Which radiation is the most ionising?
Answer and explanation
Correct answer: C. Alpha particles
Alpha particles are heavy and strongly charged, so they ionise the most but are stopped by paper.
Answer: Alpha particles.
Why not the others: Beta particles: they ionise less than alpha particles. Gamma rays: they are the least ionising. X-rays: they ionise much less than alpha particles.
