The variation in carbon-14 concentration in time is well-documented and can be used to chronologically date all biological materials since the mid-1950s.</p>Radiocarbon Dating2016-05-19T09:45:19-05:00https://digital.library.unt.edu/ark:/67531/metadc842772/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc842772/"><img alt="Radiocarbon Dating" title="Radiocarbon Dating" src="https://digital.library.unt.edu/ark:/67531/metadc842772/thumbnail/"/></a></p><p>Abstract: Radiocarbon dating can be used to determine the age of objects that contain components that were once alive. In the case of human remains, a radiocarbon date can distinguish between a crime scene and an archaeological site. Documents, museum artifacts and art objects can be dated to determine if their age is correct for the historical context. A radiocarbon date does not confirm authenticity, but it can help identify a forgery.</p>Lead-Cooled Fast Reactor (LFR) Design: Safety, Neutronics, Thermal Hydraulics, Structural Mechanics, Fuel, Core, and Plant Design2016-05-19T15:16:37-05:00https://digital.library.unt.edu/ark:/67531/metadc840495/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc840495/"><img alt="Lead-Cooled Fast Reactor (LFR) Design: Safety, Neutronics, Thermal Hydraulics, Structural Mechanics, Fuel, Core, and Plant Design" title="Lead-Cooled Fast Reactor (LFR) Design: Safety, Neutronics, Thermal Hydraulics, Structural Mechanics, Fuel, Core, and Plant Design" src="https://digital.library.unt.edu/ark:/67531/metadc840495/thumbnail/"/></a></p><p>Fifth chapter from "A Compendium of Reactor Technology" discussing the history and design of lead-cooled fast reactors in nine sections: Lead-cooled Fast Reactor (LFR) Development, Design Criteria and General Specifications, Neutronics, Lead Properties, Compatibility of Structural Materials with Lead, Core, Reactor System, Decay Heat Removal System, and Nuclear Island.</p>
