The fact that the C doesn’t matter in a living thing—because it is constantly exchanging carbon with its surroundings, the ‘mixture’ will be the same as in the atmosphere and in all living things.
As soon as it dies, however, the C ration gets smaller.
The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
When granite rock hardens, it freezes radioactive elements in place.
Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
The most common radioactive element in granite is Uranium-238.
This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.
A recent overview can be found in Manfred Bietak and Felix Höflmayer, Introduction: High and Low Chronology, pp. Manfred Bietak and Ernst Czerny, Vienna: Österreichischen Akademie der Wissenschaften, 2007.
Because of the inconsistencies and uncertainties of C14 dating, most archaeologists prefer historical dates over C14 dates.
Libby received the Nobel Prize in Chemistry for his work in 1960.
