# Proof radiometric dating accuracy systems, radiometric dating

This is well-established for most isotopic systems. Not have any of the daughter components present in the initial system. It is done by comparing the ratios of parent and daughter isotopes relative to a stable isotope for samples with different relative amounts of the parent isotope. The age is calculated from the slope of the isochron line and the original composition from the intercept of the isochron with the y-axis.

For all other nuclides, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time. Radioactive isotopes and the age of the earth Until recently, only a large scientific laboratories could afford mass spectrometers, which are the principal tool used to measure dates of rock samples. The latest high-tech equipment permits reliable results to be obtained even with microscopic samples. The mathematics for determining the ages from the observations is relatively simple. Just how reliable are these dates?

Additionally, lavas of historically known ages have been correctly dated even using methods with long half-lives. There will be further postings about other dating methods. As the mineral cools, the crystal structure begins to form and diffusion of isotopes is less easy. These temperatures are experimentally determined in the lab by artificially resetting sample minerals using a high-temperature furnace. However, local eruptions of volcanoes or other events that give off large amounts of carbon dioxide can reduce local concentrations of carbon and give inaccurate dates.

This possibility is evident in the case of modern volcanic eruptions. This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture. Essentially all of these strongly favor an old Earth.

Or blatant acceptance of obvious fallacies? Is it possible to know the original components of a system formed billions of years ago? Clementson performed detailed studies on modern volcanic rock, and endeavored to obtain their radiometric ages. The basic equation of radiometric dating requires that neither the parent nuclide nor the daughter product can enter or leave the material after its formation. The age of prehistoric artifacts, the age of the earth, and that of the universe would be thrown into doubt.

Since the establishment of the system, the decay or process rate has remained stable and unchanged. At a certain temperature, the crystal structure has formed sufficiently to prevent diffusion of isotopes.

The overall reliability of radiometric dating was addressed in some detail in a recent book by Brent Dalrymple, a premier expert in the field. Finally, correlation between different isotopic dating methods may be required to confirm the age of a sample. Therefore, based on the certain amounts of the components in a sample, you can tell how old the sample is. Of the dating methods that we will examine, the Uranium methods will be the first.

Why would a radioactive element decay? This normally involves isotope-ratio mass spectrometry. These methods provide valid age data in most instances, although there is a small percentage of instances in which even these generally reliable methods yield incorrect results.

Reliability of **radiometric** dating So, are **radiometric** methods foolproof? This shows we should not trust radiometric dating. There are well over forty different radiometric dating methods, will i am dating geri halliwell and scores of other methods such as tree rings and ice cores.

The technique has potential applications for detailing the thermal history of a deposit. Is there such a thing in nature as a closed system? The idea that a system in nature could remain closed that is, not influenced by any outside sources for millions or billions of years is absurd to the highest degree. To obtain a proper date, you would need to compensate for the fluctuating process rate. Most of the decay rates used for dating rocks are known to within two percent.

Why should Uranium methods be assumed correct on rocks of an unknown age, when it is known that the methods are incorrect on rocks of a known age? If one of the factors changes, the rate is altered. The scheme has a range of several hundred thousand years.

That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. We are told that there are methods by which we can determine accurately the age of this incredible earth.

Over a thousand research papers are published a year on radiometric dating, essentially all in agreement. Such small uncertainties are no reason to dismiss radiometric dating.

Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades. As we progress further in this evaluation, we will examine the actual processes by which these methods work, and carefully determine their validity and accuracy. The use of different dating methods on the same rock is an excellent way to check the accuracy of age results. Accuracy levels of within twenty million years in ages of two-and-a-half billion years are achievable. All these are facts about the dating systems.

And it has been close to a hundred years since the uranium decay rate was first determined. From this one can determine how much of the daughter isotope would be present if there had been no parent isotope. The mass spectrometer was invented in the s and began to be used in radiometric dating in the s. There are only a few different dating methods.

If it were changed, then any calculation of the earth's age or the sample's age would be incorrect. The public is usually welcome to and should! What I can do is measure the age of the earth. The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.

This is direct evidence that the nuclear constants were the same billions of years ago. Thus an igneous or metamorphic rock or melt, which is slowly cooling, does not begin to exhibit measurable radioactive decay until it cools below the closure temperature. For this a batch of the pure parent material is carefully weighed and then put in front of a Geiger counter or gamma-ray detector. What we have is multiple independent lines of cohesive evidence that the world is billions of years old.

These instruments count the number of decays over a long time. According to evolutionists, there were no humans around during that time, so the notion that we can know the original components is once again absurd. Need to be a closed system. Therefore, it in itself is a faulty dating method. Here again much chemical activity is known to take place and widely diverging ages can be measured on samples from the same spot.

## Radiometric dating

Have the same process rate. Anyone can move the hands on a clock and get the wrong time.

In order to correctly understand the issue, you must come to an understanding of the process or mechanics behind the idea of radiometric dating. Both long-range and short-range dating methods have been successfully verified by dating lavas of historically known ages over a range of several thousand years.

This is also true of anomalies noted in carbon dates. When an organism dies, it ceases to take in new carbon, and the existing isotope decays with a characteristic half-life years. The fission tracks produced by this process are recorded in the plastic film.
