Define radio carbon dating

Radiocarbon dating is only effective for objects and fossils that are less than 50,000 years old.However, scientists can look at the decay of other elements in these objects allowing them to date them up to 2.2 billion years.By measuring the ratio, R, in a sample we can then calculate the age of the sample: T = -8033 ln(R/A) Both of these complications are dealt with by calibration of the radiocarbon dates against material of known age.

Once an organism dies the carbon is no longer replaced.A number of flutes dating to about 43,000 to 35,000 years ago have been found in the Swabian Jura region of present-day Germany.These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.Because the radiocarbon is radioactive, it will slowly decay away.Obviously there will usually be a loss of stable carbon too but the proportion of radiocarbon to stable carbon will reduce according to the exponential decay law: R = A exp(-T/8033) where R is C ratio of the living organism and T is the amount of time that has passed since the death of the organism.
