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.Explosive volcanoes brought them to the earth’s surface very rapidly in “pipes.” As the hardest known natural substance, these diamonds are extremely resistant to chemical corrosion and external contamination.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.NSF Postdoctoral Research Fellow at Stony Brook University.

It is literally able to count carbon-14 atoms one at a time.3 This machine can theoretically detect one radioactive carbon-14 atom in 100 quadrillion regular carbon-12 atoms! AMS instruments need to be checked occasionally, to make sure they aren’t also “reading” any laboratory contamination, called background.

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.

These findings are reported in the secular scientific literature (but they are usually rejected as measurement errors).

This chart shows the percentage of radiocarbon that remains in 40 samples from various layers throughout the geologic column.

(This percentage, technically known as percent modern carbon [p MC], shows the ratio of radiocarbon in the rocks and fossils compared to the amount we find in living things).
