    Hi keweezz,

    A good place to start would be to define the terms. What is a rad? What does RBE mean, and how is it used?

    Yes, a mrad is a milli-rad. But my questions was, what is a rad? Answering that will allow you to get half the problem done.

    I think RBE stands for relative biological effectiveness; but those are just the words. How is the RBE factor used?
