Question
- A. Exposure to ionising radiation
- B. The unwanted presence of radioactive atoms on or inside an object
- C. The process of radioactive decay
- D. The emission of radiation from a nucleus
Answer
The correct answer is B: The unwanted presence of radioactive atoms on or inside an object.
Explanation
The correct answer is B: The unwanted presence of radioactive atoms on or inside an object. This supports the learning objective "Compare the hazards of alpha, beta and gamma radiation inside the body." in Radioactive contamination 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 contamination idea: Exposure to ionising radiation; The process of radioactive decay; The emission of radiation from a nucleus.
Common mistake
Misunderstanding Radiation Hazards
Students often confuse the hazards of alpha, beta, and gamma radiation when considering their effects inside the body, thinking all types pose the same level of risk.
To fix this, students should study the properties of each type of radiation, focusing on their ionising power and penetration abilities, and understand that alpha particles are more harmful when ingested due to their strong ionising capability.
