- B.When radioactive materials are improperly handled

Model answer
What a good answer should say
- When radioactive materials are improperly handled
Explanation
Why this works
Contamination is most likely to occur when radioactive materials are not handled correctly, leading to their presence on surfaces or within living organisms. This can happen in laboratories, during transportation, or in waste disposal scenarios.
In contrast, irradiation can occur in controlled settings, such as medical treatments or industrial applications, where exposure is managed. Thus, contamination is linked to improper handling, while irradiation is often a deliberate exposure.
