A rаdiаtiоn therаpy student оbserves that range uncertainties оf 3-3.5% seem small, but questions why they're considered a major concern in proton therapy planning. A senior physicist explains this by comparing two scenarios: a 20 cm deep photon beam with 3% uncertainty versus a 20 cm deep proton beam with 3% uncertainty. What is the key difference in clinical impact between the uncertainties of these 2 scenarios?
