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 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 کاملThe Effect of Fast Neutrons on Chromosomes in Meiosis and Its Bearing upon Pachytene Pairing.
REVIOUS experiments have shown that quantitatively the response P of chromosomes of Vicia faba in pachytene to X-rays is approximately the same as that of the same species at the onset of the somatic prophase (MARSHAK 1939a). CREIGHTON (1941) using methods similar to those employed in the Vicia studies found that meiotic chromosomes are only a sixth as sensitive as the mitotic chromosomes in Ch...
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 thermal neutrons on living cells. II. Combined effects of thermal neutrons and several agents which interact with DNA.
牧 広利,河 合建一,赤 星光彦:京 都大学原子炉実験所,大 阪府泉南郡熊取町野田,〒590-04 In order to understand the further mechanisms of lethal actions of thermal neutrons, the combined effects of thermal neutrons and several chemical agents which interact with DNA, mainly bleomycin and actinomycin D, have been studied. Marked sensitization was observed with bleomycin even in its lower concentration, while in the case of actinomyci...
