Abstract :
Calculations of 154Eu and 155Eu activities in the Chernobyl Unit IV reactor are given, together with a discussion of the uncertainties involved and comparison with results of other authors. The measurements of activities of the Chernobyl-origin ‘fuel-like’ hot particles (fuel fragments) and analysis of the radionuclide fractionation reveal a common behaviour of 154Eu, 155Eu and 144Ce radioisotopes as regards non-volatility, similar to 95Zr and 95Nb in hot particles.
