Abstract: The connection between the fluorine in the particles and their age has been investigated. The influence of ultraviolet light exposure combined with the time elapsed after preparation has been investigated on uranium oxyfluoride particles prepared at the IRMM using an aerosol deposition chamber. The presence of fluorine in particles was confirmed by energy-dispersive X-ray analysis. Semi-quantititative information was obtained by evaluating peak height ratios obtained by secondary ion mass spectrometry. Possible correlations existing between the amount of fluorine and the particle age could be investigated, taking into account the environmental conditions to which the uranium oxyfluoride particles were exposed.
