As soon as it became aware of the first detections of Ruthenium 106 in the atmosphere in Italy on 3
October, 2017, IRSN mobilized all its means of radiological monitoring of the atmosphere and
conducted regular analysis of the filters from its monitoring stations2. For the period from
September 27 to October 13, only the stations of Seyne-sur-Mer, Nice and Ajaccio revealed the
presence of Ruthenium 106 in trace amounts. During this period, the highest value (46 microBq/m3),
was recorded in Nice between 2 and 9 October. Since October 13, 2017, Ruthenium 106 is
no longer detected in France. All IRSN measurement results between September 26 and October 19
are presented in Appendix 1.
