A technique that uses the intrinsic mass‐based separation capability of a quadrupole mass spectrometer has been used to resolve spectral radiometric interference of two isotopes of the same element. In this work the starting sample was a mixture of 137 Cs and 134 Cs and was (activity) dominated by 137 Cs. This methodology separated and ‘implanted’ 134 Cs that was later quantified for spectral features and activity with traditional radiometric techniques. This work demonstrated a 134 Cs/ 137 Cs activity ratio enhancement of >4 orders of magnitude and complete removal of 137 Cs spectral features from the implanted target mass (i.e. 134).
