Background: The relative biological effectiveness (RBE) in the modulated proton beams used in different protontherapy facilities has been determined at 1.0–1.4 from in vitro studies (Paganetti, et al. Int J Radiat Oncol Biol Phys. 2002;53:407-21) and estimated at 1.10 (relative to 60Co photons)[for full text, please go to the a.m. URL]
