When an electron beam is incident upon a stepped surface, such as that which exists when a slab of bolus is present with it's square edge within the portal, the dose distribution is strikingly perturbed. An easily demonstrable explanation is given which utilizes the customary, flat-incident surface electron beam dose distribution
