atomic number 92,U metal,metallic element- any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc. uranium 235- a uranium isotope with mass number 235; capable of sustaining chain reactions ...
Uranium-238, however, after absorbing neutrons and undergoing negative beta decay, is transmuted into the synthetic element plutonium, which is fissile with slow neutrons. Natural uranium, therefore, can be used in converter and breeder reactors, in which fission is sustained by the rare uranium-...
A search of current nuclear data libraries has identified some inconsistencies in reported gamma line intensities for this decay chain. This paper is a report on the work carried out at BNFL and MAFF to confirm the correct intensities for 234 Th and 234m Pa....
PackingGroupCommercial HS Code28441000 Hazardous Substances Data7440-61-1(Hazardous Substances Data) ToxicityThree isotopes (234U, 235U, 238U) exist, and a large number of uranium salts are known. They present both toxic and radiological hazards. The most important use of uranium is in the nuclea...
Uranium Dioxide is a fuel material used in nuclear reactors that undergoes radiation effects due to exposure to various damage sources, resulting in the creation and evolution of defects through microscopic physical processes.

Uranium (pronounced /jʊˈreɪniəm/ yoo-RAY-nee-əm) is a silvery-white metallic chemical element in the actinide series of the periodic table with atomic number 92. It is assigned the chemical symbol U. A uranium atom has 92 protons and 92 electrons. 6 of the latter are val...
when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-236, which occurs in trace quantities due to neutron capture on 235U and as a decay product of plutonium-244;[114] and finally, uranium-233, which is formed in the decay chain of neptunium-...

uranium 235- a uranium isotope with mass number 235; capable of sustaining chain reactions uranium 238- the commonest isotope of uranium; it is not fissionable but when irradiated with neutrons it produces fissionable plutonium 239 pitchblende,uraninite- a mineral consisting of uranium oxide and ...
Moreover, quantities calculated from these results were rounded according to the number of significant digits. With regard to the amount of radioisotope produced, all data collected from these papers were converted to activities at the end of the bombardment in order to present all results in the...
