What is radioactive dating?

Radioactive dating is a method for calculating the age of rocks and fossils through concentrations of certain radioactive elements in close proximity to such objects or as part of their chemical structure. There are different methods of radioactive dating used depending on whether it is analyzed, is organic or inorganic, and each process is based on the assumptions of the original state of the dated and received geological time. While the nature of the radioactive decay is based on established scientific principles for radioactive elements that are well proven, the prerequisites used to calculate the actual age of the object from these principles are subject to debate and controversy.

Radioactive dating of carbon is the most common method used for today's fossil of human origin or artifacts from ancient human civilizations. Isotope of carbon 14 ( 14

C) nunIt is because it has an effective short half -life of 5,725 years, when it decomposes into nitrogen 14 ( 14 through breathing processes. After the plant or animal has died and is sealed from another exposure to the air, the amount of carbon 14 slowly reduces the remains even in the surrounding soil. This variant can be compared to atmospheric concentrations to determine the rough age when the creation died, or when it was buried in the soil near organic residues.

Methods of radioactive dating for older periods or fossils, which are assumed to be millions of years old, include the use of elements with a much slower decay than carbon 14. Uranium 238 ( 238 ) is usually used, as slowly decomposing lead form ( 206

PB)over 4,500,000,000 years. Another isotope with a long disintegration that is still used by geological formations is the potassium 40 ( 40 k), which extends over Argon 40 ( 40 AR) in 1,250,000,000 years. While radioactive elements, such as carbon or uranium isotopes, remain unaffected by other processes that take place around them, such as changes in heat, pressure and chemical reactions. As a result, they are predictable in terms of their degree of change and their disintegration rate is the basic prerequisite on which the science of radioactive dating is built.

The primary argument of the accuracy of radioactive dating is concentrated around the science of geological age, it has been assumed for the country, since 2011. Because it is impossible for people to recognize the exact state of the rock or the fossil deposit of NT. Elements that seem to be by -products of the decay may be stored in the sample over time by other methods or always in higher thanExpected concentrations together with decaying elements and discarding calculations about the actual age of the building. Tests of the age of recently formed rocks of volcanic eruptions, several independent laboratories, also brought wild different ages for several million years, when the rocks were created through processes that occurred less than 100 years ago, and condemned some doubts about the methodology used in conventional procedures.
