On the inaccuracies found using the Carbon-14 dating method, and the various other radioactive dating methods.
Amount of cosmic rays penetrating the earth's atmosphere affects the amount of 14c produced and therefore dating the system.
To answer this question, it is necessary to scrutinize further the experimental results from the various dating techniques, the interpretations made on the basis of the results and the assumptions underlying those interpretations.
These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.
Other types of radiometric dating
One example is k-ar dating of five historical andesite lava flows from mount nguaruhoe in new zealand.
And when early devonian rocks are dated radiometrically, we get dates of roughly 400 million years.
, an expert in the environmental fate of radioactive elements, identified 17 flaws in the isotope dating reported in just three widely respected seminal papers that supposedly established the age of the earth at 4.
If a contradiction occurs, then the cause of the error needs to be established or the radiometric results are unacceptable.
Other forms of radiometric dating
In reality, all dating methods, including those that point to a young earth, rely on unprovable assumptions.
With uranium-lead dating, for example, the process assumes the original proportion of uranium in the sample.
Radiometric dating methods are widely quoted by scientists, they are inappropriate for aging the entire universe due to likely variations in decay rates.
Then cross-matching of ring patterns is used to calibrate the carbon clocka somewhat circular process which does not give an independent calibration of the carbon dating system.
Types of radiometric dating
Dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant (see below for the flaws in that assumption) and measuring the amount of radioactive decay that has occurred.
, tests of radiometric dating methods have often shown that they do not agree with known ages of rocks that have been seen to form from volcanic eruptions in recent and historic times, and there are also examples of radiometric dating methods not agreeing with each other.
Example, with uranium-lead dating with the crystallization of magma, this remains a closed system until the uranium decays.
For example, the sample record sheet for the university of waikato radiocarbon dating laboratory asks for the estimated age, the basis for the estimate, and the maximum and minimum acceptable ages.
Dating, with its much lower maximum theoretical range, is often used for dating items only hundreds and thousands of years old, so can be calibrated in its lower ranges by comparing results with artifacts who's ages are known from historical records.
The do the radiometric dates of millions of years mean, if they are not true ages?
Is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years.
Radiometric dating fails to satisfy standards of testability and falsifiability, claims based on radiometric dating may fail to qualify under the daubert standard for court-admissible scientific evidence.
The case of carbon dating, it is not the initial quantity that is important, but the initial ratio of c14 to c12, but the same principle otherwise applies.
 there have been many attempts, because the orphan halos speak of conditions in the past, either at creation or after, perhaps even during the flood, which do not fit with the uniformitarian view of the past, which is the basis of the radiometric dating systems.
Olsson, c14 dating and egyptian chronology, in radiocarbon variations and absolute chronology, proceedings of the twelfth nobel symposium, ingrid u.
 such a re-calibration makes sense of anomalous data from carbon datingfor example, very discordant dates for different parts of a frozen musk ox carcass from alaska and an inordinately slow rate of accumulation of ground sloth dung pellets in the older layers of a cave where the layers were carbon dated.
Understand the limitations of dating methods better than evolutionists who claim that they can use processes observed in the present to prove that the earth is billions of years old.
This would make things look much older than they really are when current rates of decay are applied to dating.
This would make things which died at that time appear older in terms of carbon dating.
For these reasons, if a rock strata contains zircon, running a uranium-lead test on a zircon sample will produce a radiometric dating result that is less dependent on the initial quantity problem.
