New neutron sources for radiotherapy
Physics in Medicine and Biology, 1984All existing neutron sources suffer from disadvantages which would not be tolerated in modern megavoltage X-ray equipment. Experimental work with 30-60 MeV protons on beryllium and other elements has shown how these difficulties can to a large extent be overcome.

SPIE Proceedings, 2011
Coded aperture techniques have been applied to neutron radiography to address limitations in neutron flux and resolution of neutron detectors in a system labeled coded source imaging (CSI). By coding the neutron source, a magnified imaging system is designed with small spot size aperture holes (10 and 100μm) for improved resolution beyond the ...

Neutron sources for cancer therapy
The British Journal of Radiology, 1980In an investigation of collimated neutron sources suitable for cancer teletherapy, Mijnheer et al. (1978) have reported dose build-up, depth dose, and gamma-ray production for three neutron sources: d(50)+Be, p(42)+Be, and d+T. They conclude that the former two sources are preferable to the d+T source on the basis of the results on depth dose and ...

Neutron spectra of 239PuBe neutron sources
Nuclear Instruments and Methods, 1977Abstract Neutron spectra of 239 PuBe(α, n) sources have been calculated by using the most recent data on the differential cross sections and angular distributions. The contribution from the multibody break-up reaction 9 Be(α, αn) 8 Be has also been incorporated.

A Fast Neutron Source for Radiotherapy
Nature, 1964ONE of the factors which may determine the effectiveness of an X-ray treatment is the oxygen tension in the tumour to be destroyed, in that the radiation is relatively less effective in killing the anoxic cells at the centre. This was demonstrated by Gray et al.1, who also showed that the biological effects produced by 2.3-MeV neutrons are much less ...
