medical isotope production without highly enriched uranium
this book is the product of a congressionally mandated study to examine the feasibility of eliminating the use of highly enriched uranium heu2 in reactor fuel reactor targets and medical isotope production facilities . the book focuses primarily on the use of heu for the production of the medical isotope molybdenum 99 mo 99 whose decay product technetium 99m3 tc 99m is used in the majority of medical diagnostic imaging procedures in the united states and secondarily on the use of heu for research and test reactor fuel . the supply of mo 99 in the u.s. is likely to be unreliable until newer production sources come online . the reliability of the current supply system is an important medical isotope concern ; this book concludes that achieving a cost difference of less than 10 percent in facilities that will need to convert from heu to leu based mo 99 production is much less important than is reliability of supply .
