Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus.

A decrease in the earth's magnetic field, increases C And that increased CO2 carbon dioxide levels, decrease C So we can assume that the ratio decreased during the industrial revolution, due to factory generation of CO2, and during other such natural events Therefore, using an assumed constant ratio for dating inevitably results in inaccurate radiocarbon readings.

And there is no way to prove that the decay rate was not different at some point in the past.

### Apologise, but, accuracy of radiometric dating methods opinion

These two problems alone, in reality, clearly calls into question the validity of virtually any dates assigned to fossils. Carbon actually decays so quickly-with a half-life of only 5, years-that none is expected to remain in fossils after only a few hundred thousand years.

Specifically, a process called radiometric dating allows scientists to determine the ages of objects, including the ages of rocks, ranging from thousands of years old to billions of years old to a marvelous degree of accuracy. Nov 27, Now that we know how radiometric dating actually works, let's see the evidence of its inaccuracy and unreliability with two major radiometric dating methods Carbon Dating Carbon actually decays so quickly-with a half-life of only 5, years-that none is expected to remain in fossils after only a few hundred thousand years. Apr 27, These same people say that science is important. Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of .

Mammoth Dating Inconsistencies. A fossilized baby mammoth nicknamed Dima, was dated by Dr.

Brown The radiocarbon dating indicated that one section of Dima's body was 40, years old, while another part was 26, years old.

## Something is. accuracy of radiometric dating methods excited

After C dating a dinosaur fossil, the Oak Ridge National Laboratory, located near Knoxville, Tennessee, indicated that the dating results showed the fossil to be just a few thousand years old, not millions.

Not wanting to abandon their preconceived notion that dinosaurs have not existed for the past 65 million years, however, their evolutionary researchers dismissed the results as invalid.

Thermal ionization mass spectrometer used in radiometric dating. Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon, or a long-life radioactive element plus its decay product, e.g., potassium/argon

This is not an isolated case. Scientists often reject dating results that do not fit their theories. Blind Dating.

### How accurate is radiocarbon dating?

Inconsistent Dates By Far. In the Geological Survey Professional Paperthey carbon dated sample SI and said it was 17, years plus or minus They then tested a different sample, sample SI, and said it's 24, years old.

The very same sample, tested again. So is it 17, or 24,? This same mistake happened again Sample was claimed to be less than 20, years old, and Sample L was greater than 28, They then find out it was the same sample as How can a sample be less than 20 and greater than 28 at the same time?

Jan 23, Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample. It is founded on ufatgirlnmotion.comovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant. Radiometric dating is a much misunderstood phenomenon. Evolutionists often misunderstand the method, assuming it gives a definite age for tested samples. Creationists also often misunderstand it, claiming that the process is inaccurate. Radiometric Dating Is Not Inaccurate. Many people think that radiometric dating has proved the Earth is millions of years old. That's understandable, given the image that surrounds the method. Even the way dates are reported (e.g. ± million years) gives the impression that the method is precise and reliable (box below).

Known Dates Inaccurate. Living penguins have been dated as 8, years old.

# Accuracy of radiometric dating methods

Material from layers where dinosaur bones were found have been carbon dated at 34, years old. A freshly killed seal was 1, years old when they carbon dated it.

Living snails have been carbon dated 27, years old. They tested a living mollusk, a clam, and it was 2, years old. It was still alive.
