2. Where do radioactive substance give out radiation from? Is it random or regulated?

  • From the nucleus, it's a regulated process
  • From the protons, it's a random process
  • From the nucleus, it's a random process
  • From electrons, it's a random process

3. What types of radiation are there?

  • Gamma, Beta, Delta,
  • Alpha, Beta, Gamma
  • Alpha, Gamma, Delta
  • Alpha, Beta, Delta

4. What type of particles are alpha particles? (hint, it's an element)

  • Hydrogen nuclei, 1 proton, 1 neutron
  • Helium nuclei. 2 protons, 2 neutrons
  • Nitrogen nuclei. 6 protons, 6 neutrons
  • Oxygen nuclei. 4 protons, 2 neutrons

5. Which particle is the slowest, and is the most ionising?

  • Alpha is big and slow movin', it doesn't penetrate very far into materials. It is strongly ionising, (creates lots of ions). Beta particles move fast and they're small. Gamma particles penetrate far into materials, and are weakly ioonising.
  • Beta particles are the slowest, and are the most ionising, they're small too.
  • Gamma particles penetrate far into materials, and are the slowest. They're the most ionising.
  • Alpha particles are the fastest and smallest, and the least ionising.
