Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles.
“But a lot of people just refer to this as ‘Marvin’s Machine.'”The process is important because, unlike other methods of radiocarbon dating that destroy the sample being tested, LEPRS preserves it.
It also works on tiny samples – even a flake of ink or paint – and is considered a more accurate means of dating.“With standard radiocarbon dating, there’s a risk of contamination of carbonates.
They have to use acids and, within that process, you lose a large part of your sample and you destroy it,” Blinman explained.
“But we now have the ability to date incredibly small amounts of carbon – 40-100 millionths of a gram – and that is the real revolutionary aspect of this.
ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.
