title: The dose contribution due to photonuclear reactions during radiotherapy.
abstract: The dose equivalent due to photonuclear reactions within a patient irradiated with 24-MeV bremsstrahlung has been calculated to be about 1% of the photon dose. This is more than two times smaller than the previously accepted estimate.
