Radioactive carbon dating problems
There are three reasons why radiometric data is known to be accurate: 1.It depends upon radioactive decay, which is known to be extremely stable, not influenced my chemical processes, and which can be measured quite accurately.The actual accuracy of radiometric dating is about 2%, but there is no point in splitting hairs for this debate as to whether it is 2% or 3%.
Results from different techniques, often measured in rival labs, continually confirm each other.other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.Argon/argon dating works using only the ratio of the concentration of the argon isotopes. For the purposes of this debate, "accurate" means that 95% of the dating errors are within 10% of the measured date, within the time span for which the isotope pair is utilized.
Since carbon dating depends upon variable cosmic ray intensity, a calibration curve is assumed to be applied to account for that.Other methods do not require knowing the initial quantities.
