Book Description
Although there is a growing need for neutron and gamma irradiations by governmental and industrial organizations in the United States and in other countries the number of facilities providing such irradiations are limited. At the Idaho National Engineering Laboratory, there are several unique irradiation facilities producing high neutron and gamma radiation environments. These facilities could be readily used for nuclear research, materials testing, radiation hardening studies on electronic components/circuitry and sensors, and production of neutron transmutation doped (NTD) silicon and special radioisotopes. In addition, a neutron radiography unit, suitable for examining irradiated materials and assemblies, is also available. This paper provides a description of the irradiation facilities and the neutron radiography unit as well as examples of their unique applications.

Book Description
Heavy-ion bombardment provides a method for simulating neutron damage to metals and other materials. Simultaneous implantation of He ions allows the study of effects of neutronically generated helium in these samples. A 2-MeV Van de Graaff and a 2-MeV tandem accelerator at Battelle, Pacific Northwest Laboratories (PNL) have been combined to provide dual-beam irradiation with heavy ions, Ni/sup + +/ or Ta/sup + +/, and with He+ ions. This irradiation facility allows independent control of beam currents and energies for both heavy-ion and helium-ion beams, as well as sample temperatures to 1200°C. It will be used both for investigation of materials for advanced reactor applications and for basic studies of radiation damage mechanisms. Preliminary results on molybdenum irradiated to two dose levels at 1000°C, with and without simultaneous helium implantation, show the effect of helium on void nucleation. When helium is continuously implanted, the number of voids increases with dose. Without helium, existing voids grow in size but the number is unchanged. At higher heavy-ion dose rates, this effect of helium is less pronounced.
Molybdenum-99 for Medical Imaging

Book Description
The decay product of the medical isotope molybdenum-99 (Mo-99), technetium-99m (Tc-99m), and associated medical isotopes iodine-131 (I-131) and xenon-133 (Xe-133) are used worldwide for medical diagnostic imaging or therapy. The United States consumes about half of the world's supply of Mo-99, but there has been no domestic (i.e., U.S.-based) production of this isotope since the late 1980s. The United States imports Mo-99 for domestic use from Australia, Canada, Europe, and South Africa. Mo-99 and Tc-99m cannot be stockpiled for use because of their short half-lives. Consequently, they must be routinely produced and delivered to medical imaging centers. Almost all Mo-99 for medical use is produced by irradiating highly enriched uranium (HEU) targets in research reactors, several of which are over 50 years old and are approaching the end of their operating lives. Unanticipated and extended shutdowns of some of these old reactors have resulted in severe Mo-99 supply shortages in the United States and other countries. Some of these shortages have disrupted the delivery of medical care. Molybdenum-99 for Medical Imaging examines the production and utilization of Mo-99 and associated medical isotopes, and provides recommendations for medical use.
