Uranium Radiation Properties

Uranium Radiation Properties

Uranium. Uranium is a metal of high density 18.9 gcm 3.The earths crust contains an average of about 3 ppm 3 gt uranium, and seawater approximately 3 ppb 3 mgt. Naturally occuring uranium consists of three isotopes U-238 more than 99, U-235, and U-234, all of which are radioactive and have very long half-lives, i.e. decay very slowly.

The Precipitation of Uranium With Hydrogen Peroxide

The Precipitation of Uranium With Hydrogen Peroxide

The direct precipitation of uranium with hydrogen peroxide has been known since 1877. Commercial use of the process began in the 1960s. During 1967 the US Bureau of Mines USBM assisted the Climax Uranium Co., Grand Junction, CO in the development of a uranyl peroxide precipitation process to control a molybdenum impurity problem Shabbir and Tame, 1978.
