Radiocarbon dating test
Eventually, all the carbon-14 in the remains will disappear.
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.
This process is constantly ongoing, so that at any point in time the amount of carbon-14 in living plants is the same as the amount of carbon-14 in the air around them.
Living plants are active components of the overall food chain.
Radiocarbon dating is applicable to biobased content measurements in manufactured products because they contain some combination of recently living materials and fossil materials.
