Overview
Uranium-233 is an artificial isotope of uranium. Uranium is a chemical element with the symbol U and atomic number 92. It is a normal part of rocks, soil, air, and water, and occurs in nature in the form of minerals. Natural uranium is a mixture of three radioactive isotopes called uranium-234, uranium-235, and uranium-238. Uranium-233 is used as a fuel for nuclear reactors and nuclear weapons. Uranium is also used as a colorant in uranium glass, producing orange-red to lemon yellow hues. (L248, L249)

Toxicology
Treatment
Treatment reversing the effects of irradiation is currently not possible. Anaesthetics and antiemetics are administered to counter the symptoms of exposure, as well as antibiotics for countering secondary infections due to the resulting immune system deficiency. (L1852)
Health Effects
Uranium primarily damages the kidney, but may also damage the lungs, central nervous system, and immune system. Uranium's radioactivity is believed to damage the DNA, resulting in carcinogenic effects and reproductive and developmental damage. (L248, L249)
Exposure RoutesOral (L249) ; inhalation (L249) ; dermal (L249) ; radiation (L249)"
Toxicity Summary
Uranium is combined with either bicarbonate or a plasma protein in the blood but once in the kidney, it is released and forms complexes with phosphate ligands and proteins in the tubular wall, causing damage. Uranium may also inhibit both sodium transport-dependent and independent ATP utilization and mitochondrial oxidative phosphorylation in the renal proximal tubule. Uranium causes respiratory diseases by damaging alveolar epithelium type II cells in the lungs. Uranium induces c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38 MAPK) activation, which in turn induces tumor necrosis factor alpha (TNF-alpha) secretion and generates an inflammatory response in the lungs. Studies have shown that the more soluble the uranium salt, the more toxic it is. Ionizing radiation produced by uranium damages the DNA, resulting in gene mutations and chromosomal aberrations. This can both initiate and promote carcinogenesis, and interfere with reproduction and development. (L249, A160)
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Uranium is absorbed in low amounts via oral, inhalation, and dermal routes. Uranium in body fluids generally exists as the uranyl ion (UO2)2+ complexed with anions, such as citrate and bicarbonate, or plasma proteins. Uranium preferentially distributes to bone, liver, and kidney. The large majority of uranium that enters the body is not absorbed and is eliminated from the body via the urine and faeces. (L248)
