Question
- A. It is a helium nucleus.
- B. It is a high-speed electron.
- C. It is electromagnetic radiation.
- D. It is a neutron.
Answer
The correct answer is B: It is a high-speed electron..
Explanation
The correct answer is B: It is a high-speed electron.. This supports the learning objective "Identify suitable materials that absorb or reduce alpha, beta and gamma radiation." in Radioactive decay and nuclear radiation because it uses the correct atomic and nuclear radiation relationship for Atoms and nuclear radiation. The other options are less suitable because they do not match the required Radioactive decay and nuclear radiation idea: It is a helium nucleus.; It is electromagnetic radiation.; It is a neutron..
Common mistake
Misunderstanding Radiation Absorption
Students often confuse the materials that can absorb or reduce different types of radiation, thinking that the same material is effective for all types.
To fix this, students should study the specific properties of alpha, beta, and gamma radiation, focusing on which materials are effective for each type. For example, paper can stop alpha particles, while lead is needed for gamma radiation.
