The three key underlying assumptions are 1) the rate of decay of parent into daughter has remained constant throughout the unobservable past; 2) the specimen which we are examining hasn’t been contaminated in any way (that is, no parent or daughter has been added or taken away at any point during the unobservable past), and 3) we can determine how much parent and daughter were present at the beginning of the decay process – not all of the Pb206 present today necessarily came from decaying U238; Pb206 may have been part of the original constitution of the specimen.
In this particular case, it takes 4,460,000,000 years for half of a sample of U238 to decay into Pb206.
How does the geologic timescale fit with the view of a young earth?
According to Dr Ingrid Soto, chief of nutrition at children hospital J. de los Ríos, so far this year 65 kids have been admitted, whereas in all of 2015 the total was 35.
This rare, unstable isotope is produced from ordinary nitrogen 14.
In earth's upper atmosphere, on the edge of what is commonly called outer space, light atomic nuclei from unknown sources outside of our solar system traveling at speeds approaching the speed of light called rain down continuously.
Is there any evidence for the Bible's view of a young earth?
What is Progressive Creationism and is it biblical?
There still remains a lot of research to do, but, as it currently stands, the accuracy of radiometric dating remains ambiguously suspect at best.

This is at first glance surprising for long-agers, because of the ease with which one would expect helium (with its tiny, light, unreactive atoms) to escape from the spaces within the crystal structure.
There should surely be hardly any left, because with such a slow buildup, it should be seeping out continually and not accumulating.
These isotopes are stable, which is why they are with us today, but unstable isotopes are also present in minute amounts.
