Exempel på uranium

• This is no doubt related to the increased interest in gas centrifuges as a means of separating uranium isotopes.

• It has therefore been concluded that, it is necessary to develop an alternate target design for such high intensities of the uranium beam.

• Uranium content, determined from the spectral gamma-ray, attains its highest concentrations in this lithology.

• Previous experiments with the short chamber used other kinds of ions, for example gold and uranium.

• Uranium is very susceptible to oxidation, which is bad for two reasons.

• Most likely the organic matter is derived from the carbon- and uranium-rich bituminous shale of the target.

• The uranium solution was a twofold dilution of a saturated solution.

• Uranium is also important to the development of nuclear power in an advanced civilization.

• Within 15-30 s an equal amount of uranium acetate solution was dropped on the sample.

• The uranium could be derived from the shale or from the granite itself.

• A major omission for geologists exploring in 2006 is the general lack of discussion of iron, manganese, nickel, uranium and tungsten deposits.

• Lower uranium contents of the less organic-rich mudstones indicate that oxygen levels were probably increased during their deposition.

• Consequently, uranium is not used for petrogenetic interpretation in this study.

• Erosion of the granites yields specific minerals including quartz, radioactive (uranium-, thorium-bearing) phases and phosphates, which could play a role in early evolution.

• In analogy, the macroproperty of half-life may be attributed to uranium.
