Peripheral photon and neutron doses from prostate cancer external beam irradiation

Peripheral photon and neutron doses from external beam radiotherapy (EBRT) are associatedwith increased riskof carcinogen-esis in the out-of-field organs; thus, dose estimations of secondary radiation are imperative. Peripheral photon and neutron dosesfrom EBRTof prostate carcinomawere measured in Randophantom.
