The Spectral gamma ray data includes uranium, thorium and potassium that logged from 5447 ft. to 5653 ft. depth of the well. The analysis includes values of uranium (U) and thorium (Th) in ppm, where potassium (K) is recorded in percentage. The values of potassium and thorium are plotted on (clay type diagram of Schlumberger).

ABSTRACT The origins and near-surface distributions of the ~250 known uranium and/or thorium minerals
compositions of uranium and thorium in aluminum, varying from 13 weight per cent uranium at zero weight per cent thorium to zero weight per cent uranium at 25 weight per cent thorium, that can be maintained in a one-phase liquid solution at temperatures even lower than 640°C. If a temperature of 650°C. is the minimum,
Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent (234 U) and daughter (230 Th) products of decay, through the emission of an alpha particle.The decay of Uranium 234 to Thorium 230 is part of the much longer decay series begining in 238 U and ending in 206 Pb. For Uranium-Thorium dating, the initial ratio of 230 Th/ 234 U at the time of sample formation ...
University Policy: Uranium and Thorium compound . Applies to users of grams to a few hundred grams of Uranium and thorium compounds (Acetate and nitrate) Lab PI and User Roles and Responsibilities : 1. Training: EHS lab safety training (from EEM website) and Uranium user training (from Radiation Safety website) 2.
Thorium has properties like uranium which allows it to fuel a nuclear chain reaction. But unlike uranium which splits and releases energy, thorium goes through a series of nuclear reactions when exposed to neutrons until it emerges as an isotope of uranium called U-233.
Do not dispose of any uranium or thorium compounds as regular trash or as hazardous chemical waste. In general, all uranium and thorium wastes, regardless of how the uranium or thorium was purchased, must be disposed of as radioactive waste. Contact the Radiation Safety Officer to discuss disposal options and to make disposal arrangements.
The RSO must include your uranium and thorium materials in the overall University inventory and will work with you to determine disposal needs. Additionally, the RSO may arrange for EHS to conduct quarterly contamination surveys in your lab space. Training. If you plan to work with uranium or thorium compounds, complete the online Radiation ...

9 1.5.2 Uranium-233-Thorium Fuel Cycle Startingin the 1950s, there was major interest in developing a fuel cycle based on thorium (Th) and '3U. . The initial driver was to provide an alternative fuel cycle in anticipation of a projected rapid growth in nuclear power, along with concern about a potential shortage of uranium to supply the ...
Introduction. Thorium reactors have been the subject of optimistic hype in recent years, with claims that they would be safer, produce less hazardous waste, be easier to find fuel for, and be harder to use for nuclear proliferation than traditional light-water uranium reactors.
Uranium and Thorium Compounds (Acetate and Nitrate) The Radiation Safety Office, managed by the Director of Radiation Safety, is responsible for assuring compliance with relevant Federal, State and University regulations and enforces policies established by the Radiation Safety Committee. The Radiation Safety Office maintains a staff adequate ...
Uranium-Thorium clockwork Uranium-Thorium dating is an absolute dating technique which uses the properties of the radio-active half-life of the two alpha emitters 238U and 230Th. The half-life of 238U is T 1/2=4,470,000,000 y. The half-life of 230Th is comparably short, only T 1/2=75,380 y. When the amounts of uranium and thorium are compared ...
Uranium and thorium occur in the shale, and radon is a daughter product of the uranium in phosphates within the shale. Black Shale outcrops in east central Kentucky contain uranium sulfates such as Zippeite, a yellow sulfate coating on some outcrops. The black shale also occurs in the subsurface in eastern and western Kentucky where it comes ...
Uranium or thorium compounds are substances or articles in which the U-235 concentration is no more than 0.72% by mass in the case of uranium, and the thorium is in its isotopic proportions found in nature. They include uranium and thorium metals. In the case of uranium…
