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). WebThe specific activity (SA) values determined using two different methods were compared for a set of tritium-labeled and carbon-14-labeled compounds. The methods employed were as follows: (a) liquid chromatography/mass spectrometry (LC/MS) isotopic peak intensity distribution, and (b) determination of the tracer mass concentration using ... family medicine lafayette co https://mikroarma.com
