what is the formula to determine the specific activity of radionulcide in sediments
Dear SirOne has to determine the activity of the radionuclide and the mass of the sediment. The specific activity of a given nuclide is unique and related to the decay constant.
One might attempt to separate the given element from the sediment and measure the mass, or perhaps measure the quantity (or proportion) present by emission spectroscopy.
