Questions and Answers

What is the definition of Relative Biological Effectiveness (RBE)?

  • The absorbed doses lead to the same biological endpoint. (correct)
  • The absorbed doses from different types of radiation have different biological effects.
  • The absorbed doses from different types of radiation show the same biological damages.
  • The absorbed doses lead to different biological endpoints.

What factor affects or determines Relative Biological Effectiveness (RBE)?

  • Dose rate in joules
  • Biological system or endpoint (correct)
  • Number of radiation sources
  • Radiation wavelength

How does Relative Biological Effectiveness (RBE) change with different endpoints?

  • RBE increases with different endpoints (correct)
  • RBE decreases with different endpoints
  • RBE is not affected by endpoints
  • RBE remains constant regardless of endpoints
