All these results have been reported in the conventional scientific literature. At current decay rates, the number of radiocarbon atoms is halved every 5,730 years.
Because of this exponential decay, carbon-14 atoms can’t survive millions of years.
If the radioactive element carbon-14 breaks down quickly—within a few thousand years—why do we still find it in fossils and diamonds?
It’s a dilemma for evolutionists, who believe the rocks are millions of years old. Radiocarbon (carbon-14) is a very unstable element that quickly changes into nitrogen.
Pieces of fossilized wood in Jurassic rocks, supposedly millions of years old, yielded radiocarbon “ages” of only 20,700–28,820 years.
For some years creation scientists have been doing their own investigation of radiocarbon in fossils.
Also, the tight bonding in their crystals would have prevented any carbon-14 in the atmosphere from replacing any regular carbon atoms in the diamond.Yet diamonds have been tested and shown to contain radiocarbon equivalent to an “age” of 55,000 years.14 15 These results have been confirmed by other investigators.16 So even though these diamonds are conventionally regarded by evolutionary geologists as up to billions of years old, this radiocarbon has to be intrinsic to them.This carbon-14 would have been implanted in them when they were formed deep inside the earth, and it could not have come from the earth’s atmosphere.So rock samples that should read zero are occasionally placed into the instruments to test their accuracy.
What better samples to use than fossils, coals, and limestones, which are supposed to be millions of years old and should have no radiocarbon?
Most laboratories measure radiocarbon with a very sophisticated instrument called an accelerator mass spectrometer, or AMS.
