    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 ...
