These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.
Unlike other radiometric dating techniques where it is not possible to calibrate the method against historically-known dates, limited calibration is possible for carbon dating.
That is, samples with dates known from historical records can be used to check the accuracy of the method.
Despite this, however, caution is still necessary in accepting dates derived from carbon dating.
C must be younger than 50,000 to 100,000 years, assuming that adequate precautions have been taken to eliminate contamination.
Carbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.This is used in chemical research in a technique called carbon labeling: some carbon-12 atoms of a given compound are replaced with carbon-14 atoms (or some carbon-13 atoms) in order to trace them along chemical reactions involving the given compound.Carbon-14 is produced in the upper layers of the troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms.Carbon dating, or carbon-14 dating, is a method for comparing the ages of organic materials such as bones or artifacts made from anything that once lived.Unlike many other radiometric dating methods, carbon dating has been calibrated for historical periods and within that range can give reliable results.An animal that ingested plants with relatively low C-14 proportions would be dated older than their true age." Dating laboratories do not make any allowance for the change in atmospheric levels that would have occurred as a result of Noah's Flood.Tags: Adult Dating, affair dating, sex dating
