Abstract: Atmospheric testing of nuclear weapons during the 1950s and early 1960s doubled the concentration of carbon-14 in the atmosphere and created a pulse that labeled everything alive since 1955 as carbon moved up the food chain. 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.
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.
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.
A chapter which specifies management measures to protect coastal waters from silvicultural sources of non point pollution. Contains ten management measures that address various phases of forestry operations.
This chapter contains management measures that address multiple categories of nonpoint source (NPS) pollution that affect coastal waters. These pollutants include sediment, nitrogen, phosphorus, and temperature.
