The most widely used evidence for the theory of evolution through natural selection is the fossil record.
Various confounding factors that can adversely affect the accuracy of carbon-14 dating methods are evident in many of the other radioisotope dating methods.
Radiometric dating methods use this basic principle to extrapolate the age of artifacts being tested.
How is half life used in radiometric dating
Half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.
Question should be whether or not carbon-14 can be used to date any artifacts at all?
Although the half-life of some of them are more consistent with the evolutionary worldview of millions to billions of years, the assumptions used in radiometric dating put the results of all radiometric dating methods in doubt.
Half life used in radiometric dating
Below is a chart of commonly used radiometric isotopes, their half-lives, and the daughter isotopes they decay into.
While there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, e.
There are so many complicated phenomena to consider like this that it calls the whole radiometric dating scheme into question.
This human nuclear activity will make precise dating of fossils from our lifetime very difficult due to contamination of the normal radioisotope composition of the earth with addition artificially produced radioactive atoms.
Any radiometric dates that show a supposedly old rock to be young are rejected for no other reason:few people realize that the index fossil dating system, despite its poor assumptions and many problems, is actually the primary dating tool for geologic time.
This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).
The problems inherent in radiometric dating often cause them to be so unreliable that they contradict one another rather than validating each other.
Dating cannot be used on most fossils, not only because they are almost always allegedly too old, but also because they rarely contain the original carbon of the organism that has been fossilized.
This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.
However, your read out from your radioactivity measuring instrument says you have only 25% carbon-14 and 75% nitrogen-14, so your fossil must have been through more than one half-life.
A scenario does not answer all of the questions or solve all of the problems that radiometric dating poses for those who believe the genesis account of creation and the flood.
-life is defined as the time it takes for one half of a radioactive element to decay into a daughter isotope.
This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.
Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.
All dating methods that support this theory are embraced, while any evidence to the contrary, e.
