Abstract
nuclear powerplant and continue to contaminate the exclusion zone in northern Ukraine. Isotopic analysis can
provide vital information about sample origin, history and contamination of the environment, though it has been
underutilized due to the destructive nature of most mass spectrometric techniques, and inability to remove
isobaric interference. Recent developments have diversified the range of elements that can be investigated
through resonance ionization mass spectrometry (RIMS), notably in the fission products. The purpose of this
study is to demonstrate the application of multi-element analysis on hot particles as relates to their burnup,
particle formation in the accident, and weathering. The particles were analysed with two RIMS instruments:
resonant-laser secondary neutral mass spectrometry (rL-SNMS) at the Institute for Radiation Protection and
Radioecology (IRS) in Hannover, Germany, and laser ionization of neutrals (LION) at Lawrence Livermore Na-
tional Laboratory (LLNL) in Livermore, USA. Comparable results across instruments show a range of burnup
dependent isotope ratios for U and Pu and Cs, characteristic of RBMK-type reactors. Results for Rb, Ba and Sr
show the influence of the environment, retention of Cs in the particles and time passed since fuel discharge.
