Before revision: According to some research the ruthenium is very mobile when the nuclear fuel is heated with air.Zoltán Hózer, Lajos Matus, Oleg Prokopiev, Bálint Alföldy and Mrs Anna Csordás-Tóth Escape Ruthenium With High Temperature Air , KFKI Atomic Energy Research Institute, November, 2002 This mobility has been more evident in reprocessing, with related releases of Ruthenium , the most recent being the Airborne radioactivity increase in Europe in autumn 2017, as with the ionizing radiation environment of spent fuel and the presence of oxygen, radiolysis-reactions can generate the volatile compound Ruthenium (VIII) oxide, which has a boiling point of approximately and is a strong oxidizer, reacting with virtually any fuel/hydrocarbon, that are used in PUREX.
