Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/books/NBK215133/ | https://www.iaea.org/OurWork/ST/NE/NEFW/Technical-Areas/RRS/documents /mo99/WORKINGMATERIALSmo99CM.pdf | https://www.ncbi.nlm.nih.gov/pubmed/27854401

Molybdenum-99 (99Mo, half-life = 66 h) is a parent radionuclide of a diagnostic nuclear isotope. It decays in technetium-99 m (half-life = 6 h), which is used in over 30 million procedures per year around the world. Between 95 and 98 percent of Mo-99 is currently being produced using highly enriched uranium (HEU) targets. Other medical isotopes such as iodine-131 (I-131) and xenon-133 (Xe-133) are by-products of the Mo-99 production process and will be sufficiently available if Mo-99 is available.
