During the late 1950s and early 1960s, thermonuclear tests added considerable amounts of 14C to the atmosphere. Since that time the amount has declined, which is owed to the exchange and dispersal of 14C into the Earth's carbon reservoirs, creating an isotopic chronometer (the 14C bomb peak) to all living organisms. In this study, we make use of this alternative radiometric method to compare dendrochronological...
