Questions and Answers

What is the main effect of ionizing radiation on atoms?

  • It adds electrons to the atom.
  • It removes electrons from the atom's orbit. (correct)
  • It enlarges the atom's nucleus.
  • It increases the heat of the atom.

    • Which characteristic defines ionizing radiation?

  • It has enough energy to remove electrons. (correct)
  • It only affects molecules, not atoms.
  • It has low energy that does not affect atoms.
  • It produces only heat and no charged particles.

    • What is the outcome of an atom after it interacts with ionizing radiation?

  • It remains unchanged.
  • It loses all of its mass.
  • It becomes a charged or ionized atom. (correct)
  • It becomes a molecule.

    Study Notes

    Radiation Safety

    • Activities involving radiation require safety standards.
    • These include medical uses, operation of nuclear installations, production, transport, use, and management of radioactive waste.
    • Exposure to radiation must be evaluated and controlled to ensure safety for workers, the public, and the environment.

    Ionizing Radiation

    • Ionizing radiation has enough energy to remove electrons from atoms, causing them to become charged or ionized.
    • It is generated due to energy changes in an electron.
    • X-rays and gamma rays are similar and are emitted when an electron transitions from a higher energy level to a lower energy level, releasing excess energy.
    • Neutron radiation is different and consists of free neutrons, usually emitted during nuclear fission (either spontaneous or induced).
    • Neutrons are indirectly ionizing. They are absorbed into stable atoms, making them unstable and more likely to emit other types of ionizing radiation.
