Pulmonary sequelae after electron spinal irradiation
Radiotherapy and Oncology, 2001We measured pulmonary function in 21 patients, after craniospinal irradiation with a posterior spinal electron beam. The median age at treatment was 7.5 years. Nine patients (43%) demonstrated abnormal pulmonary function tests, five with restrictive changes, one with isolated diminished diffusion capacity, and three with obstructive disease.

Gamma and electron irradiation
Physics Bulletin, 1969The UK Panel on Gamma and Electron Irradiation was set up in 1963 by the coming together of industrial organizations, the UK Atomic Energy Authority, the Ministry of Health and interested individuals mainly from the universities. Originally its purposes were connected with the promotion of fundamental and applied research into the use of radiation for ...

Electron beam irradiation of dental composites
Dental Materials, 2005Electron beam irradiation can be used to influence the mechanical properties of polymers. It was the aim of this study to investigate whether dental composites can benefit from irradiation in order to achieve increased fracture toughness, work of fracture, hardness or less wear.Two hundred rectangular specimens of five veneering composites were ...

Effects of Electronic Irradiation on Fats
Nature, 1952IRRADIATION with high-velocity electrons has recently been shown to produce changes, apparently of an oxidative nature, in the fatty components of foods1–3, and further investigation of the phenomenon with butter-fat has revealed a number of interesting features. In the experiments we describe, samples 2–3 mm. thick were irradiated in the electron beam

Electron paramagnetic resonance of electron-irradiated GaP
Physical Review B, 1981An electron paramagnetic resonance (EPR) study of electron-irradiated GaP is presented with emphasis on the properties of the isolated gallium vacancy which can be deduced from its EPR. Further confirmation of the assignment of this spectrum to the vacancy is presented with additional discussion of defect structure. Details of the optical excitation of

Electron trapping in electron-beam irradiated SiO2
Journal of Applied Physics, 1978In addition to the well-known positive space charge, electron irradiation of MOS capacitors with 25-keV electrons is shown to introduce additional uncharged electron traps into the oxide layer. These traps persist after most of the positively charged defects have been removed by the usual low-temperature (? °C) anneals. Their presence after this anneal

Megavolt electron irradiation for localized mycosis fungoides
International Journal of Radiation Oncology*Biology*Physics, 1979A retrospective analysis was carried out to evaluate the effectiveness of small field megavolt electron irradiation for localized mycosis fungoides. Only local field electron beam therapy was employed for limited disease reserving total skin electron irradiation for multiple lesions or diffuse disease covering at least 25 per cent of the entire body ...

Cooperative Transport Effects in Electron-Irradiated Glasses
Physical Review Letters, 1985Cooperative effects during both alkali-Ca and Na-K migration under electron irradiation of glasses have been pointed out for the first time by analysis of experimental data in the framework of the thermodynamics of irreversible processes.

Electron spin resonance in electron-irradiated diamond
Philosophical Magazine, 1962Abstract The room temperature electron spin resonance spectrum of type IIa diamonds irradiated with 2 Mev electrons has been measured at a frequency of 9.5 kMc/s. The spectrum has been analysed into four systems, all of which show a g value within 0.2% of the free-spin value: A single isotropic line with a width of about 5 gauss.

Electron irradiation damage in magnesium
Acta Metallurgica, 1977Abstract In this paper the results of electron irradiation in thin foils of magnesium in a high voltage electron microscope are described. Elongated, non-basal perfect loops with Burgers vectors a 3 〈1120〉 are formed at room temperature. The loops are interstitial in nature.
