Uranium and Plutonium are highly reactive elements that undergo not only chemical reactions but also nuclear reactions. This can lead to possibly significant materials degradation, a matter of potentially great concern. Here, the issue of the electronic structure changes that occur with oxidation and radiological aging will be addressed, in a fairly empirical manner. In essence, the sensitivity of various electron spectroscopic techniques to oxidation and aging will be surveyed and discussed, including the apparent limitations. It will be found that 5d and 4d X-ray absorption and electron energy loss are essentially blind to the changes corresponding to oxidation and aging in U and Pu.
