متن کاملEnhancement of Nucleosynthesis Reaction Rates Due to Nonthermalized Fast Neutrons
It is usually assumed in stellar nucleosynthesis calculations that neutrons art completely thcrmalizcd. Hence, if the cross section of a neutron-induced reaction has a threshold, or it is suppressed by the Coulomb barrier in the exit channel, the reaction rate is quite low. However, the contribution front the decelerating fast neutrons has been neglected previously. We show that, though ihe fra...
متن کاملDose equivalent from 500 MeV neutrons
Neutrons constitute a major component in the radiation fi eld outside the shielding of particle accelerators. Consequently appropriate neutron dose meters are needed to survey the radiation levels. A thermo-luminescence based neutron dosemeter is used at the UNILAC as well as at the SIS. It has been modifi ed to improve the response for high energetic neutrons (extended range). We report on a t...
متن کاملEnergy Spectrum of Fast Neutrons Produced by 130 MeV Protons in Water
In proton radiation therapy nuclear reactions of highenergy protons hitting beam line components (e.g. collimators or other beam shaping devices) lead to the production of secondary neutrons which may result in significant neutron dose equivalent values (typically of the order of mSv per treatment Gy), depending on the treatment techniques [1]. For scanning devices the neutron dose contribution...
متن کاملEffects of fast neutrons on the eye.
The study of 93 eyes receiving neutron irradiation establishes the character of the ophthalmic complications of neutron. Significant changes are produced in the eyelids, conjunctiva, and cornea, but the production of cataract is relatively unimportant. No reaction was seen after neutron treatment that had not already been seen after chi or gamma radiation. That the unavoidable damage is similar...
