Answers to radiometric dating assignment
Is there any evidence for the Bible's view of a young earth?
What is Progressive Creationism and is it biblical?
By measuring the amount of uranium and ‘radiogenic lead’ in these crystals, one can calculate that, if the decay rate has been constant, about 1.5 billion years must have passed.
(This is consistent with the geologic ‘age’ assigned to the granites in which these zircons are found.) There is a significant amount of helium from that ‘1.5 billion years of decay’ still inside the zircons.
Most people, even the experts in the field, forget the assumptions on which radiometric dating is based.
Creationists often criticize the methods as giving totally false results.
All of these dating methods begin with some radioactive isotope such as U-238, U-235, Th-232, K-40, or Rb-87. These elements are naturally radioactive, that is, they spontaneously emit an alpha or a beta particle and, as a result, are transformed into some different element, called the “daughter” isotopes.
It’s never used for non-organic samples, and almost never even attempted if the sample is thought to be much older than about 50,000 years.
It furnishes some good evidences that creationists often use.
