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.
This book chapter discusses educating communities. and preserving tomorrow's treasures today. Librarians, curators, archivists, and volunteers work hard to conserve and preserve materials as they are added to their collections, insuring that the materials can be safely used. However, not all genealogical and historical information is held in cultural institutions; unknown numbers of valuable information sources reside with individuals and in residences. By educating the community today on how to protect the treasures in their care, we have the potential to minimize the repairs needed for these items in the future.
