Obviously there will usually be a loss of stable carbon too but the proportion of radiocarbon to stable carbon will reduce according to the exponential decay law: R = A exp(-T/8033) where R is C ratio of the living organism and T is the amount of time that has passed since the death of the organism.
By measuring the ratio, R, in a sample we can then calculate the age of the sample: T = -8033 ln(R/A) Both of these complications are dealt with by calibration of the radiocarbon dates against material of known age.

An “isotope” is any of several different forms of an element, each having different numbers of neutrons.
The illustration below shows the three isotopes of carbon.
The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism.
In general it is always better to date a properly identified single entity (such as a cereal grain or an identified bone) rather than a mixture of unidentified organic remains.Further complications arise when the carbon in a sample has not taken a straightforward route from the atmosphere to the organism and thence to the measured sample.Carbon-14 can be used to date organic material that was once alive such as wood, animal hair, skin, or soft tissue, unmineralized bones, and even mineralized bones after the minerals have been removed. Many scientists, students, and others are now acknowledging that Dinosaurs probably didnt go extinct 65 million years ago, but in the recent past: which explains why they are described in the Old Testament, 11.

Because the carbon present in a plant comes from the atmosphere in this way, the radio of radiocarbon to stable carbon in the plant is virtually the same as that in the atmosphere.
