Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.
Other methods do not require knowing the initial quantities.
An error of 90% would, for example, still disprove Young Earth Creationism.
There are three reasons why radiometric data is known to be accurate: 1.
By analogy, a stop watch will not keep accurate time if it is not wound, if it is not in good repair, or if the operator forgets to press the button.
Methods are precise insofar as they are properly used.
These effects are outlined using two areas sampled for radiocarbon dating at Pagan: the fortifications near the Tharaba Gate and a site within the old city walls, Inventory No. KEYWORDS: Pagan, Bagan, Burma, Myanmar, radiocarbon, fire, fortifications, absolute chronology, calibration.
