WebBecause the half-life is different with U238 and U235, the higher the percentage of U235 so retroactively. The enrichment ratio of U235 to be used in a nuclear reactor is about 3%, it is the same as the existing ratio of U235 2 billion years ago. The presence of natural reactor was predicted and found for this reason. WebThe half-life of a radioactive substance is the time H that it takes for half of the substance to change form through radioactive decay. This number does not depend on the amount with which you start. For example, carbon-14 is known to have a half-life of H = 5770 years. Thus if you begin with 1 gram of carbon-14, then 5770 years later you will ...
