WebThe term “specific activity” is defined as the amount of radioactivity – or the decay rate – of a particular radionuclide per unit mass of the radionuclide. For example, the specific activity of Ra-226 is 1, meaning that one gram of Ra-226 contains one (1) curie (assumed to be uniformly distributed throughout that mass).
