Question
Explain why an irradiated object does not become radioactive.
Answer
An irradiated object does not become radioactive because irradiation involves exposure to ionising radiation from a radioactive source, which does not change the atomic structure of the object. The radiation may pass through the object or interact with it temporarily, but it does not result in the object itself emitting radiation.
Explanation
This answer demonstrates an understanding of the distinction between irradiation and radioactive contamination. It tests the student's ability to explain the process of irradiation and its effects on materials, aligning with the learning objective.
Common mistake
Confusing Irradiation with Contamination
Students often think that an irradiated object becomes radioactive.
Remember that irradiation is just exposure to radiation; it does not change the object's atomic structure.
