This means that you must be sure to notify EHS about your orders and inventory of uranium and thorium. Planning to Use Uranium or Thorium. Consult with the Radiation Safety Officer (RSO) before ordering or using uranium or thorium, even if you only plan to use very small amounts or concentrations.
Thorium - LewRockwell
Thorium metal has long been available from commercial industrial suppliers, having uses in welding and gas lighting. In contrast, virgin uranium metal has never been available commercially (in the U.S., all of it is owned by the federal government). Thorium is similar to Uranium.

Thorium | GoldisMoney, The Premier Gold and Silver ...
Dec 19, 2019 · Thorium is similar to Uranium. They are the only two elements found in nature that can absorb neutrons and transmute into fissile elements. Thus, they are both fertile elements that can be used to fuel nuclear reactors. But unlike uranium, thorium-reactors cannot be started without the addition an autonomous neutron source mixed with the fuel.
Uranium - Wikipedia
Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), decays to lead-206 through a series of relatively short-lived isotopes. Uranium-233 is made from thorium-232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.
Occurrence of thorium - Wikipedia
Thorium-containing minerals occur on all continents. Thorium is several times more abundant in Earths crust than all isotopes of uranium combined and thorium-232 is several hundred times more abundant than uranium-235. Thorium concentrations near the surface of …
Thorium - Wikipedia
Uranium–thorium dating is commonly used to determine the age of calcium carbonate materials such as speleothem or coral, because uranium is more soluble in water than thorium and protactinium, which are selectively precipitated into ocean-floor sediments, where their ratios are measured. The scheme has a range of several hundred thousand years.
Whats the Difference Between Thorium and Uranium Nuclear ...
Thorium-fueled reactors, on the other hand, are fuel-efficient, almost perfectly so, but that comes at the end of a three-phase process, with the first phase shared by thorium and uranium fuel ...
TENORM: Oil and Gas Production Wastes | Radiation ...
While uranium and thorium are not soluble in water, ... If equipment cannot be further decontaminated to acceptable levels, it is sent to a landfill licensed to accept NORM materials. TENORM contamination in U.S. oil production waste came to the attention of industry and government in 1986.
Uranium & Thorium Sputter stone SOP
Note: Equipment, used for sputtering, which may become contaminated with uranium and thorium are marked with red tape or standard radiation stickers. Effort should be made to NOT remove contaminated items from designated areas except as transported in the proper designated container. This is to eliminate contamination to other areas.
PART 110—EXPORT AND IMPORT OF NUCLEAR EQUIPMENT AND …
Dec 23, 2019 · (1) Natural or depleted uranium, or thorium, other than special nuclear material; or (2) Ores that contain by weight 0.05 percent or more of uranium, thorium or depleted uranium. Special nuclear material means plutonium, uranium-233 or uranium enriched above 0.711 percent by weight in the isotope uranium-235.
Isotopes of thorium - Wikipedia
Thorium-232. 232 Th is the only primordial nuclide of thorium and makes up effectively all of natural thorium, with other isotopes of thorium appearing only in trace amounts as relatively short-lived decay products of uranium and thorium.

They could also dissolve both uranium and thorium in their fluoride-salt mixtures, and the mixtures were impervious to radiation damage due to their ionic bonds. ... This leads to large equipment ...
Prospecting for Uranium With Car-Mounted Equipment
PROSPECTING FOR URANIUM WITH CAR-MOUNTED EQUIPMENT 213 rocks in the area have a radioactivity of 0.005 percent equivalent uranium or more. Radioactivities in this higher range are called abnormal and indicate an abnormally high concentration of uranium or thorium in the rock.

calcium, zinc, sodium, lithium, potassium, sodium/potassium alloys, uranium, thorium and pluto-nium, can be explosion hazards under the right conditions. Some of these metals are almost exclu-sively laboratory materials but because of where they are used, fire service personnel must be trained to handle emergency situations.
