One of the best (i.e. can detect smallest number of atoms) methods for
I-129 which is used n dating and environmental studies is accelarator mass
spectrometry (AMS).
With a good system at accelerating potentials of 1o MeV and multi-charged
ions ratios of I-129 to I-127 of 10-15 (1E-15) or less can be measured.
