What is uranium dating used for
When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.
This collision is less destructive than the initial collision that produced them.
PROBLEMS WITH RADIOCARBON DATING During the last 30 years, a new method of determining C14/C12 ratios has been developed.
It uses accelerator mass spectrometry to determine the amounts of C14 and C12 in a small sample which is vaporised in the test.
As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom. The age of a rock can be calculated if its ratio of uranium to lead is known. This is unstable and eventually decays to lead, which is stable.Radiocarbon dating has somehow avoided collapse onto its own battered foundation, and now lurches onward with feigned consistency.The implications of pervasive contamination and ancient variations in carbon-14 levels are steadfastly ignored by those who base their argument upon the dates.
