These factors affect all trees in an area, so examining tree-ring sequences from old wood allows the identification of overlapping sequences.

Radiocarbon dating age range

Suess said he drew the line showing the wiggles by "cosmic schwung" – freehand, in other words.

It was unclear for some time whether the wiggles were real or not, but they are now well-established.

To produce a curve that can be used to relate calendar years to radiocarbon years, a sequence of securely dated samples is needed which can be tested to determine their radiocarbon age.

The study of tree rings led to the first such sequence: tree rings from individual pieces of wood show characteristic sequences of rings that vary in thickness because of environmental factors such as the amount of rainfall in a given year.

When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.
