Is radiometric age dating accurate maddox not updating

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%.

An error of 90% would, for example, still disprove Young Earth Creationism.

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.

There are three reasons why radiometric data is known to be accurate: 1.

Uranium 235 decay to lead has a half-life of 713 million years, so it is well suited to dating the universe.Measuring the ratio of C14 to C12 and C13 therefore dates the organic matter for periods back to about eight half-lives of the isotope, 45,000 years.After a long enough time the minority isotope is in an amount too small to be measured.For dating back to about 35,000 years, sediment layers are precise. Sediments include different types of pollen depending upon the season.Consequently, individual years can be identified by season, so there is no possibility of layers being confused.
