    The entrance dose for the 6 mv photon beam is too high- this question might lead to some confusion on PDD curves if not looked at carefully. Most people will be looking for around 17% entrance dose for 6 MV

      Thanks! TBH, I’d be impressed with anyone that notices a poorly measured entrance dose but misses that it’s a photon beam haha.

    For the electron PDD curve, D90 is shown twice as a function of the percent maximum (Y – axis). I believe that was meant to be shown as D80 which corresponds to the depth of R80 (X -axis).
