Such an extraordinary claim requires extraordinary evidence to back it up, and since this is a complicated subject, it requires some preliminary explanations so that the details of this claim and the evidence for it can be readily understood.Every chemical element is made up of atoms unique to it.

Suppose A is very old (or appears very old) and B is very young. Their perceived radiometric age would then be between that of A and B.
North Carolina State University has recently conducted research revealing an “oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples,” which means that “scientists have likely overestimated the ages of many samples.” This research was done in the university’s Nuclear Engineering Department by Associate Professor Robert Hayes and a report published in the journal Nuclear Technology.1 To claim a key flaw has been found in the radioisotope dating methodology, which underpins the millions-of-years edifice of all modern secular geology, is quite extraordinary.
However, it is easy to imagine scenarios that could cause isochrons to yield false daates, and geologists recognize that isochrons can yield bad dates.
The idea of isochrons is this: Suppose X is a parent element that decays in to Y and Z is another isotope of Y not produced by radioactive decay. Since Y and Z are isotopes, we would assume they have similar chemical properties.
However, the number of neutrons in the nucleus of each atom is not always the same.

In this system, the radioactive parent rubidium-87 ( ..the critical assumptions stated above.
In uranium–lead dating, minerals virtually free of initial lead can be isolated and corrections made for the trivial amounts present.
These correlations must reflect either an isochron-type relationship or the trapping of an unknown component in the diamonds.
