metal? Back to question board

  15. Ionizing Radiation400 Points These devices can detect ionizing radiation that our senses cannot see, smell or taste.

  16. Ionizing Radiation400 Points What are Geiger-Müller counters? (Also accept Geiger counters) Back to question board

  17. Ionizing Radiation600 Points These types of rays have large amounts of energy and can ionize atoms in most types of matter.

  18. Ionizing Radiation600 Points What are x-rays and gamma rays? Back to question board

  19. Ionizing Radiation800 Points This may exist in the form of a high-energy photon or charged particle.

  20. Ionizing Radiation800 Points What is ionizing radiation? Back to question board

  21. Ionizing Radiation1000 Points When these interact with the upper atmosphere, they create secondary x-rays and subatomic particles.

  22. Ionizing Radiation1000 Points What are cosmic rays? Back to question board

  24. Sources of Radiation200 Points What is the Sun? Back to question board

  25. Sources of Radiation400 Points This protects us from the ionizing radiation given off by the Sun.

  26. Sources of Radiation400 Points What is the Earth’s atmosphere and magnetic field? Back to question board

  27. Sources of Radiation600 Points Most of the human-made exposure to radiation people receive come from these.

  28. Sources of Radiation600 Points What are medical imaging and treatments? (Also accept medical sources) Back to question board

  29. Sources of Radiation800 Points About 70% of the radiation we are exposed to comes from here.

  30. Sources of Radiation800 Points What is the Earth? Back to question board

  31. Sources of Radiation1000 Points This odourless, colourless gas, which can sometimes be found in mines and basements, is part of the decay chain of uranium-238.

  32. Sources of Radiation1000 Points What is Radon (radon-222)? Back to question board

  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-Life200 Points What is another isotope? Back to question board

  35. Half-Life400 Points The radioisotope uranium-238 has a half-life of this.

  36. Half-Life400 Points What is 4.5 billion years? Back to question board
