These statements spring from an argument developed by cook (28) that involves the use of incorrect assumptions and nonexistent data.
How radiometric dating works in general : Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the
The geochronologist takes this factor into account when assigning experimental errors to the calculated ages.
