Iron-55 ( Fe) is a radioactive isotope of iron with a nucleus containing 26 protons and 29 neutrons. It decays by electron capture to manganese-55 and this process has a half-life of 2.737 years. The emitted X-rays can be used as an X-ray source for various scientific analysis methods, such as X-ray diffraction. Iron-55 is … See more Iron-55 decays via electron capture to manganese-55 with a half-life of 2.737 years. The electrons around the nucleus rapidly adjust themselves to the lowered charge without leaving their shell, and shortly thereafter … See more • Isotopes of iron See more The K-alpha X-rays emitted by the manganese-55 after the electron capture have been used as a laboratory source of X-rays in various See more Iron-55 is most effectively produced by irradiation of iron with neutrons. The reaction ( Fe(n,γ) Fe and Fe(n,2n) Fe) of the two most … See more WebIron is retained in organs and tissues with a biological half-life of 2000 days(3). One or two percent of an uptake of 55Fe is eliminated in urine during the first 24 hours, the rest of the uptake is eliminated in feces(4). Decay table Physical half-life: 2.7 years(1).
