Radiometric dating accuracy wiki
As any first-year student of algebra soon learns, a single equation with two unknown variables cannot be solved.
In fact, the above formula is far too simple, because it assumes that the amount of daughter isotope was zero at start.
But new research by creationists has revealed a large number of problems with radiometric dating.
In some cases such as Carbon-14 dating, radioactive dating actually gives strong evidence for a young Earth.
If greater likelihood is sought, we could look at the interval 30 \pm 80$ years, encompassing two standard deviations, and the likelihood that the half-life of a given sample of Carbon $ will fall in this range is a little over $ percent.
This task addresses a very important issue about precision in reporting and understanding statements in a realistic scientific context.
For example, in the The decay constant has dimensions of reciprocal seconds.
In the special case in which parent and daughter atoms are present in equal quantities, the age of the specimen is the half-life of the parent isotope: The first assumption, that the amount of the daughter isotope in the original rock is known, is the weakest assumption.
Other resources report this half-life as the absolute amounts of 30$ years, or sometimes simply 00$ years.Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.To date an object, scientists measure the quantity of parent and daughter isotope in a sample, and use the atomic decay rate to determine its possible age.The proportion of argon to radioactive potassium in the sample today is observable, and the decay constant of potassium is readily calculable by measuring the amount of argon produced from the decay of K after a specified time.But the age of the rock and the proportion of argon to radio-potassium in the sample originally are not observable.This is not an example of malfeasance, but rather the result of assuming that the theory of evolution has been proved reliable, and therefore these seeming anomalies are due to contamination or other causes of analytical error.These out of place fossils or rocks are not considered a reason to question the theory.For example, K-Ar dating assumes that there was no argon in the original rock.But if there was argon in the rock when it originally formed, then the age calculated will be millions of years too high. The greater the amount of daughter isotope, the greater the apparent age.Other methods such as Potassium-argon dating and Isochron dating are based on faulty assumptions and so unreliable as to be useless.Many atoms (or elements) exist as numerous varieties called isotopes, some of which are radioactive, meaning they decay over time by losing particles.
