Thermal Transport in Thorium Dioxide [PDF]
Volume 6: Energy, 2017 Thorium is more abundant in nature than uranium and thorium fuels can breed fissile U-233 fuel that can be used in various types of nuclear reactors. Moreover, thorium dioxide has drawn interest from researchers due to its relatively superior thermal properties when compared to conventional uranium dioxide fuel pellets. In this study, thermal transport

Meningioma Induced by Thorium Dioxide
New England Journal of Medicine, 1963THORIUM dioxide (Thorotrast) was introduced as a contrast medium for cerebral angiography by Egas Moniz et al.1 in 1931. Its instillation into the subarachnoid space and ventricles for encephalomyelography was described in the following year by Radovici and Meller.2 , 3 This contrast medium, containing thorium, with a half-life of 1.4 X 1010 years, was

Treatment of Thorium Dioxide Granulomas of the Neck
New England Journal of Medicine, 1963COLLOIDAL thorium dioxide in dextran (Thorotrast) was formerly used as a radiographce contrast medium in a variety of diagnostic procedures. The compound contained radioactive thorium, a potent alpha emitter with a long half-life (1.4 X 1010 years). Intravascular, intracavitary and interstitial instillations, which were either retained by the reticul ...

Modeling of thorium (IV) ions adsorption onto a novel adsorbent material silicon dioxide nano-balls using response surface methodology [PDF]
Applied Radiation and Isotopes, 2016 The silicon dioxide nano-balls (nano-SiO2) were prepared for the adsorption of thorium (IV) ions from aqueous solution. The synthesized silicon dioxide nano-balls were characterized by Scanning Electron Microscopy/Energy Dispersive X-ray, X-ray ...

Vascular complications of thorium dioxide
The American Journal of Medicine, 1978Vascular complications occurring late after exposure to thorium dioxide (thorotrast) are described in two patients. One patient had both cerebral andmyocardial infarcts and died at age 25 years. Necropsy disclosed both adventitial and intimal fibrosis of the left carotid artery and greater than 75 per cent cross-sectional area luminal narrowing of both

Thorium dioxide (Thorotrast), a radioactive substance with a very long half-life, has been used in the past as a contrast medium for various roentgenologic studies. Some of these have been followed by the delayed appearance of benign and malignant tumors, especially of the liver.
