What is contamination in the context of radiation safety?.

- B.Exposure to radiation from a radioactive source
- C.The process of shielding against radiation
- D.The measurement of radiation levels in an area
Model answer
What a good answer should say
- The presence of radioactive material on surfaces or in the body
Explanation
Why this works
Contamination refers to the unwanted presence of radioactive substances on surfaces or within living organisms, which can lead to internal exposure. This differs from irradiation, which involves exposure to radiation without the radioactive material being present.
Contamination applies when radioactive materials are improperly handled or disposed of, while irradiation occurs during medical treatments or industrial applications. Therefore, contamination is specifically about the material itself, while irradiation focuses on the exposure to radiation.
