Radiocarbon dating uses carbon-14 to determine the last time something (or someone) was alive. Carbon-14 originates in the upper atmosphere of the earth and is created when neutrons originating from solar radiation bombardment collide with nitrogen in the air. A reaction occurs and a tiny number of these collisions convert nitrogen to carbon-14.
