2015 Med Phys I Lecture 3.3a PreTest Question Title * 1. Name: Question Title * 2. A thermal neutron interacts with soft tissue. The most likely outcome of this interaction is Elastic Scatter Inelastic Scatter Nuclear Fission Neutron Activation Question Title * 3. Consider the reaction 197Au+n → 198Au+γ. Is this reaction an example of: Scatter Absorption Non-elastic process Question Title * 4. What type of neutron interaction is more likely to occur at high energies in high-Z materials and changes the number of nucleons in the target nucleus? Elastic scatter Inelastic scatter Non-elastic scatter Absorption Question Title * 5. According to the compound nucleus model, the energy of the outgoing particle is determined by which of the following? the incoming energy of the colliding particle both the properties of the incoming particle and the state of the excited compound nucleus the properties of the excited target nucleus Question Title * 6. To slow down low-energy neutrons effectively, which interaction would you use? Inelastic scattering Elastic scattering with O-16 Non-elastic scattering Elastic scattering with H-1 Question Title * 7. Are there any issues that are not clear to you at this time? Done
