Nuclear forensic analysis of an unknown uranium ore concentrate sample
Normalised rare earth element patterns have been shown to be valuable in attributing unknown samples of uranium ore and ore concentrates [3], [6]. Fig. 6 shows the chondrite-normalized rare earth element concentrations (using ANSTO values) of NSR-F-130509 and UOC and ore obtained from Mary Kathleen along with the UOCs from a …

Geology of Uranium Deposits
The major primary ore mineral is uraninite (basically UO 2) or pitchblende (U 2 O 5.UO 3, better known as U 3 O 8), though a range of other uranium minerals are found in particular deposits. These include carnotite (uranium potassium vanadate), the davidite-brannerite-absite type uranium titanates, and the euxenite-fergusonite-samarskite group ...

Uranium Ore Samples
These samples of uranium ore were sold at the American Museum of Atomic Energy in Oak Ridge, Tennessee, sometime during the 1950s or 1960s. Each plastic case is 1 1/8" x 1 1/8" x 5/8" in size. During tours of the Museum, visitors would stop at the gift shop (don't all tours end at a gift shop?) where the ore samples and other items would be sold.

Radionuclide Basics: Uranium | US EPA
Uranium (chemical symbol U) is a naturally occurring radioactive element. When refined, uranium is a silvery-white metal. Uranium has three primary naturally occurring isotopes isotopesA form of an element that has the same number of protons but a different number of neutrons in the nucleus, giving it a different atomic mass. For …

A comparison of analytical methods for determining uranium and …
In the untreated ore sample T-O-F, uranium is mainly bound in uraninite which is principally enclosed in carbonaceous nodules. Small amounts of uranium were also found in monazite and xenotime (YPO 4), whereas thorium is mostly bound in uraninite. Nitric acid was found to be the most efficient digestion agent for extraction of …

FAQ | Uranium Store
Uranium is a mildly radioactive heavy metal. The radiation coming from natural uranium is a mix of alpha, beta and gamma radiation. It might cause a health hazard if one was to ingest a large portion of uranium or breath in dust from the ore samples. Handling the ore samples with gloves is recomended.

Uranium Ore
Samples from uranium ore in Oklo had 235 U content as low as 0.440% – a significant difference from the current natural content. Examination of other isotopes showed similar anomalies, such as neodymium and ruthenium, which indicated that at least 16 natural nuclear reactors operated about 1.7 billion years ago for a period of 200–600 ...

These two isotopes might produce an intense gamma signal even when uranium is not present, or with a much smaller activity, in the ore. Therefore, gamma spectroscopy measurements of core samples are performed on the surface with HPGe detectors to directly characterize uranium activity from the 1001-keV gamma ray of 234 mPa that is …
