title: Mass selective separation applied to radioisotopes of cesium.
abstract: 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 of137Cs and134Cs and was (activity) dominated by137Cs. This methodology separated and 'implanted'134Cs that was later quantified for spectral features and activity with traditional radiometric techniques. This work demonstrated a134Cs/137Cs activity ratio enhancement of >4 orders of magnitude and complete removal of137Cs spectral features from the implanted target mass (i.e. 134).
