Question

Why is gamma radiation considered weakly ionising but highly penetrating compared to alpha and beta radiation?

Answer

Gamma radiation is weakly ionising because it has a low probability of interacting with matter, allowing it to pass through materials easily. However, it is highly penetrating due to its high energy and electromagnetic nature, which enables it to travel through thick barriers.

Explanation

This question assesses the student's ability to compare different types of radiation based on their ionising power and penetration capabilities, highlighting the unique properties of gamma radiation.

Common mistake

Gamma Emission Misunderstanding

Students often think that gamma emission changes the mass number or atomic number of an atom.

Remember that gamma emission is a form of electromagnetic radiation that does not affect the mass number or atomic number; it only releases energy.
