Potassium argon dating
Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.
As a result, there is a changing ratio of carbon-14 to the more atomically stable carbon-12 involves actually counting individual carbon-14 atoms.
Analysis becomes difficult , if we do not have any confirmed data to establish the age of the artifact.
In the quest of establishing the date of an artifact, advance in technology helps us every time. Potassium argon dating is one of many methods used to determine the age of artifacts.
In addition, any argon that existed prior to the last time the rock was molten will have been driven off by the intense heat.
As a result, all of the argon-40 in a volcanic rock sample is assumed to date from that time.
One half-life is the amount of time required for of the original atoms in a sample to decay.
Over the second half-life, of the atoms remaining decay, which leaves of the original quantity, and so on.
A French physicist BARNARD BRUNSHES, initiated this theory. He is a junior at Wichita State University and pursuing his undergraduate degree in Mechanical Engineering.discovered the β-activity of Potassium atom in 1905.After this discovery later they found the γ-activity of Potassium atom in 1928 by KOHLHÖRSTER.In case of C-14, it can be used in restricted conditions, which the object would have to contain some amount of carbon to be visible.Carbon can only come from living organisms or the things which lived in past.This allows the dating of much older and smaller samples but at a far higher cost.Although, organic materials as old as 100,000 years potentially can be dated with AMS, dates older than 60,000 years are still rare.In the vast field of archaeology, determining the age of any object is very crucial and difficult.Crucial because, if we make a mistake in determining the age of an artifact, then we will have an inaccuracy in our interpretation, about that particular artifact.Since our dating technique is named Potassium-Argon dating Why do we need Potassium-Argon or K-Ar dating while another dating techniques such as C-14 work just fine.Other dating techniques work fine, but have their limitations.
