There are many sports restricted to players of a certain age (e.g.16 and under, 18 and under, etc.) What if a person is older and fakes his birth certificate to say that he is younger? Can we determine such a person's age by radiocarbon dating methods or other means? That doesn't mean we can't make a decent guess by other methods.She looked like a teenager and acted like a one too. A twenty-something guy passed himself off as a 14 year old. In children and adolescents, the combination of a dental exam, dental films and bone X-rays can narrow a one's biological age well.Once the bones are done growing in length, that avenue is closed. Chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and fairly precise results.Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects.
Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).
Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.
Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time it takes for its in the atmosphere, which attained a maximum in 1963 of almost twice what it had been before the testing began.
BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.
What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?
