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 ...
English: A diagram showing the isotope signatures of natural ruthenium and fission product ruthenium from U-235 which had been subjected to thermal neutrons. Note that the Mo-100 (a long lived double beta emitter) has not had time to decay to Ru-100 over the time since the reactors stopped working.
Ruthenium is a chemical element; it has symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table . Like the other metals of the platinum group, ruthenium is unreactive to most chemicals.

Rhenium–osmium dating is a form of radiometric dating based on the beta decay of the isotope 187 Re to 187 Os.This normally occurs with a half-life of 41.6 × 10 9 y, [1] but studies using fully ionised 187 Re atoms have found that this can decrease to only 33 y. [2]
Ruthenium trichloride. The highest known ruthenium halide is the hexafluoride, a dark brown solid that melts at 54 °C.It hydrolyzes violently upon contact with water and easily disproportionates to form a mixture of lower ruthenium fluorides, releasing fluorine gas.
