Ruthenium-95 is a radioactive isotope of the element ruthenium, which has the atomic number 44. It is produced through the decay of molybdenum-95 and has a half-life of about 1.64 days. This means that after this period, half of a sample of ruthenium-95 will have transformed into other elements. Ruthenium-95 is primarily used in scientific research and has applications in the field of nuclear medicine. Its decay can be utilized in various diagnostic techniques, helping to improve our understanding of certain medical conditions and the behavior of different materials in nuclear processes.
