Temporal variations in C was artificially produced when hundreds of nuclear test weapons were detonated in the atmosphere, mostly in the Northern Hemisphere, in the late 1950s and early 1960s.
The difference of the two curves (R) is ~400 yr on average.
Details An example of bomb-pulse radiocarbon dating of a terrestrial sample from Northern Hemisphere zone 1.
For the remaining period 12,400-26,000 cal yr BP, the curve is derived from independently dated marine samples such as foraminifera and corals.
A new internationally-ratified calibration curve (Int Cal09) covering the whole radiocarbon timescale (~50,000 cal yr) is being prepared by the Int Cal Working Group.
For a radiocarbon value measured in a sample S (Fs), bomb radiocarbon delivers two possible calendar dates (T1 and T2), indicated by the grey boxes (Hua, 2009).
