How is radiactive dating performed

We are told that these methods are accurate to a few percent, and that there are many different methods.

After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.

I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.

Even the creationist accounts that I have read do not adequately treat these issues.

At the start, let me clarify that my main concern is not the age of the earth, the moon, or the solar system, but rather the age of life, that is, how long has life existed on earth.

This method of dating was discovered in the 1940s by a team of researchers lead by Willard F. The Nobel Prize in Chemistry was awarded to Libby in 1960 for his leadership in developing radioactive dating.

How radiometric dating works in general Why methods in general are inaccurate Why K-Ar dating is inaccurate The branching ratio problem How Errors Can Account for the Observed Dates Why older dates would be found lower in the geologic column especially for K-Ar dating Do different methods agree with each other on the geologic column?

The radiation causes charge to remain within the grains in structurally unstable "electron traps"..

While uranium is watersoluble, thorium and protactinium are not, and so they are selectively precipitated into oceanfloor sediments, from which their ratios are measured.

) Shortly after the discovery of the neutron in , Enrico Fermi realized that certain rare betadecay reactions immediately yield neutrons as a decay particle (neutron emission).

Age "uncertainty" When a "simple" dating method is performed, the result is a single number. Also, an increase in the solar wind or the Earths magnetic field above the current value would depress the amount of carbon14 created in the atmosphere. Crosschecks between different isotopes with different chemical properties.

Radiometrically measured age of meteorites, and is also about 500,000,000..
