1. Which of the following best describes the nature of alpha radiation?
- A. A helium nucleus consisting of two protons and two neutrons
- B. A high-energy electromagnetic wave with no mass
- C. An electron emitted from the nucleus
- D. A neutron released during nuclear decay
2. When comparing the penetrating ability of the three types of nuclear emission, which statement is correct?
- A. Gamma radiation is stopped by paper, beta by aluminium, alpha by lead
- B. Alpha particles penetrate furthest through matter
- C. Gamma radiation penetrates furthest, then beta, then alpha particles
- D. All three have equal penetrating ability but different ionising effects
3. Alpha particles have a higher ionising effect than beta particles. Which explanation accounts for this?
- A. Alpha particles travel faster than beta particles
- B. Alpha particles have a larger electric charge and interact more strongly with electrons in atoms they pass through
- C. Gamma radiation interferes with alpha particles, reducing beta ionisation
- D. Beta particles are too small to ionise matter effectively
4. How would alpha and beta particles behave differently when passing through an electric field?
- A. Both would deflect in the same direction towards the positive plate
- B. Alpha particles would deflect towards the negative plate; beta particles towards the positive plate
- C. Neither would deflect because they are too massive
- D. Only beta particles would deflect; alpha particles are unaffected by electric fields
5. A nucleus emits radiation spontaneously. Which of the following statements about this process is correct according to the specification?
- A. The nucleus will always emit the same type of radiation each time
- B. The emission occurs in a specific direction determined by the orientation of the nucleus
- C. The emission is random in direction and cannot be predicted for individual nuclei, though patterns emerge statistically
- D. External factors such as temperature can be used to control which nuclei decay and when
