Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide.This transformation may be accomplished in a number of different ways, including alpha decay (emission of alpha particles) and beta decay (electron emission, positron emission, or electron capture).

Just go to Settings, then Privacy and check the boxes for "Back Up My Data" and "Automatic Restore." This way, if the upgrade goes badly and you have to reset your OS, at least everything from photos to apps and settings will be saved off your tablet.
