Carbon dating forensic science
The problems Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used.
Until now, document dating methods have been able to indicate whether the writing was relatively new (less than 90 days) or older (over two years), yet this chronological accuracy is insufficient in certain cases, above all in judicial ones.
When analysing the kinetics involved in its disappearance, the research group established a pattern that links the state of the ink with the time that has elapsed.
In fact, the dating of documents is a key area in the field of forensic science. These are often very tricky questions to answer and frequently arise in judicial contexts.
