(a) In a sample of 1000 atoms,if 50 atoms decay in 5seconds, what is the radioactivity measured in mCi, of the sample? b) in order to produce a level of radioactivity of 1mCi, how many nuclei of 99mTc ( ? = 3.22X10^(-5)s^(-) ) must be present? What mass of the radionuclide does this correspond to?(Avogadro’s […]
