How many isotopes of uranium are there
WebUses. Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made. Naturally occurring uranium consists of 99% uranium-238 and 1% uranium-235. WebFor example, technetium-99m, one of the most common medical isotopes used for imaging studies, has a half-life of 6 hours. The short half-life of technetium-99m helps keep the dose to the patient low. After 24 hours, …
