Effects 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...
متن کاملMSGC test with fast neutrons
Results are presented from the exposure of a CMS performance prototype MSGC to a fast neutron beam having an average energy of 20 MeV and an intensity of 7 106 neutrons/mm2/s. A fluence equivalent to 3 years of LHC operation has been accumulated without damages to the detector. The stability of the MSGC operation in a heavily ionising particle flux is reported and the estimation of their produc...
متن کاملEffects of fast neutrons on the eye. A preliminary communication.
Patients with advanced tumours of the head and neck have been treated with fast neutrons from the Medical Research Council's cyclotron at Hammersmith Hospital for the last 5 years. In 62 per cent of the first hundred cases there was complete regression of the tumour and in only two cases did the tumour recur (Catterall and Vonberg, 1974). The effects of these 7-5 MeV neutrons on the normal tiss...
متن کاملOn the scattering of fast neutrons by protons.
1. Introduction. Recent experiments by Amaldi arid his collaborators on the scattering of high-energy neutrons (of 10—15MeV.) by protons (2) have disclosed a considerable anisotropy in the angular distribution of the scattered particles. Theoretical discussions of this problem show an interesting feature in that the results depend sensitively on the basic assumptions involved with regard to the...
متن کاملFast neutrons and misonidazole for malignant astrocytomas.
Twenty-five patients with biopsy proven malignant supratentorial astrocytomas were entered into a Phase I/II study of misonidazole combined with neutron radiation at Fermilab Neutron Therapy Facility (NTF) between August 1979 and April 1981. The main objectives were to determine tissue tolerance in terms of acute and late effects, and to estimate tumor clearance and survival rates. The total do...
