Understanding Radioactivity and Radiation

What is a common misconception about radiation when turning on a light?

• It emits radio waves.

• It releases radioactivity.

• It generates microwaves.

• It produces sound waves.

How is radiation generally defined?

• Energy absorbed by a single point of matter.

• Energy that is visible to the human eye.

• Energy emitted from a single point of matter.

• Energy that is always harmful.

What distinguishes radioactive radiation from non-radioactive radiation?

• Radioactive radiation involves the breakdown of an atom's nucleus.

• Radioactive radiation is always visible.

• Non-radioactive radiation is always harmful.

• Non-radioactive radiation involves the breakdown of an atom's nucleus.

What are the components of particle radiation?

• Protons, neutrons, and electrons.

• Photons and sound waves.

• Microwaves and radio waves.

• Infrared and ultraviolet rays.

Which type of electromagnetic radiation is associated with radioactive decay?

• Visible light and sound waves.

• Infrared and ultraviolet rays.

• X-rays and gamma rays.

• Radio waves and microwaves.

What is a key characteristic of ionizing radiation?

• It can change the number of protons in an atom.

• It can change the color of an atom.

• It can change the number of electrons around an atom.

• It can change the number of neutrons in an atom.

What is the primary effect of non-ionizing radiation on atoms?

• It causes atoms to break apart.

• It causes atoms to emit sound.

• It causes atoms to heat up and move faster.

• It causes atoms to change color.

What can happen to human cells when exposed to ionizing radiation?

• Cells can multiply rapidly.

• Cells can become stronger.

• Cells can die or change.

• Cells can become immune to radiation.

What is a potential health risk associated with ionizing radiation?

• Cancer.

• Improved metabolism.

• Enhanced vision.

• Increased immunity.

How does ionizing radiation affect DNA?

• It makes DNA more resistant to damage.

• It can cause changes that are copied during cell reproduction.

• It strengthens DNA bonds.

• It has no effect on DNA.
