What different kinds of radiation do when absorbed

Grade 11 Science Worksheet - Challenge Me

Circle the best answer, or write your answer on the line.

  1. RadiologyInfo lists natural background as about 3 mSv a year and a chest X-ray as 0.1 mSv. A year of natural background equals how many chest X-rays, Ari?

  2. RadiologyInfo lists natural background as about 3 mSv a year and a dental X-ray as 0.005 mSv. A year of natural background equals how many dental X-rays, Bo?

  3. A blog post says: “Wi-Fi radio waves knock electrons out of atoms.” Is that supported, Jun?

    • No: radio waves are non-ionizing
    • Yes: Wi-Fi is a kind of X-ray
    • Yes: wireless signals are ionizing

  4. A clinic leaflet says: “A chest X-ray gives about as much radiation as 10 days of natural background.” Is that supported, Kira?

    • No: it equals 10 years of background
    • Yes: RadiologyInfo agrees
    • No: chest X-rays give no radiation

  5. A social post says: “Microwaved soup stays radioactive for hours.” Is that supported, Luz?

    • No: microwaves just warm food
    • Yes: microwaves are ionizing
    • Yes: soup soaks up radiation

  6. Noah says a very bright red lamp gives photons more energy than a dim ultraviolet lamp. Agree or disagree?

    • Disagree: each UV photon carries more energy
    • Agree: brighter light has stronger photons
    • Agree: red light is higher in frequency

  7. Pia says sunscreen works by blocking much of the sun's ultraviolet. Agree or disagree?

    • Disagree: sunscreen blocks visible light
    • Disagree: sunburn comes from infrared
    • Agree: UV causes sunburn

  8. Which band is best suited to warming the water in food quickly, Ren?

    • X-rays
    • Microwaves
    • Radio waves from a broadcast tower

  9. Which band lets a dentist take a picture of teeth inside the jaw, Tala?

    • Radio waves
    • X-rays
    • Infrared

  10. Which band makes the hidden marks on some banknotes glow under a special lamp, Zee?

    • Ultraviolet
    • Gamma rays
    • Microwaves

About this worksheet

What different kinds of radiation do when absorbed. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can find the energy of one photon, E = hf, in eV, and say that it rises with frequency.
  • I can place the ionizing line. The EPA lists radio waves, microwaves and visible light as non-ionizing, and X-rays and gamma rays as ionizing. I can explain that ionizing depends on each photon's energy, not on how bright a beam is.
  • I can describe what absorption does: microwaves and infrared warm (ΔT = Pt ÷ mc), visible light powers plants, and ultraviolet can cause sunburn, which sunscreen helps block.
  • I can compare imaging doses with natural background (a chest X-ray is about 10 days' worth) and check short published-style claims against these facts.

Standard: HS-PS4-4

Words to know

photon: One packet of electromagnetic energy

electron volt (eV): A tiny energy unit for single photons

ionizing: Able to knock electrons out of atoms (EPA)

non-ionizing: Not able to remove electrons; can warm or move molecules

millisievert (mSv): A unit for comparing radiation doses

Common mistakes

Your child divided. A photon's energy is Planck's constant × frequency: E = hf.

Your child left out the water's mass. Temperature rise = energy ÷ (mass × specific heat).

Your child divided the small dose by the large one. To count how many small doses fit in a large one, divide large by small.

Questions parents ask

What is the most common mistake with what different kinds of radiation do when absorbed?

Your child divided. A photon's energy is Planck's constant × frequency: E = hf.
