Here are the three major assumptions for your consideration: Are these foundational assumptions reasonable?
The numbers 238 and 206 represent these isotopes' atomic mass.
The Uranium-238 radioisotope goes through 13 transitional stages before stabilizing into Lead-206 (U238 Pb206).
In this instance, Uranium-238 is called the "parent" and Lead-206 is called the "daughter".
By measuring how long it takes for an unstable element to decay into a stable element and by measuring how much daughter element has been produced by the parent element within a specimen of rock, scientists believe they are able to determine the age of the rock.
This belief is based upon three significant assumptions.
Radiometric Dating - The Assumptions Many of the ages derived by radiometric dating techniques are highly publicized.
Nevertheless, the fundamental assumptions employed are not.
Radiometric Dating - A Brief Explanation Radiometric dating is the primary dating scheme employed by scientists to determine the age of the earth.
Radiometric dating techniques take advantage of the natural decay of radioisotopes.
