Gold-198 ( Au) is a radioactive isotope of gold. It undergoes beta decay to stable Hg with a half-life of 2.69464 days. The decay properties of Au have led to widespread interest in its potential use in radiotherapy for cancer treatments. This isotope has also found use in nuclear weapons research and as a radioactive tracer … See more Au was possibly observed for the first time in 1935 by Enrico Fermi et al., though it was not correctly identified at the time. This isotope was conclusively identified in 1937 following neutron irradiation of stable Au and was ascribed a half … See more • Isotopes of gold See more Nuclear medicine Au is used for radiotherapy in some cancer treatments. Its half-life and beta decay energy are favorable for use in medicine because its 4 mm penetration range in tissue allows it to destroy tumors without nearby non … See more WebVarious isotopes, including gold-198, iridium-192, iodine-125, and cesium-131, are used for their various intensity and half-life properties. Different isotopes have different radiation effects, including the intensity of the radiation, the distance it penetrates and the length of time the isotope is actively emitting radiation.
