Iodine-125 ( I) is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat a number of conditions, including prostate cancer, uveal melanomas, and brain tumors. It is the second longest-lived radioisotope of iodine, after iodine-129. Its … Visa mer I is a reactor-produced radionuclide and is available in large quantities. Its production follows the two reactions: Xe (n,γ) → Xe (57 s) → I (59.4 d) Xe (n,γ) → Xe (19.9 h) → I (59.4 d) The irradiation … Visa mer The detailed decay mechanism to form the stable daughter nuclide tellurium-125 is a multi-step process that begins with electron capture. This is followed by a cascade of electron relaxation as the core electron hole moves toward the valence orbitals. The cascade … Visa mer Iodine-125 is commercially available in dilute NaOH solution as I-iodide (or the hypohalite sodium hypoiodite, NaIO). The radioactive … Visa mer As of October 2024, there were two producers of iodine-125, the McMaster Nuclear Reactor in Hamilton, Ontario, Canada; and a research reactor in Uzbekistan. The McMaster reactor is presently the largest producer of iodine-125, producing … Visa mer • Isotopes of iodine • Iodine-123 • Iodine-129 • Iodine-131 • Iodine in biology Visa mer Indium (49In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide ( In) being measurably though weakly radioactive. Its spin-forbidden decay has a half life of 4.41×10 years. The stable isotope In is only 4.3% of naturally occurring indium. Among elements with a known stable isotope, only tellurium and rhenium similarly occur with a stable isotope in lower abundanc…

Webb13 jan. 2016 · 2n = 16 ⇒ n = 4 Therefore, four half-lives must pass in order for the activity of the sample to go from 880 Bq to 55 Bq. Since the number of half-lives can be thought of as n = given period of time half-life = t t1/2 you can say that t1/2 = t n This will get you t1/2 = 160 minutes 4 = 40. minutes Answer link WebbIodine-131 has a half-life of about 8 days. Express your answer using two significant figures. The half-life of iodine-131 is 8.02 days. How long would it take for 10% of a sample to decay in hours?
