Carbon-Dating In Forensic Science
Carbon-dating in forensic science Forensic scientists can compare the concentration of carbon (radiocarbon) in tooth samples to known radiocarbon levels during specific time periods and estimate the date of birth. Using other types of tissues, such as blood, hair, or nails, researchers can predict the year of death of a person.

Jan 01, · The concentration of radiocarbon (carbon or 14 C) in materials of biological origin can be used to determine the age of the material. Traditional 14 C dating quantifies the depletion in 14 C since death and is widely used to date bones older than years. Atmospheric testing of nuclear weapons during the s and early s temporarily doubled the natural concentration of 14 C in .
Forensic experts use radiocarbon dating to establish if an individual died recently (perhaps a matter for the Justice Department) or in antiquity (a matter for the archaeologist). They do this by using the “ bomb carbon ” curve. Bomb Carbon, A Tracer for Recent Studies Living things assimilate radiocarbon from .
Radiocarbon dating is possible because of the existence in nature of the radioactive isotope 14 C (albeit in small quantities; the vast majority of natural carbon is composed of the stable isotopes 13 C and 12 C). This isotope has the advantages for the study of the human past of a conveniently long half-life (of ∼ years, although by convention radiocarbon results are calculated on the.
