    The - in “iso-effect” is probably not a minus sign, but an ordinary hyphen, thus \textrm is the better choice (the same applies for “photon” and “test” as well). I would also move \left. to the left of \frac (it doesn’t change the output but is probably semantically correct). Commented Jan 12, 2013 at 13:56
  • looks to me like the "RBE" should also be \textrm. Commented Jan 12, 2013 at 17:29
  • @barbarabeeton Looking at the provided figure, I think you are right. Edited.
