A Fast-neutron Source for Radiotherapy [PDF]

open access: yesNature, 1963
IN a recent note, Lomer and Greene1 have recommended the development of a 14-MeV fast-neutron source for radiotherapy. We feel that there are disadvantages to this approach. The relative biological effectiveness of fast neutrons is related to their linear energy transfer, which in turn varies inversely with the energy of the neutron2,3.

Low energy fusion for a safe and compact neutron source [PDF]

open access: yes, 2013
Neutrons are primarily produced at large international facilities using either spallation reactions or nuclear fission. There is a demand for small scale neutron production for use at hospitals and borders for a variety of applications.

Fast neutron environments. [PDF]

open access: yes, 2011
The goal of this LDRD project is to develop a rapid first-order experimental procedure for the testing of advanced cladding materials that may be considered for generation IV nuclear reactors. In order to investigate this, a technique was developed to expose the coupons of potential materials to high displacement damage at elevated temperatures to ...

Fusion Based Neutron Sources for Security Applications: Neutron Techniques [PDF]

open access: yes, 2014
The current reliance on X-Rays and intelligence for na- tional security is insufficient to combat the current risks of smuggling and terrorism seen on an international level. There are a range of neutron based security techniques which have the potential

Radiological Risks of Neutron Interrogation of Food [PDF]

open access: yes, 2015
In recent years there has been growing interest in the use of neutron scanning techniques for security. Neutron techniques with a range of energy spectra including thermal, white and fast neutrons have been shown to work in different scenarios.

Neutron–Mirror-Neutron Oscillations: How Fast Might They Be? [PDF]

open access: yesPhysical Review Letters, 2006
We discuss the phenomenological implications of the neutron (n) oscillation into the mirror neutron (n'), a hypothetical particle exactly degenerate in mass with the neutron but sterile to normal matter. We show that the present experimental data allow a maximal n-n' oscillation in vacuum with a characteristic time $τ$ much shorter than the neutron ...

Radioisotopes Produced by Neutron Irradiation of Food [PDF]

open access: yes, 2016
The use of neutrons for cargo interrogation has the potential to drastically improve threat detection. Previous research has focussed on the production of 24Na, based on the isotopes produced in pharmaceuticals and medical devices.

Comparison of different geometric configurations and materials for neutron radiography purposes based on a 241Am/Be neutron source

open access: yesJournal of Taibah University for Science, 2017
The present work examines two different geometric configurations and three different lining materials that are suitable for thermal neutron radiography purposes based on a 241Am/Be neutron source.

Evaluation of PWR pressure vessel fast neutron fluence benchmarks from NUREG/CR-6115 with ares transport code [PDF]

open access: yesNuclear Technology and Radiation Protection, 2017
An accurate evaluation of PWR pressure vessel fast neutron fluence is essential to ensure pressure vessel integrity over the design lifetime. The discrete ordinates method is one of the main methods to treat such problems.
