Question
Explain how ionising radiation can damage cells and DNA.
Answer
Ionising radiation can damage cells and DNA by causing ionization of atoms within the cells. This ionization can lead to breaks in the DNA strands, resulting in mutations or cell death, which may contribute to cancer development.
Explanation
This answer demonstrates an understanding of the biological effects of ionising radiation, specifically its impact on cellular structures and genetic material. It tests the student's ability to connect the concept of ionisation with potential health risks.
Common mistake
Misunderstanding Ionising Radiation Effects
Students often think that ionising radiation only causes immediate damage to cells and DNA, not considering long-term effects.
Emphasize that ionising radiation can lead to mutations and increase cancer risk over time, highlighting both immediate and long-term biological impacts.
