Types of Radiation | GCSE Physics Practice
Unstable nuclei decay by emitting alpha, beta, or gamma radiation.
Which type of radiation is just an electromagnetic wave?
What is Types of Radiation | Practice?
"Particles or electromagnetic waves emitted from the nucleus of an unstable atom."
Which type of radiation is stopped by a single sheet of paper?
Which type of radiation is an electromagnetic wave?
Why is alpha radiation dangerous inside the body but not outside?
Radiation Properties
Alpha: 2 protons, 2 neutrons. Highly ionising, low penetration.
Beta: Fast electron. Moderately ionising and penetrating.
Gamma: EM wave. Low ionising, high penetration (stopped by lead).
Exam Insight: Use "ionising power" and "penetrating power" as separate keywords in your answers.
