Model answer
What a good answer should say
- Contamination involves radioactive material; irradiation does not
Explanation
Why this works
The key difference is that contamination refers to the presence of radioactive material on surfaces or within organisms, while irradiation refers to the exposure to radiation from a radioactive source without the material being present. Contamination can lead to internal exposure and health risks, while irradiation is often controlled and used in medical or industrial applications.
Understanding this distinction is crucial for implementing safety measures in environments where radiation is present.
