A radioactive metallic element that does not occur naturally in its pure form but is widely found in ores such as pitchblende, carnotite, and uraninite. Radioactive decay of uranium yields a series of radioactive products, including radium and radon. During the various decay stages, radiation is emitted. Uranium is also poisonous.
Breakdown of the nuclei of some elements resulting in the emission of energy in the form of alpha, beta and gamma rays. Because of this particle emission, the elements decay into other elements. Radium and uranium are naturally occurring radioactive elements. RADIOTHERAPY treatment utilises arti?cially produced isotopes (alternative forms of an element) such as iodine-131 and cobalt-60.... radioactivity
A collection of varying symptoms, such as persistent tiredness, headaches, muscle pain and poor concentration, reported by members of the Coalition Armed Forces who served in the 1991 Gulf War. Whilst there is strong evidence for a health e?ect related to service, there is no evidence of a particular set of signs and symptoms (the de?nition of a ‘syndrome’) unique to those who served in the Gulf War. Symptoms have been blamed on multiple possible hazards, such as exposure to depleted uranium munitions, smoke from oil-well ?res and use of pesticides. However, the only clearly demonstrated association is with the particular pattern of vaccinations used to protect against biological weapons. Many con?icts in the past have generated their own ‘syndromes’, given names such as e?ort syndrome and shell-shock, suggesting a link to the psychological stress of being in the midst of warfare.... gulf war syndrome
