Bomb carbon peak dating
C has not actually disappeared, it has simply moved out of the atmosphere.The temporal variations of artificially high levels of atmospheric radiocarbon have been captured in organic material world-wide and thus offer an opportunity to determine a date of synthesis for biomolecules."The researchers measured the radiocarbon content in a minute fragment of unpainted canvas of the work, believed to be part of the Contraste de Formes series ...then plotted their results against the so-called 'bomb peak' curve," it says.
The art world's top experts and researchers have been trying to establish since the 1970s whether a painting believed to be part of the "Contraste de Formes" series produced by French artist Fernand Leger between 19 was genuine.
Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.
"It is now a certainty that the painting is a fake.
The enigma has now been solved," says the institute in a statement.
