  2. Isotopes of ruthenium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_ruthenium

    Naturally occurring ruthenium (44 Ru) is composed of seven stable isotopes (of which two may in the future be found radioactive). Additionally, 27 radioactive isotopes have been discovered. Of these radioisotopes, the most stable are 106 Ru, with a half-life of 373.59 days; 103 Ru, with a half-life of 39.26 days and 97 Ru, with a half-life of 2 ...

    Because of their long half-lives, such isotopes are still found on Earth in various quantities, and together with the stable isotopes they are called primordial isotopes. All the primordial isotopes are given in order of their decreasing abundance on Earth. [c] For a list of primordial nuclides in order of half-life, see List of nuclides.

    The ruthenium in PUREX raffinate can become oxidized to form volatile ruthenium tetroxide which forms a purple vapour above the surface of the aqueous liquor. The ruthenium tetroxide is very similar to osmium tetroxide; the ruthenium compound is a stronger oxidant which enables it to form deposits by reacting with other substances. In this way ...
